Thanks for all your answers. I never suggested that we should push for a new paper size. As I explained, I've accomodated the current paper sizes by printing inside the paper, printing the entire image. My main point is that I think photographers should compose in the camera and that paper shapes should not interfere with original composition. If you want to compose square pictures, use a 6x6cm camera. If you like the 3x4 ratio, use a camera that shows you that. I've chosen the 1.5:1 ratio, so I work in 35mm or 6x9cm formats. It's that simple. I do actually cut down all my 16x20 paper to 15x20 so I can print 10x15" images with equal borders. (I also get some 1" wide test strips as a by product)(posted 8494 days ago)Tom
