Update 3 - DIY PVC Tube Development Timeline for Two Films

April 16, 2017  •  Leave a Comment

My DIY film development tubesMy DIY film development tubes In my quest for being more efficient with my semi-stand development process for individual films, I needed a method to develop more than one film at a time. 

The approach that I outline below works best when the total time for presoak and initial agitation are greater than the stand development cycles for the two films.  I use 3 timers.  Timer 1 is dedicated to film # 1’s current process, Timer # 2 is dedicated to film # 2’s current process, and the third timer is used for the agitation cycles.  I also recommend numbering the tubes and the timers, to keep track of them and not rely on placement (left or right).  

I use a small whiteboard to write down the development plan and erase each step for each film as I complete it.  You could accomplish the same thing with a piece of paper and mark through each step as it is completed.

Two Film Development Timeline for Individual Tubes of Film

Step 1 - Film # 1 - presoak for 5 min 
Step 2 - Film # 1 - initial agitation (ranges from 2.5 to 5 min depending on development needed) 
Step 3 - Film # 1 - stand # 1 for 15 min. (this can vary, I used 15 min as an example) 

Step 4 - Film # 2 - presoak for 5 min 
Step 5 - Film # 2 - initial agitation (ranges from 2.5 to 5 min depending on development needed)
Step 6 - Film # 2 - stand # 1 for 15 min (this time ranges between 5 and 20 minutes) 

Step 7 - Film # 1 - agitation cycle # 1
Step 8 - Film # 1 - stand # 2 for 15 min.

Step 9 - Film # 2 - agitation cycle
Step 10 - Film # 2 - stand # 2 for 15 min.

Step 11 - Film # 1 - agitation cycle # 2
Step 12 - Film # 1 - stand # 3 for 15 min.

Proceed to step # 15 for film # 1

Step 13 - Film # 2 - agitation cycle # 2
Step 14 - Film # 2 - stand # 3 for 15 min.

Proceed to step # 15 for film # 2

Step 15 - stop/fix/wash film # 1
Stop bath for 30 seconds with film # 1
TF-4 rapid fix for 5 min for film # 1
Wash film # 1 
Photoflo and hang to dry

Note: I remove my films from the tube and go to trays for stop, fix, and washing.  I am currently testing a new method that will simplify this for my mobile darkroom.  

Step 16 - stop/fix/wash film # 2
Stop bath for 30 seconds with film # 2
TF-4 rapid fix for 5 min for film # 2
Wash film # 2
Photoflo and hang to dry
