The Silberra ULTIMA100 is a black and white film. It is the Silberra brand under which the film stock can be found in stores. Silberra comes from Saint Petersburg, Russia. The material was probably produced by the Agfa company. There is also the Silberra PAN100, this is cast on a thicker base material, but is otherwise identical.
The Silberra ULTIMA100 is a film for monochrome images and is panchromatic sensitized. According to the manufacturer, the film speed is ISO 100.
The photos are advertised as having high sharpness and fine grain. Contrasts are rather moderate and it has a wide tonal range.
Development of the film
The ULTIMA100 needs to be developed in black-and-white photographic chemistry, and there are two options: development in photo labs or convenient development at home with the right accessories. The choice of developer has a significant impact on the final result.

It is not uncommon for developers to not have specific instructions for developing film of certain types. In such cases, it may be useful to create test strips to find the optimal settings for the desired film. The film strips containing the captured images are the result of the development process.
Development is usually followed by the creation of prints or digitization. Many labs also offer the ability to create prints in various sizes as an additional option during image development.
Digitizing
Digitizing film strips with a scanner presents itself as an option for processing photos in digital form. There are both professional photo scanners and scanners for home use in various price ranges that are suitable for digitizing negatives. After digitization, the files can be printed in various forms, for example as a poster or in a photo book, or shared on social media.
Formats
The ULTIMA100 is available in 35mm format only and allows up to 36 photos to be captured with one B&W film. There are a variety of manufacturers such as Zenit, Lomography, and Nikon that offer cameras specifically for the 35mm format. There are also other camera models that are compatible with 35mm film.
