Films for the Naigai SRF
The Naigai SRF needs 35mm film. Films of this format are still easily available today and are still being developed. For colour photography there is the Fujifilm Superia 400*. One possibility for black and white images is the AgfaPhoto APX 400*.
The development of photo films is still possible without any problems nowadays, especially 35mm films are still developed by many photo labs. However, the prices for this service can vary greatly depending on the type and scope of the service. The most common process for developing colour film is the C-41 process, which is offered by almost all photo labs and follows a strict standard.
Developing black and white film, on the other hand, requires a special black and white developer, the results of which can vary greatly depending on the choice of developer. Professional photo labs also offer black and white development, but the best results are achieved by developing the film yourself and having full control. Online, you can find the necessary accessories for a home lab and also suitable developing chemicals for the film. Popular developers are Rodinal, XTOL, ID-11 or D-76, while Adox, Rollei or Foma are smaller suppliers that also offer suitable chemistry.
