A Photograph of the Loch Ness Monster?

Trawling around the Internet as I do for Nessie information, I came across this photograph on a website compilation of holiday snaps. The owner of the picture had been to Scotland and elsewhere in Europe from the USA and had decided to put up a montage of her experiences. However, one of the pictures shows something a bit more than normal.




Here is a zoom in on the object of interest. It would appear the the picture was taken on the 15th July 2006 but the camera time is set at 0421. The location is given as a point off the Clansman Harbour at the north end of the loch but closer to the opposite shore, so the photographer was probably on a cruise boat (see map below).





Now I have tried several times to contact the owner of this photograph (who I believe is called Nancy) but without success and this basically leaves me in a bit of no-man's land. The reason I say that is because if I did establish contact the day after this article posted, several replies may be forthcoming. 

For example, the owner may say "It's a Photoshop job, I was just fooling around.". In that case, there is not much more to say and we move on.

Or she may say that is a genuine picture and we can take it from there.

Or she may come up with some other reply such as "The cruise boat had a Nessie sticker on the window for tourist Nessie snaps."

Of course, it may be the photographer is unable or unwilling to make contact.

But despite these unknowns, perhaps this is an opportunity to explore an area of Loch Ness Monster images that provokes debate. I am referring to digital images of the creatures and the argument over whether they are digitally manipulated images.

Of course, manipulated images of the Loch Ness Monster go hand in hand with the mystery itself. The 1977 Shiels picture is perhaps the best example, but the MacNab picture from 1955 has also been put under the scrutiny of sceptical enquirers.  However, such alleged images form a small part of the overall set of images. Others have been accused of being staged props or misidentification, the rest are genuine images of the creature.

PHOTOSHOPPING

Now one question levelled by sceptics today is why the clarity of the classic black and white pictures is not repeated today with superior cameras. However, when a photograph such as this turns up, it is automatically dismissed as a fake. Damned if you do, damned if you don't. The "too good to be true" syndrome kicks in almost by instinct.

Now it may not have escaped your attention that the lake cryptid world has no lack of digitally faked images. A search for images of "loch ness monster" on google will throw up a good number of such "photoshopped" images (to quote the vernacular for such images). How can you distinguish the real from the fake? For me, this photograph is the catalyst to explore this more modern aspect of cryptid forensics more closely.

At the "lowest" level of analysis, the aforementioned snap judgements are oft to the fore. A picture appears on a cryptid website and not long after we get the photoshopping comments. People will look at such images and get a "feel" for whether it looks right or not. Of course, this involves a mixture of objective and subjective assessments, but we need something that eliminates the subjective.

At this point, I would have to point out that there are two types of photoshopped images, those that are intended to deceive and those that are intended as an obvious joke. The latter are not that difficult to spot. Those that intend to deceive put a bit more effort into their creation.

IMAGE ANALYSIS

One website I consulted gave five rules for detecting a Photoshop event:

1. "Software" metadata in image file is "Photoshop"
2. Image is compressed to JPEG file by Photoshop (which has some unique pattern)
3. Image is compressed to JPEG file twice (which has some other unique pattern)
4. Part of image has been cloned from another part of it
5. Image color or brightness is deemed abnormal which should be manipulated

I can't say I will exhaustively apply all these principles today - I am no expert on digital manipulation - but the need to "ramp up" on this aspect of Loch Ness Monster investigation has become more apparent to me.

On the first point of the metadata, this is part of the Exif (Exchangeable image file format) data that makes up JPEG, TIF and WAV image files. This data contains information on the circumstances of the image such as camera make and model, date and time, exposure time and focal length. Since the data does not actually describe the image, it is called metadata. You can see this for yourself on a Windows system by right clicking on a picture file and selecting "Properties".

However, on trying some images, finding the clue of subterfuge via the metadata was not as clean cut as one may think. One website that seems to be popular in looking for anomalies is imageedited.com.  This will run some basic tests on an uploaded image file and hazard a guess as to whether the image has been changed. 

When I ran this photograph through it, the decision as to whether image editing had occurred was "Probably" though it did not list any image editing software as a culprit. Is this a decisive conclusion? I do not think so. When I ran another of the owner's photographs from Loch Ness which was no more than an ordinary snap of the castle, it gave the same result!

