Re: measuring spoon method

Occasionally, I will mix my own film developers, not that I can't afford to by ready-mixed, but because I enjoy doing it, and it adds to the personal involvement in the production of the end product, the photograph. I have a formula for Adox borax MQ developer. I would like to mix up this concoctio...

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...

Exposure and development of B&W Films.

There have been a lot of questions posted here lately about uprating film speeds and push processing, particularly by beginners. Personally, I like to do the opposite and err towards the generous side of exposure and controlling contrast by adjusting the developing times to avoid over development. T...

Re: Rodinal: Using Andersen's formula.

Thanks for posting. I've been developing & printing film since 1971 and have never used Rodinal - I have been in the HC-110B camp since around 1976 (just finished 12 rolls of HP5+ & 2 rolls of Delta 3200 tonight) and rarely leave. When I do step out it's D-76. I just might give mixing my own Rodina...

Re: Help needed with Kienzle A69S

Hi, I am a user in public darkroom in Aarhus, Denmark. We have just been given a very generous gift, a Kienzle a69s. It is by far the most advanced enlarger we have, but it came without a manual and I wondered if somebody could help me understand what the d-max control does (none of our other enlar...

Re: Rodinal: Using Andersen's formula.

Yes that would be one option. And completely worry free. But can I ask you, if you looked up the book with its information? It would be interesting to know if you had done so. Just asking? Than You Kenny E Hi Kenny, Is this the book you referred to? https://archive.org/details/organicphotograp00wei...

Re: Rodinal: Using Andersen's formula.

To Kenny E.

How authentic are these formulas? https://www.digitaltruth.com/articles/h ... odinal.php

I always thought that Agfa used P-Aminophenol base rather than the hydrochloride. A caustic alkali is listed in Rodinal rather than carbonate.

Also, I am not aware of Glycin used in Microphen.

Re: Is my Microphen formula correct?

The formula I have seen which seems most authentic was posted by pentaxpete. He said he got it from an Ilford employee just as they closed their plant in Brentwood IIR correctly. Hopefully he will reply here soon. Sodium Tripolyphosphate 3.4g Sodium sulphite 100g Sodium metabisulphite 0.65g Hydroqu...

Re: Rodinal: Using Andersen's formula.

I think I would rather just buy it as sold by Adox.

Re: 120, D-76 (1:1), Tri-X 400 Underexposed

As already mentioned, it is almost certainly an exposure issue. Try exposing at the meter setting and then take another photo at a whole stop more generous. You will find that the tonality is aesthetically much nicer if you err towards slight overexposure with most B&W films. By sticking with this c...

I always use it diluted 1+4 for films and papers as recommended by Ilford with no problems.
