I'm skeptical of this claim about that old image of Vic being Photoshopped. I'm just not seeing it.
There's a strategy I use for visual art where I take an image and then equalize each channel in varying colorspaces to generate neat false-color versions of a photo. One of the strengths of this strategy is that it occasionally makes inconsistencies very plain. This analysis is not showing anything atypical in the image. I don't find the error-level analyses very persuasive here.
I've attached a few different colorspaces to show the kind of details this equalization technique pulls out of the image. Left to right, these colorspaces are xyY, HSI, RGB, YUV.