It seemed apparent to me that both images had undergone some changes in preparation for web site hosting. One possible explanation being the downsizing of the image to a smaller size. I also wondered if an editing software program could be masked by running it through a subsequent, less suspicious program?

MORE DETAILED ANALYSIS

Seeking to take this further, I came upon the website fotoforensics.com. On top of the metadata analysis I just mentioned, two further tools are employed to ascertain the originality of a photographic image. The first is called Error Level Analysis ("ELA" hereafter). This works on the principle that a JPEG image should uniformly and roughly have the same level of data compression (JPEG is a process which compresses the original image to a smaller file size but usually with the loss of information). Any differences in compression rate in an image is suggestive of digital modification.

The website allows you to upload a file for ELA conversion which outputs an image. The guidelines given for that new image are summarised as follows:

Edges. Similar edges should have similar brightness in the ELA result. All high-contrast edges should look similar to each other, and all low-contrast edges should look similar. With an original photo, low-contrast edges should be almost as bright as high-contrast edges. 

Textures. Similar textures should have similar coloring under ELA. Areas with more surface detail, such as a close-up of a basketball, will likely have a higher ELA result that a smooth surface.

Surfaces. Regardless of the actual color of the surface, all flat surfaces should have about the same coloring under ELA.

With that in mind, I looked around for some faked Nessie pictures to analyze. In each pair, the first picture is the original and the one below is the ELA image. The first one presents an immediate problem as this white Nessie has an ELA which is higher (i.e. more complex) than the sky of a similar hue. 


The next picture is taken from Claudio Diaz's Lake Monster Facebook page. Claudio has produced various Photoshop reproductions and these provide an interesting comparison (indeed, Claudio's opinion on this matter is solicited). Here we see that the brightness of the edges around the "monster" are not consistent with other low/high contrast edges indicating a problem.



Another image from the Lake Monsters Facebook page shows a more indistinct hump image nestling within the reflection of Urquhart Castle. This fuzziness is mirrored in the indistinct lack of edge in the ELA image. A harder image to judge, but perhaps others have an opinion.




Now I bring in the same process for the main photograph of our interest. The result is that, unlike the other pictures, the object here is barely visible in the ELA image. Is this significant and is it an indication of no digital manipulation? Perhaps, but there is no foolproof technique here and it would have helped to have the original and larger image.


JPEG QUALITY

The second analysis tool is JPEG Quality. Each time an image file is opened in a graphics editor and resaved, there is a potential loss of image quality (this depends on the quality level selected). The loss of quality can be estimated and compared to other images. 

Using our fotoforensics tool, the JPEG quality is estimated to be 85%. When another of the Loch Ness holiday snaps from the owner was put through this filter, its quality level was also estimated to be 85%. This suggests both images went through the same sequence of events. If the Nessie photo had gone through an extra level of processing to add the "monster", then it would be possible for it to have a lower JPEG quality.

CONCLUSIONS

So, some conclusions may be reached, but I suspect an expert digital manipulator could produce an image which only experts could judge at the pixel level. Since the owner of the photograph has not replied to my requests, the jury has to remain out on this one.

But certainly, judging it purely as an image (independent of its source), it is a good one. You can see the precise detail that the object possesses as one observes the glint of the sun reflecting off the head and to a lesser extent off the humps. There is also the reflection of the neck on the water. Moreover, the image has packed more detail into a smaller area than the other images we compared here.

On the opposite side of the coin, the second hump to the left of the main hump looks out of place. What could that mean? Also, the zoomed in pixellated area to the left of the neck reflection looks a bit strange, but how valid is an image judgement when individual pixels are resolved?

So, I am bit new to this and would welcome comments from others who may have more experience of image analysis. I would also like to know when sceptics regard a photo as no longer "too good to be true" and not "photoshopped".

  2. The picture definitely looks tampered with. The water round Nessie looks smudged and less sharp than the rest of the water and Nessie herself looks less sharp, it doesn't look like motion blur which wouldn't be uniform over the object. It actually looks like an inexperienced retouchers (or a kids) attempt at compositing. As previously demonstrated by Dick Raynor (on another picture), with water like this there would be no shadow from the head and neck as can be seen here.

