willscarlett Posted October 15, 2006 Share Posted October 15, 2006 I got a few rolls of Tech Pan from a teacher of mine and while I haven't shot any yet, I was looking up the best way to develop it - he said the developer Technidol is specifically for Tech Pan, but some other developers also yield good results. I was wondering if anyone has examples of images they've shot on Tech Pan and developed in various soups, such as Technidol, Rodinal, D-76, Dektol, C-41?

stephen hazelton Posted October 15, 2006 Share Posted October 15, 2006 It depends on what you want to do with it. For normal picture use, you want the Technidol. I've tried a roll or two in D76, and it gives very high contrast- may look neat for certain images, but not for a normal picture (the "brick man" shot in my portfolio is a combination of 2 images, and the face was Tech Pan in D76).

bljkasfdljkasfdljskfa Posted October 16, 2006 Share Posted October 16, 2006 Microphen at 1:5, for 14 minutes at 75 degrees can give excellent results. Link to comment Share on other sites More sharing options...
terry_m1 Posted October 16, 2006 Share Posted October 16, 2006 Go to Photographers' Formulary on the Web and see the details of their special Tech Pan developer. It allows you to change the ISO of 25 up to approximately 65. I've tried it and it is a wonderful combination! Link to comment Share on other sites More sharing options...
wickedmartini Posted October 16, 2006 Share Posted October 16, 2006 Many of your usual developers can yield rather high contrast. Technidol is a soft working developer that will yield a nice continuous tone negative. My other favorite developer to use with Tech Pan is Xtol. Check the data sheet for processing times and contrast index. Link to comment Share on other sites More sharing options...
bljkasfdljkasfdljskfa Posted October 16, 2006 Share Posted October 16, 2006 Technidol works, but not the best developer for this film. Microphen is better, 510-pyro is better, the specialized formulary developers are better. Link to comment Share on other sites More sharing options...
carey_russ Posted October 16, 2006 Share Posted October 16, 2006 I've used Rodinal at 1:100 with good results. Link to comment Share on other sites More sharing options...
willscarlett Posted October 16, 2006 Author Share Posted October 16, 2006 Thank you all for the replies so far, they've been helpful. I was wondering if anyone has any image scans of Tech Pan photos processed in different kinds of developers. I'm more interested in seeing some of the alternative, more high contrast developments.

kirk_teetzel Posted October 17, 2006 Share Posted October 17, 2006 I've used Perceptol with very nice results. Link to comment Share on other sites More sharing options...
robert_mccann Posted October 17, 2006 Share Posted October 17, 2006 D-19 or Dektol for super high contrast- with NO greys- I shoot at iso 200- 3 min in dektol and 6 in D-19. This is with the 120 version, but I believe they are the same. Link to comment Share on other sites More sharing options...
jay_de_fehr Posted October 17, 2006 Share Posted October 17, 2006 I've used many different developers for TP, including: Technidol, TD-3, 510-Pyro, and various one-off developers. For me, 510-Pyro is the easiest to use, and produces the best results most consistently. TP is a very thin emulsion film, and does not respond well to high sulfite developers like D-76, or even Xtol, sacrificing sharpness and getting too mushy for my taste. 510-Pyro is sulfite-free, and the tanning action enhances sharpness and definition, without sacrificing gradation. High contrast is very easy to acheive with TP and just about any developer, it's low contrast that is the challenge. I use 510-Pyro 1:500/20min/70F/semi-stand. Good luck.

