Re: Latent image fading

I was speaking with Timothy Stearman yesterday. Timothy's company, Stearman Press, markets daylight developing trays and tanks for large format. He mentioned that many of his customers are young photographers who are struggling to teach themselves, for lack of darkroom courses in school I assume, ho...

Re: Minimum Developer per 80 sq. in. of film - clarification

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.

Re: Latent image fading

Greetings, Tim. I have never heard of latent image fading. That doesn't mean it doesn't exist. What does exist is increased base fog that severely reduces sharpening. This is caused primarily by background radiation that is ever present, even in cold storage. In essence, background radiation from th...

Re: Wynn Bullock's Carbonate solution

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:

Thank you for this post. It's good information to have. We'll be looking forward to hearing your results using "more modern divided developer formulas."

Question: Has anyone else had similar results with divided developers and modern emulsion film?

Re: Developing film for scanning

I suggest underexposing by one stop to preserve maximum shadow detail for scanning, then compensating for the highlights with underdevelopment. The traditional two stops recommended for wet printing may work just as well. Try exposing a scene with one stop and two stop underexposure and seeing which...

Re: Developing film for scanning

Welcome to the club, Steve. The advice you have been given to create flat negatives with maximum information in both the shadows and highlights, and then pump contrast into them during scanning is good. Overexposure will provide good detail in the shadows, underdevelopment will help control the high...

Large format camera at Historic Event

It takes a great deal of courage to show up to photograph a historic event with a large format film camera; especially when you're surrounded by digital photographers. David Burnett displays that courage. https://www.dpreview.com/articles/2937027624/photographer-david-burnett-at-today-s-impeachment-...

Re: washing time with alkaline fixing

It's really quite simple. What you want is to wash the chemistry out of the emulsion. The uncoated back of the paper (RC or Fiber) will stick to whatever side it is against. So, if the emulsion is facing the back, the emulsion will stick to the back and washing cannot occur. However, if the emulsion...
