hi lumierephoto and welcome to
RP.
the fashion/glamor industry is one of exacting detail and high quality. and when you're talking detail, one of the areas of most concern is skin. natural skin has 'texture', the impression of being 3 dimensional with highs and lows and roughness and so on. skin, to the casual viewer, seems smooth. but, in fact it's not. skin has pores, pits, highs, lows and so on that make it what it is. when you erase these or paint over them or clone them out, the skin no longer looks realistic and believable. think of a model that wears too much makeup. it covers all this texture with foundation or pancake (or whatever) and you lose all the skin detail and it just looks like too much makeup. the trick with makeup is to make it look natural while also giving the illusion of something incredible or enhancing. the same trick exists in retouching. too much smoothing, smudging, cloning, etc. and the image no longer looks natural.
if that's the desired look, then that's fine, but most glam magazines i've seen arent looking for the kabuki (sp?) look (very heavy makeup). they want models that look 'glamourous' but natural.
take a look at the lips in your image. there are highs and lows and midtones. then look at the skin in a given area. it's all the same. there are no pores, no differences, no detail (or not much). so the model looks 'pasty face'...as if she were wearing a ton of foundation.
now, i dont mind the lighting, the highs in the upper left but the pasty face is a dead give-away that this is a retouch. the trick is to make folks think there has been no retouching where there has been some or even a lot. glamor retouching is all about the illusion and enhancing without letting the audience know how the magician did his trick
there are a lot of threads on
RP here that deal with retouching skin. i think there are a couple going now in the first forum. have a look around. you'll find a lot of opinions and techniques and help.
