retouching/airbrushing/photoshopping....what's the difference for heavens sake. There's absolutely nothing new going on these days, it's just different technology, that's all.
Agreed. There's nothing new as far as the end result is concerned, but I think the point is that the versatility of Photoshop retouching lowers the need for expertise on the part of the photographer. Photoshop retouching is much cheaper than airbrushing etc. and it can do things to an image that just weren't possible, (at least not at an affordable cost) in the past. There's no such thing as a "re-shoot" these days.
