Lets expand that definition a bit then. Lets say that I use a flash in a photo, does the result become a "photo" or "artwork based on photo" in your definition?

Lets expand that definition a bit then. Lets say that I use a flash in a photo, does the result become a "photo" or "artwork based on photo" in your definition? I'm altering the light received by the camera. What about a neutral-density filter? polarizing filter? So if I use a lens with a higher rate of chromatic aberration then say a super expensive lens with less chromatic aberration, does the photo I take become "artwork based on the photo" as its altering the light received by the camera more.
