I am getting together some B/W prints that I hope to frame and present. The prints are of varying sizes from small scale contact prints to larger 12 x 16 inch prints. I have a framer that I will be using and clearly I can get some good advice from him but I want to do my work in order to get the very best size of frame and matt to suit each print. To save me wading through endless websites which I have started doing (many which are simply commercial companies selling frames), does anyone know any good websites or online advice on frame and matt sizes? Many of my prints are square and I tend to like a wider matt but I want to really put some thought to this, to research the best frame and matt size and proportions in order to best bring out each shot. Clearly much of this is personal taste but I really welcome any thoughts on this. Many thanks for your help.
