There's a fine line when it comes to retouching. Either not enough or way overboard going into that "plastic" look. My philosphy is to keep it as natural as possible while at the same time putting in the work to enhance each person's true beauty, not covering it up. Every person has flaws and by using today's most sophisticated editing software I try and miminize those flaws or completely remove them. Bad skin, scars, tan lines, stretchmarks, wrinkles, etc...basically I've seen and fixed it all. So don't let the fact that your not perfect since noone is, stop you from doing something fun, exhilerating and getting the images you deserve.