    To be fair the ELA does very much suggest that its not been tampered with, but there are various ways round that. If this was a retouched print that had been photographed, or even a picture photographed off a computer screen, it would appear as an unaltered jpg image.

    It looks more like a tribute to Frank Searle's post card series.

    1. Les, I did comment on that area, so that is a negative. But what I would like here is a more objective tool which makes our fallible, subjective judgements less important. These can't be totally eliminated when the provenance of a picture is unknown, but the less the better.

    The zoomed in version does have a bit of 'frank searle' about it..but i must say its very interesting. My thoughts would be that its fake as surely we would have heard more about the photo if not ??The second hump does indeed look as though it may even belong to a seperate creature as there seems to be a very slight 'something' a bit further on from the hump to the rear , possibly small head or something just submerging/surfacing ?? mother & baby nessie !!! would be good to get in contact with the person in question .

    Is there ever a point where a obvious fake is seen for what it is? Is there also a point where trying to use all the analytical mumbo jumbo to push unreality into reality for one's agenda is seen for what it is - damaging to the credibility and actual search for the Loch Ness Monster, whether it exists or not? These are the head-scratching moments for me.

  9. Shame we know GB would at some point be endlessly arguing that this is proof of Nessie if Claudio hadn't posted. And it yet again shows how modern technology has pretty much eliminated any possibility of vague and indeterminate photos like Gray's and Stuart's being created and argued over ad infinitum.
    The photos we know we'd have (if Nessie existed) in the modern age of high definition photography simply never materialise, because the clarity makes it easy for us to recognise when something doesn't look right.
    So all we have left now is a handful of blurry old black and white snaps, dead witnesses and events so lost in the mists of time that pretty much anything can be argued and people will just take the side they like the sound of.

    2. I eagerly await your article. I suspect it will include various "explanations" such as the size of the loch compared to the number of people watching with cameras; the unwillingness of people to say they have a photo because they fear ridicule; the Loch Ness "hoodoo", and maybe something about Nessie being scared by digital technology. ;-) All of which amount to nothing more than flimsy excuses.

    10. Neither really, I just love a good healthy debate and I certainly don't recognise any anger.

    11. I have argued repeatedly that in an age of immediate video access (i.e. almost every modern phone comes equipped with a camera), we rarely see motion picture of purported Nessies; and at best, we end of with ambiguous cell phone photos when it takes only a moment to select VIDEO MODE -- but we all know that shooting video of a floating object would settle the matter fairly quickly. Roland has argued unconvincingly against this point, but never at length. I eagerly await his upcoming article/rebuttal.

    14. And the most interesting point is that pretty much everyone now has a camera phone to hand as ekm says, which means that for every 10 people who see a giant hump or neck, 9 of those would be able to photograph or video it within seconds. Yet... nothing.

      Delete
    15. Your logic is faulty for it assumes the same conditions for every person. That is not the real world.

      Over what timespan have there been 10 head-neck sightings of the creature?

      Delete
    16. Pretty much everyone has had a camera phone for about 5 years, and I thought LNM reported sightings average at 10 a year, so that's maybe 40 sightings with a camera in hand or pocket. When you say "it assumes the same conditions for everyone", well if it's clear enough for a person to view it and be sure they're not seeing a natural phenomenon, then it should be clear enough to get something on their camera phone worth looking at.
      ok a question for you GB. How many more years without any good clear video footage will it take for you to start doubting? I'm asking that politely - I want to know if you have a "no clear evidence" threshold, after which you'll begin to think there might be nothing unusual there? Thoughts?

    17. Most people have camera phones. You've argued that because you don't, then that proves that the argument is fallacious, but I don't buy it.

    20. I just think believers want things both ways. On the one hand they argue that too many people have had clear unambiguous sitings for there to be no Nessie, yet on the other hand argue that the lack of any unambiguous photos or videos is down to the rarity of sightings, lack of cameras to hand, lack of clarity etc. It really doesn't work both ways. We either have a beast with footage, or no beast.

      Delete
    21. Yes, but you need to contrast what the human eye sees compared to a crappy mobile phone camera. They do not record the same way.

      Good, proximate sightings are rare and believe me, any photo of something at 100-200m will STILL be panned and dismissed by sceptics. So you can't win with that lot either! They want the pound of flesh, so comments about wanting good photos is insincere in my opinion.

