You should not presoak with modern films. Modern films contain agents to ensure the developer enters the film quickly and evenly. If you...
I think I understand what is going on. Tri-X in Diafine has a high contrast in the shadows, and a significant shoulder which starts at a low...
Lex, So reading between the lines of your reply, my measured speed using density 0.1 above fb+f could be valid. So there was no issue with...
I developed a test roll of Tri-X (400TX) in Diafine this weekend. The speed I found for it is around EI400 to 500 (using density 0.1 above...
<p>I rechecked Jobo USA webiste, and yes the 6 sheets are only a problem with the older 2509 reels (the non "n" version). See: </p> <a...
I agree with Steve. Photograhic Glycin (as opposed to non-photographic Glycine) has a short shelf life in dry form. Get it from Photgrapher's...
With the Jobo reels you can only do 4 sheets per reel. They originally said 6 sheets, but there were problems (I think it was some films flexed...
Ansel's book "The Negative" should give you details on how to fine tune your development time. As a start, I would look at the development times...
It is fairly easy to re-roll 120. There are a few things to watch. 1) Do not unroll too much at once. Keep the two spools quite close together,...
What you are seeing is normal. Agfa films in Rodinal give an incredibly dark purple. HP5+ in rodinal (from memory) has almost no colour.
I have experimented with Beutler developer in a Jobo machine. Results are good, but I have not had a chance to finalise my tests. Sorry, I have...
My understanding (which may be wrong) is that NaCl in the wash helps to draw out any chemicals, hence improves speed of wash. HCA style compounds...
This space is fairly typical for tanks designed to take both 35mm and 120 reels. I have never worried about it. Just let the reels slide around....
Tonality What we must remeber is that characteristic curves are only a crude tool for trying to undestand what a film + developer do. In...
A common problem is too much pressure on the sides of the film. You only need to curve it to get it started. Once you have done the first half a...
1. Jobo recommend 10 changes of water with 30 seconds rotation each (note this is not 30 seconds in the drum, but 30 seonds rotation). 2. I am...
A decent lab will be able to handle film in holders. They will return the holders to you. Once you have used up the first box of film, you can...
The use of the term "contrast" with developers, is different from contrast in a negative. From your perspective any decent developer will give...
Careful. Different developers behave differently with temperature change. The Ilford chart is for MQ and PQ developers. If you go outside the...
A two bath fix is only really needed if you are trying to get the maximum capacity out of your fixer. I prefer to use a single fix bath, and only...
