Write first reviewSilberra is a somewhat controversial analog photography brand from Russia. It was founded in 2017 and currently produces several new black-and-white negative films. Getting these films to Europe was an adventure on its own so only limited quantities are available for now.
Silberra ORTA50 is a new hi-resolution orthochromatic black-and-white negative film made in Russia with a low nominal film speed of ISO 50.
The film's emulsion was initially designed for optical printing which makes that the film can be processed under the same red safelight as the processing of photographic black-and-white papers. Due to the comparatively high sensitivity of the film it is however still important to make sure that safelight is far enough.
Processing times in the most common film developers (20 °C):
Developer | Dilution | Time |
D-76 | 1+1 | 7 ½ min |
ID-11 | 1+1 | 7 ½ min |
XTOL | 1+1 | 7 min |
Constant agitation for the first 30 seconds and then 5 seconds at the start of each following minute is recommended!
| Film size | 35mm Film |
| Film type | Black-and-white negative |
| Film speed | ISO 50 |
| Number of exposures | 36 exposures |
| Contrast | High |
| Grain | Fine |
| Development process | Black-and-white |
