Nah, that's gotta be trimmed or very subtly 'shopped ....
[gets ruler, measure screen in six points on each picture, finds perfect match] ... holy malarky, I think my brain just got discombobulated!

There actually is a slight trimming; while the top portions of the image are the same the bottom portion has been altered. About where the first series of pillars meets that floor two or three pixels have been removed in a line across the second image. The images are the same size though, so on the second image you can actually see more of the structure at the bottom. The images are also slightly out of line; the second image is several pixels higher than the first image.
Imagine a two parallel slanted lines, then remove a portion from one line and mate the ends vertically, extending the bottom of the line by the same amount. What you end up with is two lines that are still parallel, but the top portion of one is farther over in the direction of the tilt. It is amazing our brains can detect such subtle manipulations, but it is not completely brain-based. |

Well, this may make it even more confusing. I drew a slanted line and attached the picture twice (under different names.) Do the lines look parallel, or is the one on the right tilted more?

The perspective matters, too....and i think the colors do a little bit to them as well.

does the image change if you put the whole thing on a treadmill, though?

The coloring of the sky looks darker to me. I have to get off this thread, my brain hurts. Think I'll go post in Ducks headache thread.

Seems to me the true test would be to reverse the two original images and see if you still get the same effect.

As I said, the shifting is very subtle and it would be difficult to see it simply by overlaying a semi-transparent image over the other. A better way is to overlay the image using the "Difference" layer quality; this method of overlay means that pixels nearly identical between the two images are made dark, while increasingly dissimilar pixels are lighter in color.
The image was compressed when it was put online, and many compression methods will leave artifacts around the edges of sharp color transitions. What would be expected from an identical image overlayed with the same compression method would be a very faint outline of sharp color transitions over an almost completely black image. Instead we can see a sharp transition between mostly black to bright outlines, indicating the images do not match up along these transitions (where the differences are more dramatic). If the entire image was this way it would indicate the overlay was out of alignment; the fact that only sections of the image do not match suggests tampering. Once you know where to look you can see the change by alternating full opacity layers. The first image is with the overlay matched to the bottom section. The second image has the overlay shifted down to align with the upper section. The second image shows a suggestion of another cutting about 1/3 of the way from the top, look for the horizontal bright pixels. . |
