I was having a discussion the other day about my PP techniques and it was suggested that what I'm doing is actually digitally 'painting' over my original by creating and blending layers, pushing colours etc. I don't 'change the light,' move trees about or add skies etc, what you see is what I experienced, but this may be different to what was optically captured on film or sensor.
Haven't a problem with that, but was wondering if there was an established point at which a photographic processing session officially turns into a digital painting, in a similar way to how some painters photograph the scene and then project the slide onto a canvas.
Many thanks for your thoughts.
