This is the process I am currently using to develop my B&W film: - determine appropriate developing time for developer (see film datasheets and account for push/pull). Currently, I am using TMax Developer (1 part concentrate, 4 parts water), and the following development times: - Kodak Tri-X 400 - 6 minutes - Ilford HP5 Plus 400 - 6 minutes 30 seconds - Agfapan APX 400 - 7 minutes I adjust the development time to suit the temperature of the developer solution just before development.
I use the appropriate amount of solutions based on the notes on the underside of the developing tank, depending on the number of rolls in the tank. I add 50CC extra for safety.
I start by pouring in water at approx 68F for 2 minutes. I agigate constantly for 30 seconds, and then 5 seconds every 30 seconds for the remainder. Agigation is done by turning the spindle in the tank back and forth (this causes back and forward rotation of the film spiral and up and down motion).
I pour out the water, and pour in the developer, starting the timer as I pour it in. I agigate constantly for the remainder of the first 30 seconds. Thereafter, I agigate 5 seconds every 30. For one roll, 10 seconds before completion, I start to pour the developer out. For two rolls, I begin 15 seconds before the end.
Immediately at the completion of the timer, I pour in the stop solution and agitate constantly for 30 seconds. When complete, I pour this back into the graduate. The stop is Kodak Indicator Stop Bath (starts deep yellow, turns purple when exhausted).
At this time, I pour in the Kodak Rapid Fixer (diluted as reccomended by Kodak), and agigate for 8 minutes, with constant agitation during the first 30 seconds. I open the film tank, pull out the film carefully, and examine to see if it has fixed properly. I put the film back, close the tank. If it has not fixed properly yet, I agigate for another 60 seconds, and repeat. At completion, I pour the fixer back into the graduate.
At this time, I pour water in, agigate for 30 seconds, and pour it out.
I then pour in Heico Permawash. I agigate for 2 minutes, agigating constantly for the first 30 seconds. At completion, I pour the heico back into the graduate. I haven't determined if saving the working solution after use is safe or not, although the bottle indicates there is a 90 day life in an air-out bottle and that one batch of working solution can do over 100 rolls (i can't recall the exact number).
Finally, I fill the tank, pour out the water, and then I put the hose into the center hole of the tank and let water run for 6 minutes, periodically dumping the water out and putting the hose back in.
When complete, I pour the water out, put fill it back up, put in a couple drops of Edwal LFN, recover the tank, invert it gently twice, uncover the tank, and remove the roll. I then remove the roll from the spindle, open the spiral carefully, squeegee it as i remove it from the roll, and put the clips on and hang it to dry.
Is anything amiss in my process?
