Photoshopping Ads

I personally think Photoshop is an essential tool in the world of advertising. I think the public has a pre conceived notion that all models are photoshopped, so they realistically don't expect people to actually look like that. Photoshop can be used in a plethora of ways, not just to make the female model population look more attractive than they already are. It is used as an art tool as well, to create things that can not be photographed.
