Beers Formula
The Beers formula: -
Bath A Water 750ml at 52ºC Metol 8g Sodium Sulphite 23g Sodium Carbonate 21g Potassium Bromide 11.0ml (10% Solution) Water to make 1litre Bath B Water 750ml at 52ºC Hydroquinone 8g Sodium Sulphite 23g Sodium Carbonate 27g Potassium Bromide 22.0 (10% Solution) Water to make 1litre All chemicals are anhydrous. The above can be mixed in various ratio's of A & B to create a single bath developer with differing contrasts. For use as a two bath developer John Blakemore suggests the following: - Lowest Contrast 1 Part A + 1 Part water (no Part B) Highest Contrast 7 Parts B + 1 Part A (no water) Varying the time the print is in each bath will allow fine tuning of the contrast With thanks to John Blakemore's "Black and White Photography Workshop" and "The Darkroom Cookbook". John has quite detailed information regarding this developer in his book, if you are interested in this formula I recommend that you read it.

Thanks for that Barry. I've got 'The Darkroom Cookbook' with tehe recipe, but there is little detail of how to use it. I intend to get John Blakemore's book ASAP.
I suspect the Fotospeed Grade Select was pretty much the same as Beers - the dilutions look similar. I've got all the reqired chems. and I've got a day in the darkroom Tuesday, so hopefully I can post a few results soon. Rob |

I've just posted a couple of images:
http://www.film-and-darkroom-user.or...&pictureid=775 and: http://www.film-and-darkroom-user.or...&pictureid=753 I was really impressed with the variation I could achieve with Beers. I reckon I can get about Grade 1 to 3 with Kentmere Bromide Grade 2. I can see me using this quite a bit. Anybody know what the keeping qualities are like with Beers? Rob |

Good to hear that its working for you Rob, particularly with Kentmere Bromide. I also want to try more contact prints with this paper.
I would use it more if I had the space! I understand that it has very good keeping qualities. I have no figures though?

Digitaltruth states the following:
"The stock solutions are diluted 1:1 to obtain the working solution. The shelf life of the stock solution is 3 to 4 months, but the working solution must be discarded at the end of the working session." I've used it years ago, but can't remember much about its keeping properties. Will give it a try again and see.

Imbued with the spirit of adventure as a result of Barry posting the Beers formula, I set about a few experiments yesterday.
I hadn't used a two-bath since 198...something, and then I think it would have been something like Ansco 120 and another I can't remember. Maybe it was Selectol and Selectol Soft, who knows. Anyway, for the sake of this thread I've put my initial test on a little web page, showing the results with #1 mix and #6 mix on Adox Nuance Grade 3. Here are the comparison images, click these to be taken to the page, where there is a more useful way of comparing the results. The final print made utilised both #1 and #6 mixes, moving the print between the two in a way that I could probably never repeat! You can see that in the Discussion/Help gallery here. I'm not 100% happy with it yet and comments are welcome.
