The efke 100 is a black and white film. The formula comes from the ADOX KB film from the 1950s. It was produced by Fotokemika in Croatia, which ceased production, and thus this film, in 2012.
The black and white film was available in the following formats 35mm (efke KB 100), 120 (efke R 100), 127 and as a sheet film (efke PL 100 M).
The efke 100 has a sensitivity of ISO 100 and has a single-layer emulsion with a high content of silver.
It is developed in a black-and-white developer, such as Rodinal or Kodak D-76, XTOL or HC-110. During development, special attention should be paid to the wet emulsion, as it is very sensitive. It is advisable not to have it developed in a large laboratory.
Besides the ISO 100 film, there was also a version with ISO 25 and ISO 50.
As an alternative to the efke 100, you can go for the Adox CHS 100 II.
