Hi :)

After making my first self-made developer (ORWO-19, the modified D-76) I`m planning to make and test A49. The problem is...I can`t find a good recipe anywhere. Those I found are much different...any clues?

The A-49 from Calbe seems to be still in production. Concerning the price it's very cheap.
It's a modified form from Agfa FF Atomal.

A49 can be also bought in my city, but I want to make it myself if possible :)

(It`s cheaper`s fun! )

Dear Dziadek :) I used A49/Atomal ..I managed to obtained best results with Kodak Tx400@320 and Kodak Plus-X @100 with 1:1 dilution at 21C and 10-11min, agitating continuously for first minute and then 2 turns per minute. Examples: Ex1 and Ex2 Also, It works well in push process: Ex3 I hope this helps.

Nice :)

I will give up anyway...for now :) I found the recipe but I can`t find one of the main ingridients: Hydroxyethyl-o-aminophenol anywhere. Maybe it hase a more simple name... I`ll be patient in my searches :)

I know that A49 can be bought in a shop, but making chems at home is fun :)

2(beta-hydroxyethyl) aminophenol sulphate (aka HEAP sulfate), is no longer in production anywhere in the world. It was a main ingredient in Promicrol from May & Baker. It was the best speed increasing fine grain developer.
I think it was used in the original Agfa FF Atomal too. So later (Calbe) also had to change their formulae.

But if you are looking for ultra fine grain developers:
Microdol-X (discontinued by Kodak)
Perceptol (1 ltr. ilford packing)
CG-512/RLS 250ml/1ltr. Udo Raffay reference developer, CG, Rollei
W665 (Windisch) based on Ortho Phenylene Diamine. Discription in "die Neue Foto-Schule - 1941 - " Ingredients are still available.

But the replication of the original Promicrol and/or FF Atomal is impossible.

So now it makes sense. I have a feeling that it was banned by those crazy eco-terrorists. Am I right? ;]
Fotohuis (Robert) 8 years ago
Due to EU-GHS, the new European law for chemical materials, it will be very difficult to get seperate materials in the near future.

About HEAP sulfate, it's maybe 15 years ago about the May & Baker Promicrol.

Maybe the EU is also killing now the last photochemical business.
brown sheet [deleted] 8 years ago
Another detail, which makes me dislike the EU. People should have a right to choose if they protect the natural environment or not. Instead of banning anything (i.e the good, traditional light-bulbs) by force, they should launch a big informational/public campaign, which informs about the dangers of pollution etc.

Dziadek, it's not about pollution and other dangers, it's all about benefits - appointed and liaisoned companies who are ready to save the world.. :]

What I found for Atomal (not FF):

It is important not to confuse Atomal with Atomal FF wich are totally different developers. Atomal is the fine one. The exact formula for Agfa Atomal is the following:

Package A:
Oxyethyl-ortho-aminophenol 6g
Pyrocatechin 10g
Hydroquinone 4g

Package B:
Sodiumsulfite sicc. 100g
Sodiumcarbonate sicc. 25g
Potassiumbromide 1g
Sodiummetaphosphate 1g

Dissolve in 750 ml of water of 50° Celsius. Cold Water to make 1

This formula was published after world war II by an investigation comission of the allied forces that also published other Agfa formulas
like Rodinal. Later published in No. 3019 “Amateur Photographer” 1946.

In my attempt to mix this formula I asked at Agfa if the formula was right. I was told that AGFA cannot confirm this formula (of course it’s the companie’s secret). But they confirmed that the Ingredients are right. I expect this formula to be right. The problem is the main developing agent oxyethyl-ortho-aminophenol. Agfa reported me, that in the past they ordered this derivate at Merck, a German pharmaceutic company. In fact, I don’t know where to get this agent. Maybe it can be replaced by some Color Developer like Kodak CD2.

I think Atomal was one of the finest BW developers ever formulated with a beautiful gadation and some subtle staining effect providing full film speed and substantial fine grain. If someone knows where to order the right developer agent I would be happy to be informed.

Note from me: CD2 is not available anymore. It was a component of Amaloco K54 mononegacolor (C41) kit which can not produced anymore due to the lack of CD2.

