I use all my developers as "one shot" so I end up mixing small quantities. Hard to do with TMax RS unless you use a lot of it. I shoot 2 or three rolls a week plus a few 4x5's. TMax RS has a rather short shelf life once mixed. Non-RS Tmax can be easily mixed from the bottle but TMax-RS has 2 parts, one of which is too small to measure for small batches. I guess my real question here is "Is the sheet film uneven development problem with TMax non-RS developer due to agitation and will processing the sheets in BTZS tubes cure that problem"?(posted 8513 days ago)
