The developer is suitable for push processes
Classic phenidone is a hydroquinone fine-grained developer for b/w photographic films (per 1 liter of working solution).
Allows you to increase the nominal sensitivity of the negative by an order of magnitude. Visually reduces grain and contrast even at high ISO values.
Ideal for the push process.
Preparation
It is desirable to prepare the developer on distilled water.
1. Dissolve the contents of a small package in 700 ml of water 50-55 °C. The package should be rinsed from the inside with a small amount of warm water and drained into a working solution.
2. After completely dissolving the small package, dissolve the contents of the large one. It is also advisable to rinse a large package with water from the inside. 3. Bring the volume of water to 1 liter and cool the solution to operating temperature. Before use, it is advisable to let the developer infuse for several hours. Filter if necessary.Processing conditions
To process the film according to the nominal sensitivity, it is desirable to dilute the working solution with 1 + 1 water. An undiluted working solution (drain) is better suited for the push process. Processing time: see summary table on digitaltruth.com
Usage limit
Up to 7-8 "narrow" films of type 135/36 can be processed in 1 liter of developer.
Storage conditions
Store in a dark, cool place. In dry form, the developer is stored for at least 1 year. Working solution - at least 1 month in a tightly closed container filled under the throat. The partially used solution is not stored.
