Thanks for bringing up the aspect ratio issue. What would you reccommend to correct this issue?
The most effective way would be to supply them with prints, not CDs. When they want a different size, they have to come to you.
The 'most effective way' might not be the 'best' way though.
If you want to give them CDs, you could make a crop of each picture for each crop they might want, and label them clearly. More work, but you could always factor it into your prices.
When you give them a CD, you're basically leaving them in charge of the printing. 80% of the time, that's probably fine, but there IS the other 20% (maybe it's actually much more than that...?) who don't know the difference between 2:3 and 4:5.
No matter what, some people will try to rip you off. Even supplying them with prints, I can guarantee you that some people will just buy the cheapest ones you sell and scan them.
I can't even remember how many people have asked me to scan other peoples prints for them so that they can make more prints since they know I am a photographer and have "a good scanner". Or asked me to scan wallet size proofs and give them 8x10 prints of them...
They don't even care that it would look like crap if I actually did it. Those are the people you will be dealing with if you don't charge enough to scare them away.
