Hi All! I'm a first-time poster on APUG and am very excited to be a part of the community. Hopefully this isn't a redundant thread, and if so, please direct me to the appropriate thread and I'll take this one down. With the advancement of digital scanning and printing technology, museums and galleries are turning their eyes to huge, beautiful prints. A professor of mine recently started exhibiting in Germany and they requested that his prints be 40" x 50". That is soooo big! My professor (along with many other working artists) turn to professional printing services to accomplish prints this big. They drum scan the negative and use a (correct me if I'm wrong) hybrid printer emitting RGB light onto photographic paper and develop within the printer. This costs an incredible amount of money. My professor invested about 15k into these prints, without getting any gear. That money went directly to the printer and the prints went directly to the gallery in Germany. Now, I understand this is an investment and what better investment can their be (i.e. investing in one's self)? However, I don't have the funds to do that at this time. How do those of us still working with traditional materials in traditional darkroom spaces compete with the size and quality being produced by advancing technology? How can I process prints 30"x40" or larger? I'm interested in hearing the variety of techniques out there. I've heard of people developing in wallpaper trays, but there is not much literature out there and very little detail on forums. I've also thought of creating a series of dip-tanks made of Plexiglas (similar to a big, thin fish tank with multiple chambers) but I am not an engineer and worry that the water pressure would force the Plexiglas apart. Please post your techniques with detailed explanations or links to outside literature. Thank you!
