As readers of The Cookbook know, the goal is to share darkroom tools, tricks, and techniques so they are not lost or need to be rediscovered by future generations. For this edition, I would like to invite members of the darkr...

Re: Variable green toner

Can't recall why I dropped it. However, if you have used it, what were your results? Also, I would toss the second ed. It has a lot of serious errors that were mostly addressed in the third ed. and pretty much fixed in the 4th. I am currently working on the 5th ed., which will substantially differ f...

Re: Diafine in SP-8x10 tank?

I apologize for the lateness of this response. Your solution is probably correct. No development takes place in the A Solution. So, try using it (if you already haven't done so) as a presoak just as you would plain water. You should be able to presoak it for the usual time. Please let me know how th...

Re: No Scratch

One of the most effective methods for making scratches disappear is nose grease. Rub both sides of the negative across the tip of your nose, this will eliminate all but the worst scratches. I never had much luck with Edwals Anti-scratch. Nose grease works better.

Re: Aristo cold light head

The purpose of the D-57 was to get the grades to be as linear as possible. It, too, was not perfect but we got very close, tweaking with the appropriate filter, and Roscoe was the filter mfr. of choice, got it even closer with specific papers.

Re: Aristo cold light head

I did the testing and evaluation for the D-57 head for Aristo. It was intended for use with VC papers. The D-55 had an equal balance of blue/green phosphors. This combination worked well with graded papers but required the addition of a green filter to work with VC. The D-57 has 30% blue and 70% gre...

I just saw this post. Tim is correct, 1:4 means 1 part developer to 4 parts water to make the desired amount of stock developer, as in option B. If you see it written otherwise in the FDCB let me know.

Re: Effect of less sodium sulfite?

Were you able to print any of them? If so, how did they look? My guess is that they had slightly more graininess. Also, because these were made under controlled lighting the contrast was lower on the negative and the lack of 25 grams of ss was not an issue.

There is a brief discussion of Perfection XR-1 in the new edition of the Film Developing Cookbook. The formula is proprietary so the exact formulation is not known, but we do give two patent formulas that are very close. It's in Chapter 10, page 128. We forgot to put it in the Index. :roll:
