Hi All,

I am having some difficulties in finding Agfa (Rodinal) Developer in my country and also it is not being shiped from USA, as the chemical is hazardous, but i can get all Kodak developers in my country, could any one tell me which is equivlent to Agfa's Rodinal Developer in Kodak.

 

<p>

 

Regards to All

There ain't one. Rodinal is unique.<br>The formulation is basically a

Paraminophenol developing agent coupled with a Potassium Hydroxide

activator. It's the Potassium Hydroxide that's hazardous, and Rodinal

concentrate is extremely caustic. Try getting it shipped direct from

Agfa in Europe.

As Pete stated, Rodinal is a unique developer and you might have

better luck acquiring it through European sources. Calumet has

offices in the UK and perhaps they can ship it (calumetphoto.com.)

If you're looking for an alternative to Rodinal in a Kodak

formulation, try HC-100. It is in no way like Rodinal, but the

results on film "could" be similar. There will be no similarity in

dilutions. The Darkroom Cookbook, by Anchell & Troop list a formula

for a Rodinal "type" developer, but the actual formulation is

proprietary.

You could ty mixing up traditional Rodinal. Solution A: take 750 ml

water at about 52C, add 100gms of p-aminophenol hydrochloride, 300

gms of potassium metabisulfite and add water to make 1 litre.

Solution B: Take 300 ml of COLD water, add 200 gms of Potassium

hydroxide and cold water to make 400ml. Potassium hydroxide gives off

a lot of heat when going into solution - the water could start

boiling and splattering. Always add the hydroxide to water (and never

water to hydroxide). Use extreme caution.

When solution A cools, it will form a precipitate. Place Solution A

in an iced water bath and with continuous mixing, add 280 ml of

solution B until a sudden darkening in colour takes place. Continue

adding B drop by drop till most of the precipitate has dissolved.

Good luck, DJ.

Rodinal is not particularly hazardous, but it appears that some

retailers like B&H Photo are not shipping any liquid chemicals, even

within the USA. This is because the shipping companies are now

enforcing laws that were not enforced previously. Often times, the

laws deal only with labeling and reporting requirements, but their

current computer systems can�t handle it.
