How do you know when something is photoshopped and you shouldn't use it for reference?
Like I can see the navicular and cuneiform bones here, do I assume it's not shopped?
The skin texture also looks kinds weird and airbrushed but it may be the camera quality or maybe makeup.

Is there a check list or sure fire way to know?
Some stuff like bones and anatomy messed up is easy to know but some other things aren't.
