I think I've found my calling in life....

I am happy that you have found your calling. After several careers and being semi-retired, I am still being constantly told that I have missed my calling. I am rather surprised that I am getting this from specialists in the legal and medical fields, who think that I have background in their areas.

pinhole ftw. I need to get a black bodycap for my Pentax cameras so I can do both 35mm pinhole and digital pinhole.

Apart from the Rollei 720 nm film, there is also a newer 820 nm Maco/Rollei film that is, or will be, available in 4x5 sheets. This is not the old Maco IR820 or IR820c. That is now available as Efke IR820. A 25 sheet box is $40. You could go the whole hog and use 8x10 Efke IR820.

Why not use a tank for developing 4x5?

Best,
Helen
