Weird and Wacky Engineering

Is it real, or is it Photoshopped?

The first photographic image was made with a camera obscura by Joseph Nicephore Niepce in 1827. By the mid-1850s, photography was everywhere. Somewhere around this time, the phrase "The camera never lies" was born.

The idea was that, before photography, the main medium for capturing images was painting, but painting is a very subjective thing and the artist can easily affect the way things look. By comparison, a photograph was regarded as being totally objective – it was considered to reflect the absolute reality of a moment in time. Based on this, it was widely believed that a camera (or a photo) was not able to lie.

Of course, people being what they are, it wasn't long before folks began to use photographs to "experiment with the truth." One classic case is known as the Cottingley Fairies, which involved five photographs taken by 16-year-old Elsie Wright and 10-year-0ld Frances Griffiths in England in 1917. One of these images is shown below.


Sir Arthur Ignatius Conan Doyle, creator of the Sherlock Homes stories, was very enthusiastic about these photographs and interpreted them as clear and visible evidence of psychic phenomena (actually he was somewhat gullible, and he interpreted most things as evidence of psychic phenomena).

These days, of course, we have all sorts of incredibly sophisticated tools at our disposal, both to create fake images and to detect them. In my recent The Ancient Order of Froth Blowers blog, for example, I was waffling on about the recent Transit of Venus. Someone commented about a rather cool photograph showing a plane traversing the sun at just the right time as shown below:


The jury is still out on this one. I've seen lots of discussions covering little nuances about this image – most people seem to think it's genuine, but some commentators aren’t so sure.

Fortunately, in addition to my incredible good looks and amazing sense of fashion, I have been blessed with an eagle eye and a razor-sharp intellect, so 99.9999% of the time I can tell at a glance whether an image is genuine or if it's been "Photoshopped." Take the following for example:


There is no doubt in my mind that this is 100% true-to-life. This was obviously taken in the swimming pool at our last family get-together. I would recognize my mother-in-law and father-in-law anywhere!

I had planned on getting out my long telephoto lens to photograph the Venus transit. Unfortunately, as usual in this part of the country, the clouds got in my way. To console myself, I decided that I could just as easily take a picture of the sun and put a black dot on it in my computer. Near the end of the transit, however, there was enough of a break in the clouds allowing some folks here to see it, but I had given up already.

You may be wrong about the shark and dinosaur, unless your relatives spend time in the Pacific Northwest. I spotted the pair swimming near the old Trojan Nuclear plant on the Columbia river last weekend.

Ah Duane... it's not the size of your telephoto lens ... it's what you do with it that counts! :-)

Hi Max, perhaps you need to have a look at Fotoforensics, as espoused by blogger Boy on a bike:

Then again that may not be as much fun as guessing! ;-)

Wow -- this is very interesting -- I'm up to my ears at the moment -- but I would love to see the results of running this analysis on the three images in my blog above ...

I used the FotoForensics website on the sun photo and can't really decide is it's real or not. Based on how I interpreted what the tool shows, the plane might have been added in later, but I'm really no more sure one way or another than I was before. I think it takes better trained eyes than mine.

I am neither an astronomical / telescope expert nor do I have any experience with Photoshop, so I am counting on those who are to correct me and my fading memory, BUT...

I was lucky enough to have a friend in an astronomy club take me to a place where about 50 people were gathered, with all types of different equipment: reflecting telescopes, digital cameras, pinhole projectors... Looking through lots of different things, I saw Venus in many different positions on the disk of the sun, but when I used a simple filter (i.e. untransposed by optics), I'm pretty sure it appeared much lower.

If I am correct about that, what this photo shows is an uninverted jet passing before an inverted image of the transit - not possible without taking the images separately.

Uh oh, hang on... perhaps if it were taken from the southern hemisphere? Ah well. I observed from Western NY State.

Probably 18 or more years ago I saw an ad for a photo editing program that showed all kinds of changes that could be made. And after the changes were made using the program, they then produced a negative that included all of the changes.
Prior to that, some folks were quite good at "compositing", which was printing things from multiple negatives to produce one composite photograph. Also, consider the retouching that was done to portraits for many years. So even then photographs were being modified.
Presently there is probably no limit to what can be put into a "photograph".
So we can say that a picture usually lies.
