So, as it turns out, I have to show a portfolio of advertisement photos in a few days to a possible client. In order to do so, I am hoping for some advice. Here are the questions I would like answered: 1. I know the old standby of 11x17 white foamboard with 10x13 or 8x10's mounted on it, in a leather case. For monetary reasons, and since this is sort of a one time thing, would a small 3 ring binder with 5x7 photos mounted on cardstock be acceptable? 2. How many photos? Any other advice you can offer would be helpful. It is a big client. Thanks!
