I have been shooting mostly b & w 35mm and scanning on a Minolta 5400 and printing on a Epson R2400 with decent results. I have always considered buying a Pentax 67 outfit for landscape work but every time I think about spending the money, I back off. I think I will have to buy a new film scanner to work with larger negatives. I can get pretty good results printing up to 12" x 18" depending on subject and film used (trying some EFKE 25 now) yet people talk about the big difference in moving up to medium and larger formats. I don't develop my own film since I barely get time for my hobby. I send my film to a pro lab so the ease of working with larger negatives means nothing to me. I like spending time shooting, printing and working on my images in photoshop. Is there any real difference in image quality for smaller prints sized 8 x 10 comparing 35mm to medium format? I also noticed many people who sell there work here are mostly selling smaller sized prints. Doesn't that make the whole idea of shooting larger formats a waste if your not going to enlarge? What about the costs of mats, paper, frames etc. when your dealing with larger prints? How many people even have the wall space to hang more then a dozen or so larger prints? When is the use of larger formats justified from an image quality point of view? I know 35mm is the most versatile format. Should I even consider other formats if I never go for prints larger then 13" x 19"?
