General method is to dissolve the chemicals in the order listed into about 750ml of water at about 25°C (80°F). Make sure that the chemicals are fully dissolved before adding the next one. Once all the chemicals have been added, make the mix up to 1 Litre by adding more water.

I weigh the chemicals one at a time using a small set of scales that are accurate to 0.1 gram. Measuring small quantities may be awkward especially where fractions of a gram are specified. You can get reasonable results by 'cutting' the chemical. 'Cutting' involves weighing out four times the amount required then pouring the powder onto a flat surface, e.g. a small piece of glass and forming it into an even square. Using a piece of stiff card, divide the chemical into four across the diagonals, each quarter will weigh the correct amount.


Developers containing metol may oxidise - this may be prevented by dissolving a pea sized amount of sodium sulphite in the water BEFORE adding any chemicals.

All weights are in grams (g)

This is essentially the same as normal D-76/ID-11 but is more stable with time, i.e. it has a longer shelf life - it will not process more films per litre.

Once mixed, keep sealed in a cool cupboard and it should stay fresh for at least three months.

Comments needed on this one.


Being unadventerous and conservative I have only ever used ID-11/D-76 and have only strayed outside of the film makers recommendations by accident. I have not used any of the other developer formula described here and as such feel unable to describe their properties. If anybody feels as if they can provide a good description then please do and I will incorporate here.

If you have a formula that is not included here and would like it to be, then please email me (dave THE_AT_SIGN restall.net) with the details and a description and I will include it in the list.

Note that these mixes have a shelf life and are hazardous especially if swallowed. For this reason all chemicals must be correctly handled, labelled and stored in such a manner that prevents inadvertent access.

I store my mix on a high shelf in a darkened cupboard. The bottle top is labelled with what is in it. My kids are sensible and not interested and these precautions are enough - your kids may be different but no less precious so please be careful.

To extend the shelf life, I store in a concertina bottle available from Jessops.

I bought my raw chemicals from Silverprint (Sorry their site uses frames so I can't link directly) in the UK. Rayco also supply chemicals but I have been unable to contact them. I would prefer to use Rayco because their site was nice and simple, unfortunately it has now gone, Their telephone number is +44 (0) 1226 744594 and if you have any luck let me know.
