An excellent image mysnapz!

As for the question,
I tend to agree with the others, the photos in this picture
were rather used as a sort of "raw material",
e.g. like one would use a photo textures in a 3D-software.

I would set the limit about what I would call a photo:

1. If "recording light" is still the main purpose.
2. If all that I did in postwork could have been done in a real world darkroom as well.

But that's just me and my 2 cents. ;-)