    22. Evidence trumps untrained eyewitness testimony every time.

    23. I'm someone who has transitioned from being on the fence to a complete nonbeliever. I would be absolutely ecstatic if Nessie really existed. Which adult who played with dinosaur models as a child is not intrigued by the possibility of Nessie? I love mysteries as much as anyone, that's why I'm here!
      A film on or in LN which strongly suggests an unknown animal would be utterly amazing, I'd love it! But I've still never seen one. There isn't one. I don't need a corpse, I just need one good photo sequence (yes, it would be a sequence of repeated shutter presses) or one good video. It's the minimum anyone can expect if you want them to believe a large unknown animal inhabits the loch. I'm not being unreasonable, I'm being a normal, intelligent adult who requires proof to back up all the claimed sightings.

      Delete
    24. Define "evidence" and define "untrained".

      You also seem to distinguish between "evidence" and "untrained eyewitness testimony". Untrained is a function of how clearly the object in question is visible. Can you define that function?

      Delete
    25. "I'm someone who has transitioned from being on the fence to a complete nonbeliever."

      Well, we do have sequences such as the James Gray and Roy Johnson photos taken last decade - but again these are disputed on circumstantial evidence (not the photos themselves).

      Delete
    26. I just looked up the James Gray and Roy Johnston photos. Hilarious, especially Johnston's! If that skinny snake thing is supposed to be attached to a vast humped body, then (assuming it's a neck and tiny head) it must be having to catch food all day to support itself. Also, if you think nessie isn't an air breather - which seems to be the current thinking to explain the rare surfacings - then I can only assume you propose a tiny headed animal with a long neck attached to a big bulky body featuring gills on the body for underwater breathing? Or maybe some other cut and paste mish mash of animal parts? Gills on that tiny head wouldn't transport enough oxygen to a large body.
      I love all of this Nessie stuff cos it shows how far people are prepared to bend logic to back up their beliefs.

      Delete
    27. "Untrained eyewitness testimony" is the taking the word (honest? liar? could go either way!) of someone who knows very little about how deceptive Loch Ness can be, and assumes a standing wave is a giant monster. In other words, a person who doesn't know what they're looking at, sees something strange, and assumes that because it's Loch Ness, then it must be a monster.

      I don't need to define "evidence."

      Delete
    28. Yup, well, you're obviously not following what I have been thinking about heads and necks.

      Delete
    29. ekm, you do need to define evidence. If it means a piece of a body, no point in talking about eyewitness evidence, just leave that to others.

      How "untrained" do some witnesses have to be if they seem something at a 100 yards (as attested to by witnesses in the past)? Are you just going to go down the knee jerk hoaxer path?

      Delete
    30. I've read your page on retractable necks, and it seems to be a theory based on a couple of very old reports; furthermore it doesn't seem clear whether it's even a theory you subscribe to. And even if the neck of this imaginary creature were to extend and retract, the points above remain valid. A tiny head and skinny neck mean a bulky body receives only tiny meals. Feeding would have to be very regular. It also means the animal would be an air breather or if not would have gills on the bulky body, not the pin head. The thought of a hump like the boat in Dinsdale's film having a snake attached like the thing in Johnston's photos has me really chuckling.
      As an aside (but sort of related), I have a copy of The Dragon and the Disc. I started reading it once but had to stop after a few pages because it was just random garbled nonsense, like some kind of hippy's hallucinogenic dream. Back in those days a lot of very strange stuff made it into print.

      Delete
    31. You only accept "new" reports?

      It's a theory in the making, but yes the gills would have to be further down. However,water breather do not necessarily need gills to get oxygen.

      Well, D&D is a book of its time.

      Delete
    32. A water breather with flippers so well designed that they can propel the Dinsdale hump 10mph (according to yourself), yet the animal can suddenly climb out of the water and support its weight on these flippers, presumably by converting them into legs and feet. And also switch its breathing mechanism to suit walking across roads, possibly holding a sheep in that tiny mouth. Seriously, break all the "evidence" down and so many bits contradict eachother.

      Delete
    33. I think you are indulging in straw men arguments such as flippers going at 10mph are useless on land. How do other amphibious water breathers manage to get on and off land? Nature is full of them - even eels travel across land!

