Hi Stephen,
I do actually own lots of photo editing software and have actually beta tested several at the university.
I just believe in getting it right the first time !!! But unfortunately levelling I can't !
I'm a member of a couple camera clubs and several photographic societies and love bringing this subject up as it always gets a good debate going. Believe it or not most people for edited images within competitions are the ones in their retirement obviously because of the time they must have, where as the younger generation( thats me early 40's) its what you see is what you get.
But the whole point is the camera was invented to capture the moment and freeze a moment in time as the eye see's it.
Anyway its just my opinion which does'nt always mean a lot
All the best Haydn
