Re: Is my Microphen formula correct?

I got a copy of the SDS sheet from Digitaltruth. It states that Hydroquinone and Boric Aid are chemicals of the developer of Microphen. This is very strange to me,because the US Military would not use Microphen if its make up was that similar or close to D-76 or D-76d. Because they have tons of D-7...

Re: Is my Microphen formula correct?

I am updating my last post. Here is the defined Ilford formula for Microphen, base on the research so far. Phenidone 0.2-4 grams Sodium Sulfite 90 grams Glycin 5 grams Sodium Carbonate 2.0 grams Borax 2.0 grams Water to make 1 liter I feel two to three week is needed to go through the files at the ...

Re: FX-39/Acros addendum questions

Hello A note attached to one of the FX-39/Acros times takes me to an addendum supplied by Michael Scarpitti with his revised time recommendations. I am new to this and need a few clarifications: 1. No temperatures are listed. May I presume that the temperature for these is 20 degrees C or 68 degree...

Re: FX39

ornello: Our film developing schemes are almost identical. The only part I am ambivalent about is the prewash. Sometimes I do, sometimes I don't. As I have said before, I shoot mostly 120 as I prefer the bigger viewfinder image. What is your preferred film with this developer? I have been using Ult...

Many thanks! I develop with the intention of scanning the negatives. Should I reduce the development time?
I would not recommend scanning B&W negatives. It doesn't work well.

Thanks for your detailed helpful reply. Have you tested Ilford FP4+?
Not yet, but I would suggest 1+17 for 7 to 7.5 minutes to start.

Re: FX39

Omello I’m about to start using FX-39. Thanks so much for working out these times. What agitation method did you use? Do the same times apply for 35mm and 120? Thanks! Steve I use 35mm only. I use Paterson tanks. Always fill the tank almost to the top, even if you are developing fewer rolls than th...

Re: Developing B&W film

ornello: my eyes glazed over before I finished the article, but aren't these procedures geared more for the lab(commercial) people? I'm sorry, maybe I zonked out before I got to the part about condenser/diffusion enlargers. also, I have not seen test strips for amateur bw use before. jim Well, I do...

Developing B&W film

A useful item:

http://imaging.kodakalaris.com/sites/ua ... y/z133.pdf

Most important:

"0.58 is the contrast-index aim for printing negatives with a diffusion enlarger; use 0.43 if you will print negatives with a condenser enlarger."

Re: FX39

Ornello Many folks are hung up about grain in the print. My personal favorite sizes are 5x7 and 11x14. Though I tend to shoot more 120 than 35mm, what can I expect from 400-speed traditional film in either format? TIA Jim M. With good technique, even with very fast films, grain is not obtrusive. Mo...

Re: FX39

Unfortunately, Fuji 100 Acros will be discontinued this year. So I have heard. I hardly ever use it, but thought I'd try it since I got a nice new(ish) 50mm Summilux-R, 1998 version. Most of my photography is done with fast films. FP4 Plus, Delta 100, and T-Max 100 are all excellent, but again, I d...

Re: FX39

OK, folks, the testing is progressing. These times are for grade 3 filtration on Ilford MG IV paper, using a condenser enlarger. Dilution 1 + 17 (NOT 1+9!!!!!!!) The dilution given by Crawley is way too low! Suggested times at 68F/20C: Kodak T-Max 400.....9 minutes Ilford HP5 Plus........8.5 minutes...
