FORMULA #32
FX 1 (1961)
Formulas 221
(Geoffrey Crawley)
This developer was formulated for maximum acutance with conventional medium- and slowspeed
fi lms. It is not recommended for fast fi lms or for tabular grain fi lms.
Water at 125F/52C, 500.0 ml
Metol, 0.5 g
Sodium sulfi te, 5.0 g
Sodium carbonate, anhydrous, 2.5 g
*Potassium iodide, 0.001% solution, 5.0 ml
Water to make 1.0 liter
* To make a 0.001% solution of potassium iodide, add 1.0 gram to 1.0 liter of water. Take 100.0 ml
of this solution and dilute to 1.0 liter. Again take 100.0 ml of this solution and dilute to 1.0 liter
(this is equal to 1.0 mg per 100.0 ml).
Use undiluted. Developing time is between 7 and 14 minutes at 68F/20C.
FORMULA #33
GSD-10
(Jay DeFehr; thanks to Mark Booth)
GSD-10 is formulated for slow fi ne grain fi lms like Kodak T-Max 100, Fuji Acros 100, and Ilford
Delta 100 but can also be used with fi lms ranging from slow document- type and ortho fi lms,
to IR.
This high acutance formula is especially suited for stand development and minimal agitation
techniques, although normal intermittent agitation and rotary processing may be used.
