I have lots of experience processing B&W film so this question relates to the equipment needed to process 4x5 sheet film. I have tanks and reels to process roll film and know how to use them.
If you had no, LF tank, LF tubes etc to process sheet film and could start fresh, what type of processing tank, tray or tube would you invest in.
I have seen some videos for the BTZS tubes that seem easy to make and use. Of course I can use my trays that I develop my prints in.
