I am replying here, because I don't have enough posts to reply in the Glamour forum.
Now, I am not a professional photographer, or anything near it. In fact, I am just starting college for photography in August, so I am an amateur in every aspect.
But I think that you shouldn't necessarily try to hide or photoshop your wife's "imperfections". Those "imperfections" are what make people unique. I know that a lot of people, especially when in their later years (women, probably even more so) find it hard to look at age discrepancies and flaws as beauty, but what else are they? Just because the majority of people are attracted to certain things doesn't mean that somebody without those characteristics is any less amazing.
I say that, instead of hiding and shadowing and photoshoping... you should try to embrace those imperfections and care not for the opinions of naysayers. Just because somebody may be more "flabby" than someone else, or too skinny even, that doesn't mean that it is a bad thing. I say embellish those features and come to terms with them. Confidence shines through imagery far more than plastic surgery in my opinion. And when I get my Bachelor of Fine Arts degree and go on to "bigger and better" things, I don't plan on hiding physical features, but rather, bringing out people's confidence and courage from inside.
I love looking at images of people (and all other things) that are less than perfect. Perfection is only a perception. Everything has great beauty to it. I say embrace it whole-heartedly.
I apologize for my extended post.