      I am not sure the creature needs its flippers to be the primary form of locomotion on land, though they would play a part. I mean, how do seals move on land? You are trying to make the impossible out of the possible.

      As for sheep in tiny mouths, I don't doubt it could be done (wherever the mouth is). So, seriously, I don't think ou are htinking this through properly and are just blunderbussing excuses.

      Delete
    34. Have you seen a seal or sea lion heaving itself around at the water's edge? Think one could climb hills and catch sheep? And a bulkier animal with flippers would be even slower and less able to climb anything.

      Please let me know about any large amphibious animals which show it's possible to be 10ft+, spend 99% of your life underwater, then actually go on land to hunt. Another question - do you genuinely think that neck in the surgeon's photo (or indeed the preposterous one in the Johnston photos) could carry a sheep?

      Come on Rowland, it doesn't all stack up. You simply have to drop something from the eyewitness accounts. When I spoke to Steve Feltham a few years ago even he said "Tales of sheep being carried into the loch don't help the cause."

    38. It grates somewhat that every time I point out gaping holes and big contradictions in the eyewitness testimony you refer to straw man arguments. The entire pro-Nessie camp survives on eyewitness reports, so let's take a closer look.

    40. Very good GB, just don't use 10,000 words explaining how it's photographic evidence of a sheep-stealing monster ;-)

      Interestingly, land sighting reports have all but vanished in recent times, but were seemingly fairly regular in the 1930s. I wonder why. Perhaps it could be that the early sightings were mistakes, and based on the excitement the myth was generating at the time?

      That is because they are straw men arguments! The contradictions tell me nothing that threatens the monster theory. I freely admit that a proportion of sightings are lies or misidentification. Therefore, these "accounts" are going to contaminate the database with non-existent feature descriptions.

    43. When every photograph contradicts the rest, and eyewitness reports contradict one another, we end up with an improbable animal without any defining characteristics save a "hump."

      Despite his fevered defense of the non-evidence, very little of which is complimentary, Roland has yet to put his writings in context and offer his hypothesis. What IS The Loch Ness Monstet, assuming these many "proofs" are what he believes them to be...? It's no secret that he was once a supporter of Holiday's Goblin Universe theory, which, insane as it may be, is the only way to reconcile these many "proofs."

    44. Perhaps that is because the only thing believers have - eyewitness testimony - is inherently flimsy? Therefore whenever we point out the contradictions we cannot help but use so called straw man arguments.

      On the point of debating style, I note that you quite frequently refer to sceptics as the "show me the body" camp, as though we are in some way being unreasonable by requesting biological evidence to back up quite extraordinary claims of a lake monster. Well yes, I do require something rather better than a few grainy (and contradictory) snaps plus eyewitness reports (again contradictory) in order to believe in a monster in the loch. And frankly so should you.

    45. Really? So why are eyewitness accounts allowed in courts of law if they are "inherently flimsy"? The point which you miss is that eyewitness accounts are allowable and it is down to the lawyers in courts to put them to the test. Your label of "flimsy" is just your opinion. The equivalent of prosecution lawyers in this field who dismiss everything as wakes, birds, etc would be "laughed out of court".

      You contradict yourself, not all are grainy and I have given my opinion why accounts/pictures contradict each other. If you do not acknowledge these things, then you are the one not engaging in deabte but probably trolling.

    46. Firstly, I am not trolling. I have a genuine interest in this subject, having made trips to the loch, and acquired a fairly large collection of books on the subject, including a mint first edition of Mackal's book.
      Secondly, I know that eyewitness testimony is admissible as evidence in a court of law. However, that evidence would be discarded if 1) it contained vastly contradictory details, or 2) it described actions or objects not known to science.

      Following your legal theme, let's imagine an ID parade of monsters and LNM witnesses being asked to point to the beast they saw. Which would they choose - the one with multiple snakelike coils with gaps between coils and water, or the single deep humped one? The one with rough brown skin or the one with smooth black skin? The one with the large horse's head with shaggy mane, or the one with no discernible head at the end of the neck? Giant eyes or no eyes? The one with flippers or the one capable of walking across the road?
      You see, none of these reports together would stand up in court at all.

