I just read the last thread and being a professional photographer, however I'm no longer a member of the AIPP (was in the past and win an award or two - not blowing my trumpet but trying to give background)
Some people think that because I might charge less, means I'm not as an experienced photographer etc. so those that charge a lot sometimes aren't good and sometimes they are brilliant.
Personally I think you should pay for the personalised style and personality of the person capturing your memories.
The actual cost of getting prints is expensive as are canvas's. So it does eat into the total figure earned.
It does sound a little high priced but if he is an established photographer then it could be justified.
Basically if a wedding photographer charges between $3-6k they really would actually make around $50 an hr after you take out travel costs, insurances, actual editing hours and you are paying for their 'style'
You can report or contact the AIPP - Australian institute of professional photographers and they will guide you if the photographer is a member, as to what you can do.
Part of being a member with them is having to prove your quality and service offered. This includes business practices.
Otherwise I hope your picture was with worth it memory wise.