willscarlett Posted October 17, 2006 Author Share Posted October 17, 2006 So the Pyro developer also gives images that sepia-like tone? Link to comment Share on other sites More sharing options...
jay_de_fehr Posted October 17, 2006 Share Posted October 17, 2006 No, the tone is in the print. Pyro stained negs are greenish-brown. Jay Link to comment Share on other sites More sharing options...
ole_hjalmar_kristensen Posted October 17, 2006 Share Posted October 17, 2006 I have used Rodinal with pretty good results. Mostly 1:100 to tame contrast, but here is a raw scan, exposed at 50 ISO, developed 4 minutes in Rodinal 1:50.<div></div> Link to comment Share on other sites More sharing options...
big toys are better Posted October 17, 2006 Share Posted October 17, 2006 Thin, fine grained emulsions won't do well with a solvent developer unless highly diluted. The Rodinal proponents have it right, although you'll find that a higher dilution and less agitaiton will do a better job at controlling the inherently high contrast of Tech Pan and similar films. The massive developement chart has dilutions as high as 1:300 listed, some with a bit of sodium sulfite added which will improve apparent film speed, but I think that 1:200 without additives and with good agitation every 3-4 minutes will work a bit better. Rodinal doesn't suffer from bromide drag, and with no sulfite to dissolve the silver grains, replating also isn't an issue. Link to comment Share on other sites More sharing options...
willscarlett Posted October 17, 2006 Author Share Posted October 17, 2006 Does the same info stand true for other thin emulsion films, such as the Rollei Pan 25? I've only shot two rolls - and mind you, zero rolls of Tech Pan - but to me, the Rollei 25 emulsion looks very thin. Would that film also be better developed in a highly diluted developer? So far I've been doing it in straight D-76. What about the Efke 25? Other inputs on Tech Pan are still welcome. Link to comment Share on other sites More sharing options...
bljkasfdljkasfdljskfa Posted October 18, 2006 Share Posted October 18, 2006 It's actually easy to underdevelop it in Microphen 1:5. I just printed this at maximum magenta. Sorry, not very good artistically. Microphen 1:5 is also a staining developer. Brown stain. Link to comment Share on other sites More sharing options...

bljkasfdljkasfdljskfa Posted October 18, 2006 Share Posted October 18, 2006 I also want to mention my surprise today when I enlarged a 35mm tech pan at maximum enlarger head height. I still couldn't focus using a grain focuser (maybe because the lens was too soft at this magnification). It's hard to believe just how tiny the grain is.

bljkasfdljkasfdljskfa Posted October 18, 2006 Share Posted October 18, 2006 Here's an example of tech pan without red filter. Underexposed, empty shadows, not easy to print.<div></div> Link to comment Share on other sites More sharing options...
willscarlett Posted October 18, 2006 Author Share Posted October 18, 2006 That Bin Laden shot looks good to me...maybe my eye isn't just as finely tuned yet. Is it alright to use a Y2 filter with Tech Pan? I've noticed that the grain on Rollei Pan 25 is really hard to focus on, even using that grain microscope thing.

bljkasfdljkasfdljskfa Posted October 18, 2006 Share Posted October 18, 2006 "maybe my eye isn't just as finely tuned yet." Not necessarily. Different tastes for different people. Use any filter you like with these films. Tech pan has extended red sensitivity - sort of like Ilford SFX. Link to comment Share on other sites More sharing options...
profhlynnjones Posted October 18, 2006 Share Posted October 18, 2006 Hello John-Paul, et al My best results for Tech Pan have always been with(and I still have a few rolls in the freezer) Rodinal 1:100, 6.5 min,68F, 6 min 70F, 5.5 min 72F, 5min 75F, all at ASA/ISO 50 under normal lighting conditions. Under all conditions at 68F try these: SHADOWLESS lighting, ASA 125, 12 min. FLAT lighting, ASA 100, 8.5min. NORMAL lighting, ASA 50, 6.5min. CONTRASTY lighting, ASA 32, 5.5 min. VERY CONTRASTY dlighting, ASA 24, 4.5 min. If I'm not mistaken, this film was created as Kodak Shell Burst Pan for the government and researchers. They set up a low contrast developer and sold it to photographers as Tech Pan in order to create enough production to warrant making it.

willscarlett Posted October 18, 2006 Author Share Posted October 18, 2006 Just curios as to what kind of look you'd get if you rated Tech Pan at 200 and developed normal in D-76 Link to comment Share on other sites More sharing options...
robert_mccann Posted October 20, 2006 Share Posted October 20, 2006 Probably pretty high contrast- I've used HC-110 B on the 120 shot at 200 and got very contrasty- like a grade 6 or 7 print from a regular negative. This image is tech Pan 120 @ 200 in D-19. Link to comment Share on other sites More sharing options...
