So, a couple years ago I purchased some glass plate film holders at auction, and they looked like standard 8x10 film holder size. I was thinking I could adapt one to wet plate use, with my standard 8x10 film camera. But no....they are wider and will not slide into the back of any of my 8x10 film cameras. My question is....is this the norm? Were there glass plate holders that would fit in view cameras intended primarily for film holders?
