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.

Re: Minox Compact Camera.

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). I am getting the new formulae next week in new type HD-Polyethylene bottles but some first tests and curve fittings are already available. Interesting...

Re: Increasing Exposure Latitude in B&W 35mm film

Another option of contrast control is to use two-bath development. The Leitz two-bath developer as given in The Ilford Manual Of Photography (1958) is of similar composition to D-23. Solution A; Metol 5g Sodium sulphite, anhydrous 100g Water to make 1 litre. Solution B; Sodium sulphite, anhydrous 6g...

Ken Keen.

This is a short film about a photographer who is nearly completely blind, but still taking photographs and making his own prints.
I found it very inspiring.

Re: Increasing Exposure Latitude in B&W 35mm film

Barry Thorton was a fan of Ilford Perceptol which uses Metol as the only developing agent. When diluted 1+3, Perceptol will give the results that Ornello has already mentioned.
Err towards the generous side with film exposure with this developer.

Re: Anyone tried the new 'Promicrol'?

Old Promicrol can be compared with Agfa Atomal were the same HEAP Sulphate was in. Alternative (more modern) Ascorbic Acid (Vit.C) type developers: FX-50, Ilfosol -S/-3, Xtol, Fomadon Excel W27 or PC-TEA. As far as I know only PC-TEA has a long shelf life of approx. 2-3 years. All, other type Vit.C...

Re: Anyone tried the new 'Promicrol'?

As I mentioned earlier in the thread, Champion Promicrol sold as a liquid concentrate is a totally different formula altogether from the original May & Baker Promicrol formula. Even if you can still get the HEAP-Sulphate (Atomal) developing agent, I have to ask what you think it can do that newer fo...
