From the thread's context, I'm assuming by glass negs, you mean wet plate negatives (?) But, I would love to see an 11x14 dry plate neg enlarged. I have to admit, the idea hadn't even occurred to me. I'm currently working on restoring an 11x14 camera, and asap after the Holidays I'm hoping to shoot with it. Maybe I could send you a plate this coming early Spring and see what it looks like enlarged. Just a thought.
