I got into ULF when someone on this forum said that I could not build a ULF camera by hand. Oh yeah, I said! So I built my 8x20 and 11x14 cameras from some fine Walnut with matching tripods. Even made the Walnut barrel for my 14" commercial Ektar! Some simple hand tools and a Dremel in my one bedroom apartment. Boy are they fun to use and the images are not bad either.
