I recently came across this photograph which looks extraordinarily suspect:
Can the Photo.SE community determine if it is fake? I've played with the Gamma, Brightness, and other levels but cannot find conclusive artifacts. If the image is determined to be doctored, what specific signs give it away?
Note that the Photo.SE question for the general case of determining if a photo is real or faked has a comment by a high-rep user inviting one to post suspect photos as new questions.
I suspect that this image may be faked because: As fun as Pareidolia is, in this particular case there is no suggestion of a face but rather a very accurate rendition of a dog. The sizes, perspective, and even the shading of the wood suggest a dog. It is true that the wood may have been altered and not the digital image, however, that might account for the shading but not the knots in the wood.
