NOTE:  For KB 100 I'm using two agitation patterns to see how density is changed:

    (x) = Continuous 15 seconds, then 3 inversions in 5 seconds every 60 seconds.  (2x) = Continuous 15 seconds, then 3 inversions in 5 seconds every 45 seconds.

 

 

Development Stats:  Two reel stainless steel tank, inversion and twist agitation.

 

1.  Pre-wet 2 min, water at 20c.

2.  Develop Beutler Formula 1:1:10.

3.  Stop with water 20c,  four dumps.

4.  Fix 5 min,  medium agitation first 30 sec then for 10 sec every subsequent 30 seconds.

5.  Wash 15 min 20c

6.  Photo flow 30 sec

7.  Hang dry
