Hmm got drawn into the pro v am topic on a different site....
1. a pro photographer may in fact earn all of his money shooting engineering parts, this does not make them the best or even a good model photographer!
2. there are 'amateur' photographers who have very high earning day jobs, so do model shooting as a hobby/second income and they are well respected and admired.
3. a pro model may be someone striving to earn an income from modelling, this does not make them the best in every genre. (I met an excellent model last week, who will only work part-time around her day job so she can pick an choose who she works with and she was very professional)
4. Someone once wrote, that many professions only earn a portion of income from a particular activity, but that doesn't mean they are not qualified or professional!
Me I am a self professed amateur photographer, never earned a penny from any form of photography

and probably never will. But that doesn't mean I don't spend money kit, props (lots of props/furntiture) and hiring models (oh yes good {NB not a reference to my photography technical skills} amateurs don't blag TFP, we know who we want to shoot, book them and PAY them)....
But then we will all have different views, opinions and ethics, but isn't that part of the fun of a varied world.... you all have fun Stu
