Platinum II The Edwal top quality black and white print developer for home darkroom and studio use. On RC papers, Platinum II provides a neutral (not bluish) black image, and yields truly superior quality results with warm-tone fiber-base papers, providing a rich warm black. Standard contrast on cold-tone papers is produced with the usual liquid dilution. Same dilution on warm-tone papers gives a bit softer print. Diluting with more water will obtain softer results. Contrast can be increased slightly by diluting with less water (1:7).

T.S.T (with Solution B) Most versatile black and white paper developer available. TST Concentrate is accompanied by "Solution B". The use of "B" controls contrast on any paper. Tones ranging from high density cold images to warm portrait blacks are possible. 1 gallon of TST produces 12 gals. for heavy-duty applications; 16 gals. of commercial strength developer; 20 gals. portrait strength, and can develop over 4,000 - 8 x 10 prints. Has a working temperature range of 55-90°F.

G Developer The black and white print developer so convenient, it's ready to use right from the bottle. "G" is poured directly into the tray, then any developer left over goes back into the bottle. Newly opened developer can be combined with leftover solution without inhibiting its effectiveness. "G" will develop at temperatures ranging from 65º to 100ºF. Gives snappy blacks on both RC and fiber-based papers and can be used to punch up contrast. One quart develops 200 to 250 - 8 x 10 prints. Unopened, "G" has a shelf life of 5 years and up to 3 months in a bottle kept closed after use.