About original M&B Promicrol:

Speed-increasing film developer
Water, 125F/52C 750 ml
2(beta-hydroxyethyl) aminophenol sulphate 6 g
Glycin 1.13 g
Sodium Sulfite (anhydrous) 100 g
Sodium Carbonate (anhydrous) 11.5 g
Sodium Hexametaphosphate 1.7 g
Cold water to make 1L

Mixing instructions: Add chemicals in specified sequence.

Dilution: 1+9, 1+14

Notes: Promicrol is considered by many to be one of the best speed-increasing developers ever made. Sadly, one of its key ingredients, 2(beta-hydroxyethyl) aminophenol sulphate (aka HEAP sulfate), is no longer in production anywhere in the world. Current commercial products sold under the name Promicrol or claiming to be similar to Promicrol, are not comparable to this formula.

Sound very interesting :) I think I saw Oxyethyl-ortho-aminophenol somewhere during my searches in a catalogue or something, because it rings a bell and sounds familiar :)

As for Promicrol...i found something like this:

It`s labeled with a star (which means: difficult to get - the shop must make an order), but maybe it`s still possible to get, altough I belive it`s not as good as the original :)

I just clicked on that 'link' and in the picture was a bottle of the liquid 'Promicrol' sold by Champion PhotoChemistry Company -- I have THREE 1 litre bottles of it given to me by a staff member of Champion some years ago when they had a sales outlet in my town and I asked about the powder Promicrol and they told me about the 'HEAP Sulphate' being 'Carcenogenic' and the workers in the factory where it was made refused to make it any more -- years ago 1958 I got a job at May & Baker factory in Dagenham in the Biological Research Building and one of my old School friends had a job in the Photographic Quality Control and used to test batches of the 'real' Promicrol -- he would work on part A one week then part B the next week and would save un-opened packets of A then give me some packets of B the next week and I had FREE Promicrol until I left to get a job in Photography !

@Dziadek1912 - I have been to this store an hour ago. They still keep the 1l. bottle of Promicrol by Champion. I guess that's the same bottle I saw there few months ago.

That`s good to know :) I`m working on my first display in my hometown. More things done mysfelf (chems, negatives, prints), the better effect and satisfaction :)

Just looking for something that gives very fine grain (prints will be at least 30x40cm) on Kodak materials.
superb horn [deleted] Posted 8 years ago. Edited by superb horn (member) 8 years ago
My picks (I'm also a Kodak film burner) for TX and PX are: A49/Atomal 1:1, Ilfotec DDX 1:9 and Prescysol 1:5:100 (by Peter Hogan, staining dev) ..I'm still thinking how to use HC-110 especially for evening/night shots on TX 400-1600.

I read somewhere..(heck, I forgot where, thou!) that A.Adams used old Kodak PX with HC-110 1:90 ...maybe somebody could verify that info?
Fotohuis (Robert) 8 years ago
Para- or Ortho Phenylene Diamines will give the smallest grain possible.
W665 (Windisch) (Ortho-) or 777 Panthermic (Para-) are the best examples of it.

Mentioned alternatives: Perceptol, CG-512/RLS or indeed staining developers like PMK, Finol (Moersch-Germany) or indeed Prescysol.
Indeed: HEAP is carcenogenic but also Pyrocatechine and Pyrogallol (used in staining developers) are not very healthy.
superb horn [deleted] 8 years ago
I may only add.. that the advantage of Prescysol or Finol is that it's already liquid - so one doesn't need to take any extra precautions playing with powder..
Fotohuis (Robert) Posted 8 years ago. Edited by Fotohuis (Robert) (member) 8 years ago
Playing with powders on staining developers is a very bad idea. And when making a choice for Phenylene Diamine: The Ortho version is much less toxid and non-staining. So W665 is better when going for an experiment.

In the mean time Klause Wehner (Paderborn, Germany) made an equivalent Agfa Atomal with a synthetic HEAP equivalent. It is called ATM-W. Here an example of Rollei RPX-400 E.I. 400 in ATM-W. 20 minutes at 22C in rotary (CPA-2 Jobo). Zorki-6 with J-9 lens. It combines sharpness, full box speed and fine grain.

BTW it is almost the same formula as Rodinal Special but that was in a Glykol base just like HC-110.
