Zebra 5×7 Black Glass Dry Plates (Pack of 10)
Zebra 5×7 Black Glass Dry Plates combine precision-manufactured opaque black glass with ultra fine-grain silver gelatine emulsion to produce beautiful, high-contrast direct positives.
The completely opaque black substrate enhances:
- Deep tonal richness
• Bright, clean highlights
• Strong visual separation
• Zero light bleed-through
Each plate is machine-coated for perfectly even emulsion thickness, consistent sensitivity, and repeatable professional results. The smooth, defect-free glass ensures uniform image formation and reliable handling in standard 5×7 holders.
These plates are delivered ready to expose and process no additional coating required.
Direct Positive Processing
Standard silver gelatin development produces a negative image. To achieve a direct positive on black glass, the developer is modified by adding Ammonium Thiocyanate, which allows the image to render bright against the deep black background.
Ammonium Thiocyanate is available as part of our regular Darkroom Chemistry range, enabling a complete and controlled workflow.
Box contains:
• 10 × Zebra 5×7 Black Glass Dry Plates
• Machine-coated ultra fine-grain silver gelatine emulsion
Engineered for photographers and artists seeking tonal depth, material precision, and consistent direct positive results.
