No it isn't... After all warping and pasting will bring a picture beyond recognition.

Another issue here that is relevent in all of these galleries is that, any opinions here are likely to be those from "artists"... be they digital or manual (photo or rendered).

I suspect that the majority of others would not accept "any altered image as a photograph" so I stand by many of the comments above.

This then may make artists say.. "who cares what they think"?
But whether we like it or not; non artist opinion does shape much of the world around us.
A "photograph" is a specific name that is associated with expected imagery. If this is baulked too much you'll loose your target audience as already mentioned above (Misha883).
I have done the apprenticeship in darkrooms to the point of mixing chemicals (a long suffering job). In many ways Photoshop is replicating the dark room but not all of it. Who wants to replicate the wait, and the chemicals?

As artists we should be responsible; and our "out bursts" controlled.
"Anything goes" is an innocent enough phrase, but it leaves the door open for the "charlatan" who will show what "anything goes" realy means. The artist community gets damaged yet again.
