Photo Forum / Film Photography / Darkroom / January 2004Kodak Dektol question
Is this developer for B/W paper only?.....or is it for B/W film also? The reason I ask this question is that I am going to make some contrast reducing masks using 4x5" TMAX100 film. For masks I need a soft developer and I was told that I could use Dektol in anout 1:30 (stock dilution and water) and then about 3 min. development time. Does it sound right? Max > Is this developer for B/W paper only?.....or is it for B/W film also? It will develop film. It is somewhat similar to D-19, but even faster acting. It acts very quickly and produces rather coarse grain. I've never heard of diluting it 1:30. I'd be afraid of uneven results. > > Is this developer for B/W paper only?.....or is it for B/W film also? > > It will develop film. It is somewhat similar to D-19, but even faster > acting.

What do you think should be the about right dilution for TMAX100 then?

However, I do not use TMAX for my masks, I use an ortho film, which is far cheaper. With enough developer solution, say an 8 x 10 tray's worth and constant agitation I have not had a problem with uneven development. Of course you could increase the dilution to 1:15 for instance, and adjust your times accordingly. Your goal is to get a mask that serves its purpose. This may be a very thin mask with detail almost everywhere but the highlights. The general rule is that the stronger the dilution the higher the contrast of the mask. Also, you might try varrying the development times, one for a minute or minute and a half, one for two minutes and so on and see which combination produces the best mask for the negative you are working with. Good luck. Dale  Signaturewww.dalestrousephoto.com > > Is this developer for B/W paper only?.....or is it for B/W film also? > > [quoted text clipped - 21 lines] > > Dale Thank you. There are many variables to control for a first time contrast mask maker. But I see no other way to improve the quality of my Ilfochrome prints. Max Dale, learning unsharp masking is something I need to do... Any suggestions for a tutorial?

In the documentation is described how do make the different masks (Contrast masks....unsharp masks....fog masks....shadow masks...ect). Also the book "Post Exposure" by Ctein describe how to make a contrast mask (which is no exactly the same as a unsharp mask but they are closely related).

Try Lynn Radeka's website. You can find him at: http://www.RadekaPhotography.com He provides a kit with a tutorial and he also offers workshops. That is how I learned.

I diluted 1 to 7, same as for HC110 solution B. I was developing Ilford FP4+ pushed to 400--about half way through developing I realized what I'd done, but continued 'til 9 minutes, which was short by a couple minutes, but then I conceded I didn't know what I was doing. I stopped and fixed and was pleasantly surprised to see workable images. High-contrast, but workable all the same. Signaturewww.mattclara.com Max, Using some info from Barry Sherman and Howard Bond, I have been making unsharp masks with 4x5 TMX developed in Rodinal 1+30 for about 3 mins. (You will have to test a bit to find the best time for your situation.) This is a good use for any old Rodinal you have sitting around and are a little shy to use on film that may contain that "once in a lifetime" image. ;-) Bob ------------------ >Is this developer for B/W paper only?.....or is it for B/W film also? > [quoted text clipped - 6 lines] > >Max > Is this developer for B/W paper only?.....or is it for B/W film also? > [quoted text clipped - 6 lines] > > Max Developing film in Dektol is an old newspaper photographer's trick. It typically gives a high contrast, grainy result (which was/is a "don't care" for most newspapers), but it's fast. IIRC, about three minutes developement time in undiluted Dektol. I know absolutely nothing about your intended application; my response is a historical curiosity, useful only for playing Trivial Pursuit! Ken Hart |
