I just purchased a zenfolio account and had a interesting conversation with my wife. I was showing her how I can restrict what products/prints people purchase for different galleries. Since I crop all my family/friends/wedding images to 4x6, I was considering removing the options to purchase images at different sizes (such as 5x7). This way I can restrict how my images are cropped and not have to worry about some random person doing a bad crop job on my photos. My wife's argument is that she REALLY enjoys the freedom of selecting, say a 5x7 print, if that's what she needs/wants. If she already has found a beautiful frame for an image, it's a hassle to be restricted to just 4x6 prints... Mind you, I'm not trying to make a living off my photography and I'm not a pro's pro... So the idea of someone taking a 4x6 and cropping off the sides a bit to make it a 5x7 isn't that scary... but that control is an issue... some yahoo taking a 4x6 and cropping it square (say a 8x8) will require THEM NOT ME making the artistic decision of how the print comes out... THOUGHTS?