      And science, specifically biology, does not progress on eyewitness reports, it progresses on specimen analysis. That is the only conceivable approach.

      Once again, I am not a troll, I am a person who is very interested in the LNM phenomenon, and I will strip down every argument for and against the "monster" into its component parts. It's the only sensible approach Roland.

    47. The point continues to be missed.

      The argument is NOT that eyewitness testimony is worthless -- the argument is that these eyewitness offer no visual corroboration when camera phones Reside is nearly every pocket. Where are the 1080p videos? If I can manage to grab my phone in time to capture my son taking his first unannounced steps, where is the footage of the Loch Ness monster?

      I don't understand why this line of thought is so difficult to follow, unless it is being willfully misconstrued.

    48. Come on, Roland, out with it: what do you hypothesize Nessie is? Enough with the articles on eighty-year-old photographs, it's time to put your cards on the table and offer a theory that supports your defense of these contradictory pieces of evidence. Ignoring the question doesn't make it go away.

    55. "Your demands for the perfect line up are unreasonable."

      If you look at the above conversation, you will see that you stated eyewitness testimony is admissible evidence in a court of law. I agreed, but the point of my post was to illustrate that the vastly contradictory Nessie eyewitness testimony would not be valid in any court of law.
      You may have your explanations for the discrepancies, but you cannot deny that all the different descriptions are a hindrance to your case. If people had been reporting the same features without digression for 80 years I am certain you would be using that to back your case.

      I wonder which features you'll decide to discard. Certainly since the publishing of the faked surgeon's photo the wild descriptions got a bit reigned in towards a plesiosaur shape. Even 40 years later the artist who painted over Rhines' blurred image seemed to have a plesiosaur in mind when he created that flipper and fobbed it off as "computer enhancement".

      Delete
    56. If no one had seen lions before, would you discard any testimony because one witness saw a small one (cub), a large one (female) and one with a mane?

      Again, you are indulging in straw men arguments and I seriously wonder if you have had a good look at the sightings database? The greatest distribution of descriptions mainly concern what is dubbed the head and neck. The great majority of sightings are just humps and have less variability. But you knew that, I presume?

      Delete
    57. Of course I know the descriptions over the years. A hump is just a hump and so the main variances will be size and number. The neck and head is more complex, and unsurprisingly there have been much wider variations. Certainly much wider than for a single species like the lion.

      Delete
    58. Size is not an issue - things grow. Number? You have to make a decision whether there are multiple animals are involved. Not an easy task and of course there are misidentifications and real reports that are not 100% accurate.

      Your job on the other hand is easy - all misidentifications and hoaxes.

  11. After all the other comments my input is probably moot, but here it is anyway. At first sight it would seem to show all the classic form characteristics of a Nessie i. e. long neck, small head and hump. However, like the Shiels pic, to me anyway, it just doesn't look right, and I dont get the '"feel" that it is genuine and I slip into the "to good to be true" ravine. If it was truly a real pic and the person who took it was acting in good faith, honest and sincere he or she would have come forward declaring as such. The tired old excuse of the fear of ridicule just doesn't cut it in these modern times. Maybe in the 1930s when the phenomenom first came to public attention, but not after 80 years. As an aside comment on the second hump, if the pic were genuine, I would offer an interpretation of the tail turned off to the side. In total, it has fake writtien all over it.

  21. I tried out the fotoforensics website and it didn't detect that I had saved the same JPEG file 3 times (closing and opening it again), which should have lead to a loss in quality. Although Photoshop will leave it's mark on a JPEG, I use it regularly to adjust colour, contrast etc, so it is not necessarily being used to take and event, so to speak. As far as I know, jpegs do not save information regarding the steps taken in Photoshop, although other file types can do this.
    Cloning can be obvious, and is a bit of a skill to acquire, although when done properly it can be very hard to detect.
    Other parameters can lead to a lower JPEG quality than manipulation, such as choosing a smaller JPEG in camera. I'm not sure there's any easy answer to finding a fraud, only pixel level analysis by an expert, or more sophisticated software than the average person might have access to.

    ReplyDelete
  22. Martin, PS doesn't "resave" jpg images if there are no changes to them, it doesn't overwrite the original file if it doesn't have to. So opening it and resaving it several times (under different names)might result in a simple duplication of the file. You would need to alter it in some way (even change the compression quality) to persuade PS to re encode the file.

