yog_sothoth Posted August 31, 2008 Share Posted August 31, 2008 So, the ATP 1.1 in the Rollei low contrast developer seems to be a winner in my eyes. These were shot at EI 12 and developed for 6 minutes in the RLC developer. No stop was used.<div></div> Link to comment Share on other sites More sharing options...

willscarlett Posted August 31, 2008 Share Posted August 31, 2008 What kind of water did you use? The instructions for this film say to use demi water. Mine had distilled water used on it - is that the same as demi water? In any event, I got a funky chemical reaction that left pepper spots on my negs. You can see the thread I posted a few days ago to see results, using the ATP DC developer and rated at 25. Link to comment Share on other sites More sharing options...
willscarlett Posted August 31, 2008 Share Posted August 31, 2008 Also, remember that your lighting conditions for the last roll in Rodinal vs this roll in RLC were totally different. That will play into your results as well. What you really need to do is shoot the same things, under different conditions, with a few different rolls and develop them all in different developers.

Fotohuis RoVo Posted September 1, 2008 Share Posted September 1, 2008 Well, great results which should be the case if you're following the right specifications and conditions for this new Technical Pan film.No, distilled water and demi-water is not the same. Apart from the tremendous differences under the different water you can make or buy. Link to comment Share on other sites More sharing options...
lex_jenkins Posted September 1, 2008 Share Posted September 1, 2008 "Demi water" is demineralized water. We don't often hear the term in the U.S. or see it readily available. It can be prepared various ways (membrane filtration, dialysis), not necessarily through distillation, but the end effect is the same as distilled water for darkroom use.

yog_sothoth Posted September 1, 2008 Author Share Posted September 1, 2008 I always use distilled water for mixing chemicals and final rinse. This is for consistency and because the tap water in my downstairs bathroom/darkroom comes out brown at first it it has been too long. Chemistry labs often have a setup to turn tap water into deionized water for laboratory use. While it would be great to get the lab-quality DI water, I will take my chances with the grocery store distilled water. I am guessing that stuff varies in quality from jug to jug, but it is better than my basement tap water. I am very pleased with the sharpness and tonality of the ATP 1.1 in the RLC developer. At EI 12 the ATP 1.1 is slower than a lot of extremely fine gain films that are easier to use, however. Link to comment Share on other sites More sharing options...
acmelabs Posted December 29, 2008 Share Posted December 29, 2008 <p>In our lab we have an on demand RO/DI system to dispense DI water, but I need to purchase my photo water as "steam distilled" (at least in Canada) :-) I have found the EI of ATP 1.1 to be:<br> 12 using Rollei RLC at 6 minutes with a Pentax 67II/165mm/K2<br> 16 using Formulary TD-3 (modified) at 21 minutes with a Pentax 67II/165mm/K2<br> I guess I won't be shooting moving trains with this, but the detail and "scanability" of this film is amazing. <br> materialsguy</p> <p> </p><div></div> Link to comment Share on other sites More sharing options...
