How many pictures should be in a portfolio? What should I carry my pictures in? I am considering getting a binder and putting my photos in sheet protectors and carrying them that way. I understand that 8x10 is standard portfolio size, however some people here on this board seem think otherwise, and I have no reason to argue because of their years of experience. I have ordered a paper cutter to cut my 8.5x11's down to 8x10. Hopefully that doesn't take to much practise, I don't want to ruin too many pictures in the meanwhile.
