Rather than trying to process in a changing box why not use a roller base and print processing drum. Several companies make (or made) them and you can get them new or used. If you want you can make your own processing tubes from PVC plumbing pipes. See Phil Davis' "Beyond the Zone System" book for instructions on how to make the tubes. The View Camera Store (formerly Darkroom Innovations) sells ready to use tubes (molded plastic rather than glued up from PVC), and has instructions for their use available online. They assume you're going to use it for film processing. They should be OK for paper too. > I was wondering if I could place a window into each of these boxes > so that my students can see what they were doing.

I think you'd wind up fogging the paper. -- Brian Reynolds | "But in the new approach, as you know, reyno...@panix.com | the important thing is to understand http://www.panix.com/~reynolds/ | what you're doing rather than to get NAR# 54438 | the right answer." -- Tom Lehrer
