Rodinol min. vol. at high dilutions : LUSENET : B&W Photo - Film & Processing : One Thread

I want to dilute Rodinol at 1:150 for tech pan. Can I use just 3 ml. concentrate to process a roll of 35 mm?

Thanks in advance, Michael.

This is probably a terrible answer, but I always take the safe approach with minimum stock. I use 40oz water+developer per roll of 35mm if I use anything 1:100 or over with Rodinal (double my normal 20oz).

I regularly use Rodinal 1:200 (2.5ml Rodinal / 0.5l water) for TechPan. I measure out 2.5ml of Rodinal using a medical syringe, and dump that in 1/2 litre water. Make sure the Rodinal falls straight into the water and doesn't stick to the sides of the graduate, and keep stirring.

Michael...I have developed hundreds of rolls of APX 100 and 400 along with many rolls of TriX all in Rodinal at 1+100 in plastic tanks that require 300mls (really 280) of solution. I use 3mls of Rodinal plus 300 mls of 68 degree water for 20 minutes. This information came from a Agfa handout...hope this helps...jim
