Yes
so i shot some old np55 film i got off ebay awhile back, finding it hard to find dev info :/

i shot it at iso 25 which maybe abit to slow :x and i use id11, any help? anyone else shot what they bought yet?
 
found some info for hc-110 b for 6 mins np55
other chart says delta 100 with hc-110 6 mins
so should in theory be able to mirror the dev time of delta 100 with id11?

should i shorten the dev time?
 
Have you got another roll you could shoot at a couple of speeds and do some tests before you potentially ruin the current roll? Failing that @Asha I think has done some stand developing with id11 he might know.
 
ive got some off cuts from end of the roll and beginning which tore, might be able to clip test those?
 
That might work, I've never done one but I expect it'll be well documented .
 
I've just done a little digging.

This site has a post from someone who has the datasheet for the film and states that the development time is 6 minutes in ORWO developer 17. What's that, you ask? Well, an ORWO pdf file for their special films lists it for use with them, and says that the time is the same as Kodak D96 (sic - not D76). This site gives the difference between D76 and D96. I haven't fully digested the practical effect of the difference, but given that D96 has extra restrainer and less developing agents, I'd guess that it's designed to slow things down somewhat, and curb contrast.

If the film is old, I'd expect a loss of contrast, which would be boosted again using ID11 (possibly depending on the dilution).

My best guess - 6 minutes :D.
 
im thinking of doing 10mins with id 1+1, think thats slightly shorter than equivilent to maybe make up for to much up over exposure, maybe :x
 
Never used id11 tbh but going on other developers i wud be quite confident that à semi stand 1:100 solution would work ok although it may not give as good results as if you dev for à "standard" time....my advice: semi stand 1:100 ( is what i would do) or about 6 mins as recommended by Stephen dépendent on the solution strength.
 
well ended up doing 6mins or so i guess, negs came out abit dark, so next film i do i can shoot at 50iso or/and shorten dev time, and agitate less, cos after i pored in dev i forgot if i had put enough in :x, and first time using just dev with no watering down
 
The question really is - is the film overdeveloped or overexposed? Overdevelopment results in increased contrast.

The next question is - are you printing conventionally in a darkroom, or scanning, because if the latter you have a greater degree of freedom than you have in the darkroom. Scanning can cope with contrast ranges that are beyond the range that printing papers can handle.
 
ill be using my a77ii to photo the film, so I could hdr it if needed, I shot the film in a yashica 127 so the 35mm film is exposed full width and taller
