keith_tapscott Posted September 30, 2007 Share Posted September 30, 2007 Does anyone use or able to suggest a guide time for Ilford FP4 Plus to be developed in Kodak DK-50 diluted 1:1? http://www.kodak.com/global/en/professional/products/chemistry/bwFilmProcessing/dk50.jhtml?id=0.1.16.14.30.14.7.26&lc=en Link to comment Share on other sites More sharing options...

larrydressler Posted September 30, 2007 Share Posted September 30, 2007 I would try 1-3 8 minutes for a starting point. We used to use that time for most medium speed films at the old 1970s lab. Larry Link to comment Share on other sites More sharing options...
keith_tapscott Posted October 1, 2007 Author Share Posted October 1, 2007 I couldn`t find any times for FP4 Plus in DK-50, but it has since been suggested to me to try the times for Kodak HC-110 (dilution B) as a guide with DK-50 diluted 1:1. Another interesting method, was to make Geoffrey Crawley`s modified version which is DK-50 as Part `A` and an 8% solution of Sodium Metaborate as Part `B` which I might make later today. The working strength solution consist of 2 Parts of `A` + 1 part of `B` + 7 parts of water. This is from the BJP Annual 1977 and provides a list of development times that look more manageable. Times are given for the pre-plus version of FP4 which I will try. Thanks for replying. Link to comment Share on other sites More sharing options...
keith_tapscott Posted October 1, 2007 Author Share Posted October 1, 2007 Well, I am surprised. I processed a 135-36 roll of FP4 Plus today and used DK-50 diluted 1:1 for 7.5 minutes at 20C (68F). I don`t usually use a pre-soak, but thought that I would try it due to the feedback about the developer being very rapid. The shadows looked thinner than I get with D-76 diluted 1:1 and the negatives looked a bit under developed. For the next roll that I expose, I will lower the ISO number by one-third E.V. step and develop for 8.5 to 9 minutes. I mixed the developer up fresh on Saturday morning and wanted to see how it compared with D-76, as I was thinking of using FP4 Plus sheet-film developed in DK-50. I will probably stick with D-76.

keith_tapscott Posted October 2, 2007 Author Share Posted October 2, 2007 I`ve decided to chuck the DK-50. Link to comment Share on other sites More sharing options...

robert_johnson15 Posted October 6, 2007 Share Posted October 6, 2007 DK-50 is still being made by Kodak. My local dealer has plenty of stock. If you are looking for old stock cheap - I'm not sure. I used to have some old stock, but I think I gave that away as being too old. This was the "paper type", two part bags stuck together.
