Noepan 400 and HC110 1+50 time??

[stradibarrius]

Has anyone used HC110 1+50 to process neopan 400 @400, 20C?

MDC has 7 min for "H" I thought I would try 8 min....Opinions

I love the results with D-76 1:1 so much that I can't bring myself to try anything else with it, now that it is out of production (120 ONLY)

HC110 development times tend to change proportionally to dilution, eg twice as dilute solution, twice as much needed development time. Dil B is 1+31. The ratio between Dil B and 1+50 is 51/32 ~= 1,6. So, get the development time from here (5') and multiply by 1,6. That will give you 8'. That should be a good starting point, adjust according to taste...

says 4 minutes for the 1+15 dilution at 20 C to get a gamma of 0,62 and 6 minutes for the same with 1+31. About 8 minutes for 1+50 could be a good starting point.

Well I'm am going to give 8' @ 20c a try and see how it works.
8' seems to be the magic number for so many films with HC110 1+50.

I developed these Fuji Neopan 400 photos in HC-110, dilution H at EI 400 for 10 min. See also here: http://monochrome.me.uk/blog/index.php?x=development

Go to www.covingtoninnovations/hc110.com for the best source of information about HC-110. To answer your question develop for 50% longer than dilution B. This is what covington gives for dilution E, 1:47 which is close enough.
