Bergger Prestige CB Art, Grade 4, exposed for 28.2 seconds at f/8 and developed 50 seconds in Ansco 120 (2:1) at 68º F, then washed briefly before being moved to a solution of Ansco 120 (1:2) with 30 grams potassium bromide added, and solarized for 4 seconds with a 55 watt incandescent bulb 4 feet above the tray.  Development was continued for an additional 70 seconds in the second tray of developer. 

After development the print was stopped with acetic acid and fixed for 45 seconds each in two baths of rapid fixer.  The print was moved directly from the fixer into a solution of Farmer’s Reducer for prints and reduced for 60 seconds, rinsed briefly, then returned to the fix for 30 seconds.  The print was toned for 2 minutes in selenium toner (1:15), followed by a 3 minute wash, 3 minutes in hypo clearing agent, and a 1 hour wash.

Test strip unreduced.  28.2 seconds was chosen for the development time. 

Same test strip.  Reduced for 30 seconds in iodine reducer (1: 128).  Upper half toned in Dupont 6T (6 grams potassium thiocyanate, 3 milliliters 1% gold chloride in 1 liter of water).

Bergger Prestige CB Art, Grade 4, exposed in strips for 40 seconds, 48.4 seconds, and 60 seconds at f/8 and developed 50 seconds in Ansco 120 (2:1) at 68º F, then washed briefly before being moved to a solution of Ansco 120 (1:2) with 30 grams potassium bromide added, and solarized for 4 seconds with a 55 watt incandescent bulb 4 feet above the tray.  Development was continued for an additional 70 seconds in the second tray of developer.  40 seconds was chosen for the development time of the fine print (see below). The test strip was reduced in Farmer’s Reducer for prints for 60 seconds, rinsed briefly, then returned to the fix for 30 seconds.

Below is the same test strip reduced in iodine reducer and toned in three different toners.