    ReplyDelete
  23. Les, every time you open and resave a JPEG, it diminishes in quality. The JPEG is a compressed format, containing only a portion of the original image data. Various parameters are set as a JPEG is made in camera, such as sharpness, white balance, noise reduction and exposure. All latitude on such settings is data 'thrown away'. These parameters cannot be altered once set, and so a great deal of information is lost, hence the compression from approx 100mb to less than 10, more likely around 5 for my camera. Every time the JPEG is opened and resaved, it is decompressed and recompressed. The more one does this, there more chance that the process will lead to errors, as no image compression is perfect. Ie., we cannot just have our pristine image back from our JPEG - it's a pretty good approximation, but if it were perfect then there would not be a need for much larger uncompressed versions. Artifacts and colour distortions built up over several saves, as the errors from our approximations build up. The easiest way to replicate this was to take a picture and rotate it many times in windows xp picture viewer, and watch it go all hallucinogenic.
    Anyhow, I did make changes to the image every time I opened it in PS. Not to mention the fact that if one wanted to fake an image in 100% quality it could be done in uncompressed form from a raw or tiff file, and then saved.
    I think the forensics of photography is a bit of an art and a science, and I'm sure I only know the very basics of where to begin.

    ReplyDelete
  24. I think you missed the point I was making Martin. I'm not commenting on how jpg compression works but pointing out that in the example you gave at the start of your paragraph - " I had saved the same JPEG file 3 times (closing and opening it again)" This wouldn't result in any reduction in quality. If you simply open a jpg image and then select "save" Photoshop does not actually recompress or resave it. If anyone tests this they will find the opposite of what you describe. The quality will not reduce even If you do this 1000 times because Photoshop will not recompress or overwrite the original file if you haven't changed it. You explain later that you did test this by rotating the image, but your first description of how to test jpg loses confusing because anyone trying what you said won't see the reduction in quality you promise.

    1. Apologies for the confusion Les, PS does not allow a save if there has been no alterations, so one would not be able to do what you thought I was suggesting once or even 1000 times. I hope I've cleared that up now. But, point still being, fotoforensics did not pick up any additional jpeg compression.

      And regarding the point as to how a jpeg 'works', forgive me if I was teaching you to suck eggs, but I thought a run down of the basic mechanics of what was taking place would help explain how you had possibly misunderstood me.

      Rotating the image was not a test of this, it was just an easy way for people with windows XP to view this in action.

      I hope this clears things up.

      Delete
  25. Thanks for clarifying that Martin. I can also explain why Fotofornsics didn't detect the loss in quality from your resaves as you mention you expected it to in your previous post. GB also gets this wrong in the above article - the paragraph titled "jpg Quality". Just to refresh, GB suggests the fact a control (unaltered) picture from the same camera has the same (85%) jpg quality as the "Nessie" picture suggests that the Nessie picture has not been resaved, as would result in an associated quality loss.

    Fotoforensics jpg quality estimate is not concerned with asthetic quality, its looking at the quantisation table in the file. This is set by the quality level selected at the time the image was saved. No matter how many times its been saved or how poor the quality is. Keep in mind that Photoshop has a quality selection from 1 - 12 and Fotoforensics measures in percentages If you open a jpg in Photoshop then save it at quality 1, that is very poor quality. Fotoforensics will measure it as somewhere under 30% I would guess. If you then load this image back into Photoshop and save it at quality level 12, Fotoforensic will measure that at 100% jpg quality since it reads the quantisation table as 100% Try it yourselves, it will only take a minute.

    ReplyDelete
  26. Thanks for that Les. It seems that particular measurement is not an indicator of any fakery, or anything really other than the absolute JPEG compression quality. Back to the drawing board....

  28. To all those non-believers out there -
    back in the 1970s I worked with a man from Scotland,
    his mother still had the house very near the Loch,
    and her kitchen window overlooked it.
    While doing dishes, she quite often saw the 'monster',
    at least this is what the son told me. He also said
    the townspeople know it is there, so all the fighting
    over photos, etc. is just pointless.
    The Loch Ness Monster exists!
