lots of guys have an average exposure, but the lighting is too hot on the girl, so highlight areas have lost detail---this is especially true with high rez cameras and shooting jpg.

best to use a camera body which has a very long tonal scale and expose for skin highlights, then adjust gamma, then balance levels.

nikon can visually show highlights that you have blown out with the histogram---i don't know if canon has this feature.
