Hello, Ive been taking some shots of my female friends that I would like to put together in a portfolio. I had some shots blown up to fit an old portfolio case i had for a modeling portfolio, but they made them too large, and I noticed the portfolio case dimensions I had would force me to crop all photos taken from the cameras normal dimensions. The photos they blew up to 10"x15" (25.5x38.2 CM), I was wondering what the most common picture size is for displaying a portfolio? (i've seen a lot of 11x14 online-but those dimensions would make me crop the pictures). I'm using a Canon EOS 300 - Normal Reflex (Spain) Any suggestions would be greatly appreciated.
