Why I chose D23 for all these years?

The tale of the dying developers

My father would remember longingly of when Johnsons of Hendon made one of the best developers around; Definol, a fine-grained acutance developer. He would reminisce of using it for years and really getting to understand how to get the best out of it. Then, without warning, Johnsons ceased production. Little did I know a similar thing was about to happen to me.

I started learning from him how to make my own developers. I was very young, and it was fun at first. But, as I took more pictures I became bored with always mixing chemicals and so I looked around for an easier answer. I decided on using the Patterson chemistry of the time. Geoffrey Crawley formulated many of the Patterson developers and he knew a good formula when he made one! Acutol and Acufine were two of my favourites and I got to know them well. Then boom, Paterson stopped making their developers.

Ok I thought, time to look around again. I always liked the results of pyro and pyrocatechin developing agents and learned of the excellent Dixactol Ultra from an article by Barry Thornton in Amateur Photographer. I learned to use it well and began to make beautiful negatives again but, boom; it disappeared with Barry’s tragic untimely death and was for a long time unavailable.

Reality dawned

I finally began to see what was happening. I knew I could no longer trust that my favourite brews would be there for me. Companies fold, or profits reassessed and low profit developers removed from production. The big companies like Kodak, Ilford, Patterson, and Johnsons never published the formulas, as they had done in the golden age. They discontinued their products, and the developers disappeared from the shelves, never to be seen again. I lost all that hard work learning the developer. I needed a plan, a much better plan.

One day I was reading a book by Eddy Euphraums and admiring his amazing photographs. In the back I noticed he was sometimes using home brew developers. He listed a few for the reader to try. I’d made my own developers for years. It wasn’t hard, and I knew that they wouldn’t go away like my trusted Acutol or Dixactol. Time for me to focus on some I knew best.

Keeping it simple

I wanted to keep it simple. I knew that D-76 was the standard to compare all developers to. Not great, but very good, good enough that every film produced must work well with it. The bottom line, if the film doesn’t perform well with D-76 then it will not fly with photographers. But D-76 is more complicated to make and more expensive than some others and so was there an alternative that was just as good, more economical and safe to make, simpler but dependable. The answer is yes, D-23.

5 reasons why I chose D-23

D-23 was in fact a better D-76 in every way.

1. It’s so easy to mix. With only two ingredients you can’t go wrong. Metol and Sodium sulphite, that’s it.

2. Always available. D-23 keeps well in a full stoppered bottle (or with some lighter gas - butane - gently sprayed in the bottle) and can be used for years with replenishment. But, if you don’t like that idea, and use it as a one shot, it’s so easy to mix you can make a new batch in a jiffy if required.

3. Great with all films. D-23 acts like D-76 and so works with modern and older emulsions - from Delta to FP4+. Some photographers have said it doesn’t give them the contrast they like, but this is because they’ve not developed the film for long enough. If you want more contrast increase development time, simple.

4. Compensating or fine grained. You can use D-23 stock solution to develop film for a fine grained negative or up to 1+3 for increased acutance (sharper) with added compensating effect. This is great for helping ensure that it does not blow your highlights with high contrast images. This makes D-23 a very versatile developer to use.

5. Easy replenishment. I’ve written about this before but it’s worth reiterating that D-23 is a great developer for using with replenishment techniques. To make the replenisher, you’d need Sodium metaborate * but with only that additional chemical you can use your D-23 for years.


Formulas:

D-23
500ml warm water
7.5g Metol
100g Sodium sulphite
Water to make 1ltr

Add a pinch of sulphite to the 500ml water before adding and fully dissolving the metol. Then add and dissolve the rest of the sulphite.

D-23 Replenisher
500ml warm water
10g Metol
100g Sodium sulphite
20g Sodium metaborate

Add a pinch of sulphite to the water before adding and fully dissolving the metol. The dissolve the rest of the sulphite followed by the metaborate.


* If you can’t purchase Sodium metaborate (as in the UK) then it’s easy to make. The 20gm of Sodium metaborate used above is made by mixing 14gm Borax + 3g Sodium Hydroxide in 150ml warm water. Use this solution to add to your replenisher.
