If Your Message Is Good, Why Lie?

A First Principle is that two things can be true at the same time.

I can be fat and I can be old. Both are true, at the same time.

Next, who are you going to believe, me or your lying eyes?

50 years ago, a picture was worth a thousand words, and it could communicate truth where words could lie.

This was never “true”, it was just believed. Photographers have been doing “touch up” of photos since the earliest days. Some of that involved painting directly on the plates, other times it was more extensive.

It got to the point where people were building composite photographs, showing things that did not exist.

A flatboat with eight light-skinned men floats toward us down a wide river in this horizontal painting. The boat nearly spans the width of the composition and has low sides and a shallowly arched, low cabin upon which the men gather. At the center, a man with dark hair and wearing light blue trousers and a pink shirt dances with one foot and both arms raised. To our right a seated musician plays a fiddle, and to our left a smiling man holds up a metal pot and strikes the flat bottom with the back of his fingers. The remaining men sit or recline around the musicians and dancing man, some looking toward the dancer and two looking out at us. Bedrolls and animal skins are stored in the cabin below. The olive-green surface of the river is streaked with pale blue. The horizon line comes about a third of the way up the composition. The trees and riverbanks in the distance are hazy beneath a watery blue sky.

This painting caught my eye when I saw it in the National Gallery. I took a picture of it, then had a correspondence with the Gallery because I could not find it in their gallery.

The reason is that the painting doesn’t belong to the Gallery, so it is not in their gallery. This was explained to me, and then the very nice lady explained that this painting was a “fake”.

It was fake in that this particular scene never took place. This is not the artist adjusting the setting or anything like that. The artist was known to make quick sketches of interesting people doing interesting things. Or just interesting things. He would then create a composite image from those sketches and, from that image, paint something that wasn’t “real” but it wasn’t truly fake, either.

I expressed it as “The Photoshop of 1846”, to which she agreed.

We have become much more sophisticated. We even have a word for those manipulated and faked images, they are “Photoshopped”.

We see, and most of us recognize, the manipulations that are used on the cover of magazines. We notice it when things “just don’t look right”.

One famous example was the Vogue cover featuring Cindy Crawford. The magazine had “erased” her mole. She got upset and said that her mole was part of who she was.

I spent years working on Computer Graphics, making very high-quality renderings with no real images involved. At one point, one of my teammates was giving a presentation to some brass. He was talking about how we had managed to make our trees look more realistic.

As he was speaking, he was clicking through different images of a real place. Well, the digital elevation map, as we rendered it, with our fake trees planted where the trees were in the real location.

Not a single pixel of the images shown was real. It was all computer-generated images.

After about 15 minutes of the talk, somebody with brass on his shoulders stood up and said something like: Enough, I’ve been to there, I know what it looks like, I want to see your images.

Our fake images looked enough like the real thing that an intelligent guy, with stars on his shoulders, that he was looking at real images.

Those images took days to model, weeks of programming, hours per image to render.

Today, you can ask an “AI” to create an image for you, refine it, then push it out as real. The image will often be a composite of many real images or sub-images.

Photoshop actually has “smart fill” and “smart erase” that are designed to use AI to “seamlessly” fill areas of an image or erase areas of an image.

What 20 years ago took a team months to accomplish, a troll on a media team can accomplish in minutes.

It has gotten to the point where people can create an AI movie by creating the proper prompts.

Some AI-generated images are easy to detect. A Tuesday Tune I posted had visuals created by AI. Not my doing. Some guns were absolutely mind-blowing. The cylinders with 8 chambers, each chamber looking like a keyhole. It was fun, in its obvious errors.

We had the period of time when people were getting multiple rows of teeth, or hands with six fingers, or a dozen other “standard” errors. It was fun to pick out, or down right terrifying, depending on your view point.

Can we trust our eyes when we watch a video? We know some ways that things are faked. But this new technology is going to get better, harder to detect. We are already long past, “Pictures, or it didn’t happen”. We are rapidly moving past, “Video, or it didn’t happen.”

  1. in todays world even images taken in real time, un manipulated un touched are labeled fake by a few and it becomes gospel truth.. “social media” has distorted everything it touches.
    truth is labeled lie and lies are labeled truth. having fun yet??

    I remember reading, years ago, a statement about images as evidence. It said that images are not evidence; what is evidence is the sworn statement of the photographer that the image is real, created by him, and accurately represents the scene at the time.
    That test gets tougher and it is clearly easier to cheat now, but the concept remains valid.

    On the picture at the top: the file name suggests the entire crowd is CGI, and the reality is that the scene was empty. That’s what the circled reflections seem to tell us. Is that what I’m supposed to conclude?

      When I was working with a local PD as they transitioned to digital, one of the requirements was to make sure that the image had not been modified.

      As we pulled an image from the camera, we generated an MD5 and that was recorded.

      The photographer could then testify that he had a printed sheet of MD5 sums and file names. That this particular image being presented currently had an MD5 sum that matched.

      This allowed the photographer to testify to an unmodified image.

      As for the takeaway from the image in question? I don’t know.

      There are a number of images that look questionable to me. I found a good image with the questionable areas circled/marked. Make of it what you will.

      Finally, there have been some videos posted from people at the event. I’ve not seen any of them

    Its worth remembering that deceptions can be done even without touching up of photographs. As I recall, FDR’s image was carefully curated by the press so as to prevent the public from realizing what the journalists around him all knew; that he was crippled and couldn’t walk. They didn’t need photoshop for this, merely to only publish pictures that suggested what they wanted to suggest.

    A lot of people get worked up about photo irregularities like this from time to time but I think a large amount of it just arises from not actually looking closely at photos and videos in general. A very long lens can make a shot like this, and take a fairly large but not huge crowd and give the feeling of a sea of people, and make it sort of look like its up against the plane when in fact it must be quite a distance away.

    This isn’t to say photoshop editing and touching up doesn’t occur, in some cases it obviously does (Biden hand clipping in front of microphone, anyone remember?), but in a lot of cases it isn’t necessary and a scene can be portrayed very differently by different photographers and different equipment. Remember the Trump assassination views, some (long lens, far out) shots make it practically look like the SS Snipers are looming right over Trump, shorter lens shots from closer to the podium leave the snipers entirely out of view.

    And this is even before we get to weird effects from compression and denoising, which are even worse in video and throw in all sorts of bizarre effects when you study them closely.
