8 commercial developer replacements

I got to thinking what home-brew alternatives could one use for commercial developers? Here's some ideas. What do you think?

1. Xtol/DDX

This one's easy for me! FX-55, perhaps Geoffrey Crawley's last public formula released in conjunction with Amateur Photographer magazine, it's the perfect replacement for these two commercial Ascorbate developers. It's fine grained, low toxicity, and makes beautiful negatives. Simple to make, this developer will save you money and make cracking negatives to print.

To use, take 100ml of stock part A and dilute to make 1 Ltr of working solution. Then add the dry developing agents to the 1 Ltr of working solution to create the viable developer. It keeps for up to 36 hours but then must be discarded.

For an idea of developing times start tests at 7 minutes@20c. Don't test with important negatives!

Part A Stock

Sodium Carbonate Anhyd. 15.4g (Mr Crawley said 20g of Potassium Carbonate but I find that harder to get)

Sodium Bicarbonate 1.5g

Sodium Sulphite 25g

Sodium MetaBiSulphite 12g

Water to 1Ltr

Part B

Sodium L-ascorbate 1.3g

Phenidone 0.1g

2. HC110/Rodinal/Ilfotec

HC110 and Rodinal are often quoted as having long keeping qualities and can both be used at great dilutions. Rodinal is also renowned for its sharpness and its compensating effects, especially with stand and semi-stand techniques. 510-pyro is the perfect substitute with its long lasting quality. It can be used at 1:100 dilution right up to 1:500 and produces some of the nicest tonal range I've ever seen in a print. The grain is much finer than Rodinal and somewhat finer than HC110 so if it's grain your after you'll have to use a faster film. However, 510 gives the same edge effects that Rodinal is so good at and also those long stand development times that means you can develop films of different iso in the same batch. Highly recommended!

510-pyro

Hot TEA (Triethanolamine) 75ml

Ascorbic acid 5g

Pyrogallol 10g (wear mask and gloves and take care as this must not be inhaled!)

Phenidone 0.25g

TEA to make 100ml

Note: It can take a long time to dissolve the phenidone

To test your film try diluting 1+200 and develop for 12 minutes at 20c. Again, don't test with important negatives!

3. Ilfosol/D-76/Perceptol

D-23 without question. Pretty similar results I'd say and a lot cheaper. Easy to make and just as versatile. I've written about D-23 a lot in other blog posts. you'll get tons of times from the Massive Development Chart.

750ml warm water

7.5g Metol

100g Sodium sulphite

Water to 1 ltr

So, that's a stab at alternatives to commercial products. you'll probably know where your favourite brew fits into this. but I'm curious? What's your idea of alternatives made in the darkroom?

The Exakta may be the reason Nikon developed the F – to move the professional SLR that this mishmash of old and new technology had become, into a modern marvel that would influence SLR design for decades.
