Combi Plan tank - my developing times

[chy]

Since there is quite a bit of interest in the Combi Plan tank, I looked for my original instruction sheet and the notes I wrote on it. Here are the developing times of some film and developer combinations I used and hopefully it can help someone as a starting point.

Please don't take it as gospel, it worked for me for a long time and it might or might not work for you as my films, developers and processing times are from the previous century Maybe the goodies in the water are different nowadays! I did fine tune developing times depending on subjects and exposures, so your times might very well be different from mine.


=====================

Fill time - +/- 30 secs.
Drain time - +/- 30 secs.
1200ml of solution

I've always used a water pre-wet - 1 min. and an inversion or two, not critical. Use the same temperature as the intended developer.

General agitation pattern - Continuous inversions first 30 secs., then 2 inversions every 15 secs.

======================
KODAK PLUS-X

D-76, 1:1 dilution - 8 mins. @ 70 deg.F
HC-110, 1:31 dilution - 6.5 mins. @ 68 deg.F
Sprint Standard, 1:9 dilution - 10 mins. @ 68 deg.F

======================
KODAK T-MAX100

HC-110, 1:31 dilution - 7.5 mins.
(agitation is continuous first 30 sec., then 6 inversions every 15 secs.


Hope this helps, good luck!

Hi, have you considered adding these to the Massive Dev Chart ??

If I don't know the processing for something, I usually look there

I don't think Plus-X has been available as sheet film for many years. TMX formulation changed circa 1999, I think.
