in your example photograph, I would point out that it is in a studio, with perfect lightling composition and posing. I would also point out that the photograph has likely been analyzed and enhanced for publication / reproduction. Few people realize that most of the photographs they see are the real thing, without some editing / cropping / lighting enhancement and photoshopping ( intensifying certain attributes, removing others ). Perhaps the better answer to your question is ... do such perfect examples exist in the real world ? Yes, but they are few and far between, and more a product of genetics than a photographer's lens. Always remember to ask who profits from such a photograph, and that profit is what it is all about. Doesn't anyone notice that there are no pictures (or more accurately, waaaay fewer pictures of average, non-beautiful people featured in publicly circulated photographs / magazines / websites ? I have a good friend who is a doctor, and his comment says it all for me ... there is almost NO ONE who looks good naked, and I have seen them all ... )
