Tell me which tog or MUA would take the worst model they can find and then pay them lots of cash, and then use those images in his porty?
You would be surprized.
Bottom line, I have never seen a successful model that did not look good when ready to shoot.
Most people look "hot" just before shooting, or when "ready to shoot" that is the main idea. To get everything as flawless as possible, so again I disagree :)
Ive seen some "hot" models, some, are naturally beautiful, others if they not Photoshopped or professionally done up, they simply not that "hot" - would someone still pay plenty of cash for them. I think so :) Its about the end result.
Also, I think peoples versions of "hot" differs, quite drastically in some cases.
