Re: Beseler 67 negative holder

You are correct, the 23C has round holders. I have seen the square holders on occasion but thought they were for Omega B22 enlargers. If I come across any I'll let you know.

Re: Beseler 67 negative holder

I just located a 6x4.5, 6x6, and 6x9 neg carrier for the Beseler 23C, which I believe is the same as the Beseler 67 in Europe. Send your shipping address to sgaphotog@gmail.com. I'll try one more time to see if I can find a 6x7.

Errata: it was the formula for Edwal Super 20 that I received from someone at Edwal. I never had the formula for FG7.

Re: dissolving phenidone

Alternately, you could allow the Phenidone to sit overnight in room temperature water and drink the Vodka. Stir occasionally and use olives.

Re: Septic & well water

It depends on the photo chemicals. As mentioned, avoid the caustic chemicals at either end of the pH spectrum and anything with mercury. Use common sense and avoid anything that you're not sure of. For the most part, b/w photo chemicals are photo grade versions of chemicals that are found around you...

Re: Septic & well water

From the Darkroom Cookbook, 4th Ed. Septic Systems There is very little written about darkroom chemicals and septic systems. Fortunately, Kodak did a lot of research on this subject, even though it is not always easy to find. Most chemicals for the black and white darkroom are organic and photo grad...

Re: Omega D5-XL, corners dark on 4x5

Greetings, Tim. I have been using the D5-XL for more years than I can recount. I have owned several. It's not the best enlarger ever made but it's my personal favorite. I have not experienced the corner fall-off that you have. What tests have you run? For example, take a reading without the condense...

I have not used any of these developers. The best thing is to pick one and test it with your film of choice.

Re: Developer: Better than Microdol-X??

This is a very interesting question and one that I am often asked: How can I replicate a particular photographer's "look?" The simple answer is: You can't. Films made before 1960 are not the same as films made during the period between 1960 and the introduction of flat grain technology, and even fla...

Partly. It is also to make certain you achieve full and complete development on every frame regardless of how much exposure was received.

Re: Paterson System 4 question

Sverre, I recommend Paterson System tanks, regardless of size. I have, and use Paterson tanks from 2-35mm reels to 8-35mm reels. Just make certain you don't overload them. Remember, it is important to have as near 350ml of working developer per roll as possible - more being better.

Re: Dr. Roland F Beers variable contrast paper developer

The Beers formula was being used to alter contrast on graded paper since Ansel was wearing knee pants. I have seen it published in numerous older texts but not one of them has been written by Dr. Beers, they are all simply reproductions of his formula. And you are correct, they may not be the origin...

Re: Dr. Roland F Beers variable contrast paper developer

My response to this post was slightly rushed last night. What I failed to mention is that Beers formula has been around for a very long time, and was in use when I began my career in 1970. In the 1983 version of The Print, Ansel Adams mentions it in three places in the text and provides the formula ...

Re: Edwal FG-7

I, too, was a great fan of FG-7.

The formula was proprietary and Edwal never published it. Someone at Edwal did give me a version that they said was authentic, but the formula did not make much sense to me. It is published in one of the earlier versions of the DCB.

Saludos, Jesus. If it is simply the formula you're after you can also find it on page 282-283 of DCB4 or p. 287 of DCB3, as payral suggests. There are two VC paper developers of which I am aware. Dr. Beers formula is the most well known and the one I learned in the '70s. The other is Kodak D-64, whi...

Re: dissolving phenidone

What could I use instead to dissolve Phenidone? Phenidone does not dissolve readily in water, but is relatively easy to dissolve in distilled water at a temperature of about 175F/80C. It is readily soluble in solutions of alkali bisulfites and carbonates. This allows it to be readily incorporated i...

Crawley's classic FX 37 formula uses 0.5 g of Phenidone. It is far easier to measure out 50 ml of the 1% solution to use in a liter of FX 37 than trying to accurately weigh 0.5 g each time. I've just been corrected by Bill Troop on this. Rather than trying to paraphrase what he said here is what he...

Re: D-23 Divided

BZT is most commonly used to reduce fog in high pH developers that contain Phenidone. That said, I can think of no practical reason not to at least try it in a test batch. It's action will be greater than that of bromide. Normally you would start with 1/10 the solution concentration of bromide, but ...
