Soemarko LC-1 Developer

Can anyone tell me the shelf life of the stock solutions for this developer? Assume a partially filled storage bottle.

Thanks,

Jon

Is there anyone out there using this developer? I was considering this instead of Rodinal, because of the shipping restrictions of Rodinal. I do not have a local dealer I can buy it from. I would be interested in any information anyone can give me about its use. If I am going to be buying the chemicals to brew my own, I would like to know how long it will last as stock solutions.

I have used this developer, but only with lith film. I've found that the stock solution lasts about a month. In the new edition of Christopher James's book he has a newer formula that seems to work better.

Thanks Dan, I do want to process lith film. That is the reason for the interest in this developer. I guess I will have to try to mix smaller batches, since I do not know if I can use up the quantities as shown. Thanks for the information!

Do you have a name for the Christopher Jame's book?

I will have to give it a try!

Does anyone have examples using this developer?

Can someone please post the new version of the LC-1 formula? Thanks.

Can someone please post the new version of the LC-1 formula? Thanks.

From The Book of Alternative Photographic Processes...Second Edition, page 100, by Christopher James:

750ml distilled water at 125F
4 g Metol
80 g Sodium sulfite
4 g Hydroquinone
20 g Sodium bisulfite
add distilled cold water to make 1 liter stock solution

For use, dilute 1:5 to 1:10...5 to 10 minutes at 75F

Suppose to similar to LC-1, diluted 2:3:5, but with more of both sodium compounds

Thanks for the new information. What makes this better than the original though? Other than it being a single stock solution, instead of parts A and B. Am I correct in assuming that it will be slower acting because of the increased Sodium bisulfite?

Not exactly sure -- lower contrast for making internegatives, I believe. Might be for greater consistancy...but that's a guess.
