I was recently shopping for paper and found the following item: "Ilford Multigrade IV RC Deluxe MGD.44M Black & White Variable Contrast Paper (3.5 x 5' Roll, Pearl, 100 Sheets)" http://www.bhphotovideo.com/c/produc...IV_RC_DLX.html
I have never heard of photographic paper being sold on a roll, and can't find any information about this on Ilford's website or anywhere else. I gather that this means just what it implies: that the paper is on a roll rather than individual sheets. My only question is whether the paper is perforated or otherwise demarcated at regular intervals? Or do you you have to measure it yourself as you go?
