B&W Film Developers and Emulsions
D-19 high contrast black & white developer is well suited for glass plate development. It produces a dense, high contrast negative suitable for printing in alternative processes such as Platinum/Palladium and Albumen, as well as silver gelatin papers. 1 liter will develop about forty (40) 4"x5" negatives. Use undiluted for 4.5 minutes at 70* F, agitating every 30 seconds.
A modified PMK formula with Ascorbic Acid (Vitamin C) added as an anti-oxidant. Ideal for Jobo and other rotary film processors. Makes 33 liters.
Based on Hutching's formula. Kit makes 50 liters of working solution. You receive: 500 ml PMK Pyro "A" Solution 1000 ml PMK Pyro "B" Solution
Pyrocatechol-based developer produces similar results to PMK or Rollo Pyro pyro developers. Produces a brown stain instead of the typical green stain left by traditional pyro development. Kit makes 50 liters of working solution. Contains: 500 ml "A" solution and 500 ml "B" solution.
MAX PYRO-Makes 10 liters. The new developer from Gordon Hutchings, author of The Book of Pyro. MAX PYRO is a pyrogallic acid developer that can be used with all black and white films and all developing methods, jobo-style developing tanks, tray developing, and stainles steel hangers.
Liquid Light© is a black & white photographic emulsion for prints on wood, glass, ceramics, plastics, china, fabric, metal, rock, paper, artist’s canvas, walls, any surface. Printing with Liquid Light is the same as with black-and-white enlargement paper. Under amber or red safelight, brush the emulsion onto a surface. Expose with an enlarger or slide projector. Process with standard paper developer and fixer. Prints are archivally-permanent with a full range of tones and transparent highlights that reveal the color and texture of the material underneath.
- Safe to use: Rockland emulsions are non-flammable and odorless with no phenol or VOC's (volatile organic compounds) and are completely safe for use in darkrooms.
- Long Shelf Life: They stay fog-free for years. To assure reliability, the shelf life is stamped on the package.
- Darkroom Sensitivity: They are fast enough for big enlargements but not over-sensitive to safelight exposure during coating and drying. Nothing has to be added before use.
- Controllable Contrast: Contrast is medium high-- about the equivalent a #3 paper. Lower contrast can be obtained by using a soft-acting developer.
- Coverage: High silver content allows one ounce of emulsion to cover one and a half square feet. Example: 32 ounces (quart) sensitizes up to 48 square feet.
- Non-Yellowing: They leave absolutely clear highlights with no discoloration.
- Optical Brighteners: They contain optical brighteners to give extra snap to highlights.
- Permanence: Prints made with Liquid Light and Ag-Plus emulsion are truly archival due to the colloidal silver image, and will not fade if properly processed.
