My point was the same - although I went on to say that the title of 'true Photograph' is ambiguous.

Are level adjustments acceptable?
What about grey-scaling?
Emulating Infra-Red via post-work?

How about removing a logo from a building?
Smoothing a figures complexion?
Removing clouds to improve composition?

My point is, there's really no way to draw a line in the sand. I for one would not be comfortable defining what is and isn't a photograph based on the post work it has recieved.

If we can hit that bullseye, the rest of the dominos will fall like a house of cards...checkmate!
