246 THE <strong>DARKROOM</strong> <strong>COOKBOOK</strong><br />

STOCK SOLUTION A<br />

Water at 110F/43C, 750.0 ml<br />

Metol, 3.0 g<br />

Sodium sulfi te, 40.0 g<br />

Hydroquinone, 12.0 g<br />

Sodium carbonate, monohydrate, 75.0 g<br />

Potassium bromide, 0.8 g<br />

Water to make 1.0 liter<br />

STOCK SOLUTION B<br />

Benzotriazole, 1% solution<br />

Dilute 1:2 and add between 6.0 ml and 15.0 ml of Stock Solution B per each liter of Stock<br />

Solution A used. <strong>The</strong> more benzotriazole the greater the blue density.<br />

FORMULA #71<br />

Defender 54-D<br />

<strong>The</strong> effects of this formula on paper color are subtle with most modern emulsions.<br />

Water at 110F/43C, 750.0 ml<br />

Metol, 2.7 g<br />

Sodium sulfi te, 40.0 g<br />

Hydroquinone, 10.6 g<br />

*Sodium carbonate, anhydrous, 75.0 g<br />

Potassium bromide, 0.8 g<br />

Water to make 1.0 liter<br />

* Sodium carbonate, monohydrate, 88.0 g.<br />

Dilute 1:2.<br />

FORMULA #72<br />

W130B<br />

(John Wimberley)<br />

According to some photographers Ansco 130 gives an unmatched tonal richness. By changing<br />

the restrainer from potassium bromide to benzotriazole, W130B achieves cooler tones. <strong>The</strong><br />

quantity of benzotriazole given in this formula is higher than the minimum needed to prevent<br />

fog, preventing density shifts in the fi rst few prints and slightly increasing tonal separation in<br />

highlights.<br />

Water at 125/52C, 750.0 ml<br />

Metol, 2.2 g<br />

Sodium sulfi te, anhydrous, 50.0 g<br />

Hydroquinone, 11.0 g<br />

Sodium carbonate, monohydrate, 78.0 g
