andy_sprauer Posted December 3, 2004 Share Posted December 3, 2004 Which HC-110 dilution B,C,D,E would be best to develop Tri X 120 size film exposed at 400ASA. I used to use D76 1:1 & was happy with the results. I need to know the dilution ratio & time since I'm changing to HC-110. These variables are throwing me a curve ball. I'm going to have the developer temp at 68 degrees. A condensor enlarger will be used. I'm familiar with the Convington site but need your tried & tested input. Thanks for all you help.

scott_eaton Posted December 3, 2004 Share Posted December 3, 2004 IMHO - #B (1:31) has worked the best for me with Tri-X. Not trying to steer you in a different direction, but HP5 seems to respond better to HC110 than Tri-X. Tri-X works in HC-110, but it's a utilitarian combination if you ask me. However, HP5 'glows' in HC-110. Please give it a try when you have the chance. Link to comment Share on other sites More sharing options...
StuartMoxham Posted December 3, 2004 Share Posted December 3, 2004 I use dilB with TriX 35mm and HP5 120 format and both combos are great. I I don't really shoot many other films these days I find that these 2 combos really cover my needs. Link to comment Share on other sites More sharing options...
andy_sprauer Posted December 3, 2004 Author Share Posted December 3, 2004 My specific question is - how much development time?? Link to comment Share on other sites More sharing options...
remi_lemarchand Posted December 3, 2004 Share Posted December 3, 2004 I use dilution H (1:63) for 8.5 minutes at 68I have used dilution B (1:31) for 5 minutes at 68 but I find it too contrasty when exposed at 200. Link to comment Share on other sites More sharing options...
ann_clancy3 Posted December 3, 2004 Share Posted December 3, 2004 we have several students using "B" at 6 minutes, 68 degrees., they printing with condensor head. Link to comment Share on other sites More sharing options...
doug_bennett Posted December 3, 2004 Share Posted December 3, 2004 I'm not a Tri-X user, but with HP-5 rated at ISO 200, I use dil. H for 7 minutes. Link to comment Share on other sites More sharing options...
lex_jenkins Posted December 3, 2004 Share Posted December 3, 2004 There really isn't much to add to Covington's site. The information there is reliable and matches my own results. Years ago, when I was a photojournalist, I used Dilution B because it was quick. Development times were usually around 5 minutes depending on temperature. However back then I wasn't as concerned about even development and consistency as I am now. Based on the recommendations of other photo.netters I've since switched to Dilution H, which is simply twice as dilute as Dilution B. I develop for twice the time, again depending on temperature. I've compared my current negatives with those from twentysomething years ago. They are virtually identical in every way: grain, contrast, tonal range. The longer development time gives more margin for error. Pour times are less significant a factor. This should improve the odds of getting even, consistent results. Also, the results are very comparable to Tri-X in D-76. So I have no need to keep yet another developer on hand. This suits me since I've found that D-76/ID-11 can produce variable results over the six-month period (at most) I'd typically keep a batch of stock solution before replacing it. Some formulations of D-76/ID-11 have been reported to vary in strength over a six-month period so I prefer the uniformity and longer shelf life of HC-110.

joey Posted December 4, 2004 Share Posted December 4, 2004 HC-110 dil. B, 68 degrees F, 2 inversions per minute, condenser enlarger, shot at 400. Prints beautifully! Link to comment Share on other sites More sharing options...
andy_sprauer Posted December 4, 2004 Author Share Posted December 4, 2004 Joey - nice response, but how many minutes?? Link to comment Share on other sites More sharing options...
mskovacs Posted December 4, 2004 Share Posted December 4, 2004 I find that HC110 is a pretty energetic developer so don't over-agitate the tank for best results. I give just the slightest twirl with my Patterson tank every minute. Link to comment Share on other sites More sharing options...

david_grasby Posted December 6, 2004 Share Posted December 6, 2004 I use HC110 at a 1:59 dilution, which is approximately Dilution H. My time for Tri-X (120) is a bit longer than others though...12 mins at 22C for an E.I. of 320. Link to comment Share on other sites More sharing options...
jim kerr Posted December 16, 2004 Share Posted December 16, 2004 I've had good negatives with HC-110 B at Kodak's recommended times, also I've done what Ansel Adams wrote about in "The Negative". The newer version, where he used a more dilute version than B. But then, I've been using a diffusion colorhead to print with for the past 25 years or so...Jim Link to comment Share on other sites More sharing options...
