While photographing models, I've been fortunate to learn a fair bit regarding the basics of portrait photography. As photographers, we always try to make people look their best. We're not plastic surgeons in any way (though it would be good if we were), but we use the aid of lighting, posing, composition and even the liquify tool in Photoshop to make our clients look their best. And one of the best techniques to master is how to make our subjects look slimmer. This is particularly an issue in Western countries where more 'overweight' subjects are more commonly encountered.
