niall_church Posted August 18, 2004 Share Posted August 18, 2004 Does anyone have rating and developing times for acros 100 and Neopan 400! Niall Link to comment Share on other sites More sharing options...
chris_waller Posted August 18, 2004 Share Posted August 18, 2004 Try the Massive Development Chart at www.digitaltruth.com. Link to comment Share on other sites More sharing options...
michael_hohner Posted August 18, 2004 Share Posted August 18, 2004 <a href="http://www.digitaltruth.com">Digital Truth</a>, and go to Fuji to download the data sheets. Link to comment Share on other sites More sharing options...
niall_church Posted August 18, 2004 Author Share Posted August 18, 2004 ....Sorry,I should have added that I'm using Rodinal! that Massive thingy doesn't have the details I require neither does Fuji! Niall Link to comment Share on other sites More sharing options...
steven_palmer1 Posted August 18, 2004 Share Posted August 18, 2004 Niall, I just encountered the same problem. I had a roll of Neopan 100 Acros which I wanted to develop in Rodinal and found a recommended time of 1+25 @ 20 C for 7 min. The negs came out fairly contrasty but the original scene was also very high contrast. It is the only recommended time I found so that's all I can suggest. Hope this helps.

beau 1664876222 Posted August 18, 2004 Share Posted August 18, 2004 expose at 64, dilute 1:50, develop at 68F for 10 minutes, agitating once per minute. That's for scanning -- develop a little more if you're printing conventionally. Link to comment Share on other sites More sharing options...
aeiffel Posted August 18, 2004 Share Posted August 18, 2004 also check the answers you get when you directly ask a <a href="http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=009AKV" target="_blank">question</a> to someone. Link to comment Share on other sites More sharing options...
niall_church Posted August 19, 2004 Author Share Posted August 19, 2004 ....Yes freddy I did get YOUR answer before,I haven't forgotten,I just want some more opinion on the matter! Also I am Addressing this to rodinol users, and hope to get answers about 1:25 dilutions as well! That way I can make an informed discision on the matter!

Woolwinder Posted August 19, 2004 Share Posted August 19, 2004 If it is of any help, I use HC110 Dil H. at 22degC 9m 30sec. 120 film. Good negatives. Link to comment Share on other sites More sharing options...

niall_church Posted August 19, 2004 Author Share Posted August 19, 2004 Sorry Michael I don't actually use a computer it's just an email machine,so, I can't read PDF files! Niall Link to comment Share on other sites More sharing options...
lex_jenkins Posted August 19, 2004 Share Posted August 19, 2004 I see no data on those PDFs regarding Rodinal. The method I recommend for establishing data when none is availabe is to use the typically recommended development times (at a given dilution) for a given developer when used on other films as a baseline. For example, if the typical time for developing most or many films in D76 at a 1:1 dilution is 10 minutes, that's the baseline time I'd use for a film for which no data is available for developing that film in D76. Expose the film according to its nominal ISO speed - you can make adjustments to this later according to your preferences. Develop a few frames - a test strip - at the baseline time your research indicates would seem to be suitable as a starting point. Based on the results, adjust your development times until you get the desired results, using a few frames of your test roll or rolls for each test. It's time consuming, tedious and the only way to determine the best development time for a given exposure index based on your metering habits and other factors.
