Photographers Formulary 130 paper developer very dark

[eli griggs]

I happen to use 130 at 1:3 dilution, giving me enough for an oversize 16X20 tray. So I'll give you the formula for 500 ml of stock solution. Simply double that for a full liter of undilute stock solution if that works out better for your own needs.

hot water 350 ml
metol 1 g
sodium sulfite 25 g
hydroquinone 5 g
sodium carbonate mono 40 g
fresh glycin 5 g
water to raise total volume to 500 ml

(As usual, add a tiny pinch of sodium sulfite to the hot water first, prior to the metol).

Cheers!

This is going to be useful in checking out out of date glycin powders for go/no go purposes.

Godspeed
