A most effective and energetic solution

[pdeeh]

A friend has just been looking through a box of old photography booklets and manuals, probably once belonging to her grandfather.

In "Profitable Press Photography" by Ernest Oakley (Matson's Publications, 25 Sussex Street, Cambridge, ?1931, Price: One Shilling) we find the following, which I thought I would share so that we are all up-to-date with the latest in developer technology ...

A USEFUL DEVELOPER

For Press work no better developer for plates and films can be recommended than Pyro Metol. This forms a most effective and energetic solution. It gives high speed and good density.

The following formula is a good one :

1.
Metol 20 grs.
Metabisulphite 60 grs.
Pyro 25
Water • • • 10 ozs.
2.
Carbonate of Soda 2 ozs.
Water • • 10 ozs.

For use take equal parts of one and two.

For bromide papers any good Metol Hydrokinone developer may be used.

The following is an excellent formula :

Metol ••• ... 25 grs.
Sulphite ... ... 200
Carbonate... • • ... 200
Hydrokinone • • • ... 20
Bromide ... • • • ... 15
Water • • • ... 10 ozs.

Besides keeping well, it gives great contrast and clear whites on any good make of bromide paper.
