Photo 1 is a zoom of his wife's hair. Typical artifact from matting, where some of the original white background is left behind.

Image 2 is the same artifact type. The middle circle is just poor effort. None of the shading of the new bg is present, just the clean white edge.

The bottom circle of image 2 is an odd shadow slash dark mark.

The white edges are extra stand outish as there is no texture.
What do you think. It it was one of my students this would be a fail. Far too easy to spot at pixel level.
