A 4x5 Nikkor tanks hold 12 sheets, uses 36 oz of solution.

Fill tank with developer and drop in the liquid in the dark like any Nikkor tank is best used. Grab the reel, pull out, rotate, reimmerse. 4 immersions in 30 sec is the initial agitation.

For a single sheet, a 5x7 tray works fine. I do not interleave. I have kept up to 4 trays going at once each with a single sheet.

Jobo expert Drum is the best for ease of learning.

Hangars with a hangar rack ties with the Nikkor for second place.
