Re: Rodinal: Using Andersen's formula.

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

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 Hydroqui...

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...

Re: Ilford Hypam

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

Re: Spur PDX & Rollei RPX-D.

It's time to give some feedback from the developers I have tried recently. Both the Rollei RHS and Adox FX39 are excellent developers if you want the convenience of a liquid concentrate.
Of the two, the FX39 seems to give finer grain and smoother tones while maintaining good sharpness.

Re: Spur PDX & Rollei RPX-D.

Robert, have you ever made any direct comparisons with RHS/AM74 and FX39? Both are said to provide sharp negatives.
I want to try something sold as a liquid concentrate for a change rather than a developer sold as a dry powder to make a stock solution.

Re: Spur PDX & Rollei RPX-D.

Both Rollei RPX-D and Rollei Supergrain are SPUR products. RPX-D has been made especially for pushing the Rollei RPX-100/400 films. Rollei Supergrain is an almost 1:1 copy of the Amaloco AM74 developer which was sold by Rollei-Maco before 2008 (when Amaloco Photochemicals the Netherlands closed the...

Re: Spur PDX & Rollei RPX-D.

I found the times for Rollei RPX-D here, but only for one Ilford film and two Kodak films. Unless the developer comes with starting times for the full range of those manufacturers films, then I will not bother with it. This developer appears to be the same as Rollei RHS developer, but at a much lowe...

Spur PDX & Rollei RPX-D.

Are these two developers one and the same and is there a developing time chart available for them?

I didn't see anything about them on the massive dev chart.

Minox Compact Camera.

I thought I would post this link to a short film made by PentaxPete. The latter part shows some prints he made with this camera using Ilford Delta 100 developed in home made FX37. https://www.youtube.com/watch?v=vJGXxdNKMBo&feature=youtu.be Thanks for making this Pete as the Minox 35 GT looks like a...

What dev times are you using with FX39?

These images from films developed in FX39 look good.

Re: Anyone tried the new 'Promicrol'?

Good news: Klaus Wehner from Paderborn (Germany) found a synthetic chemical alternative and made a modified Agfa Atomal, ATM-W (Atomal from Wehner).
