Can you be more specific about what the "oddities" are? What exactly does the "forensic software" do?
No problem. If you look at the colored version, you can see the drastic difference between the face and the the rest of the photo, color wise. If you look closer you can actually see the outline of the face, which to me looks to have been a cut n paste job.
So I ran it through forensic software with an Error Level Analysis (ELA) feature.
What ELA does is pin point segments that contain different compression levels to reveal a higher error level potential than the rest of an image based on contrast. An altered image using ELA will be fairly uniform in contrast throughout. If you're evaluating skin, any edge that has skin next to black/dark pixels will reveal a higher error level potential. All similar edges should be the same brightness in an ELA image.
If you look at the ELA imaging results here, you can see the highest error levels are around the face. You can also see a black line that separates the head from the body. That's the skin next to darker pixels I was talking about, which is indicative of an alteration. When a photo is converter to black & white, it's much harder to detect the difference in compression ratios of an altered image with the ELA imaging analysis. You'd have to use another means.
If you run ELA on an unaltered color photo, the compression should be uniform. But altered images are unlikely to have the same characteristics. For example, if you add an object from one source, such as a face from another photo, and paste onto a body in another photo, the characteristics won't match due to the millions of tiny differences within the pixels themselves, such as lighting, contrast, exposure, noise, etc.
So the ELA focuses on compression to detect those differences. The best example can be seen in the last square (the blue image). If the photo was unaltered, that blue filter would be uniform throughout. But it's not. And the only place it's drastically different happens to be in the facial area. Now if there were any questions as to the authenticity concerning this photo, where would you expect likely alterations be? The facial area.
So what is the chance that the higher error levels around the face are indicative of an alteration? But even without all the compression differences, the black line separating the head from the body is still an abnormal anomaly on its own. There's no reason for a break to exist between the head and body. Whether or not it's the real head of that body doesn't matter, because at some point it seems to have been altered for that anomaly to occur.
I find similar anomalies in Mortgage documents, where banks or trustees might copy & paste signatures. You'd be amazed how many Mortgage documents are altered. Your Deed probably isn't the original you signed at closing. If you examine all your signatures up close you'll find at least 1 with the some type of anomaly. Most times you won't even see them with the naked eye.
Here's an example of a Deed I examined with an unnatural break between the signature line and signature.

Anyway, that's the best I can explain it. Hope it helps.
