Efke films are manufactured using classic emulsions with very
high silver content. This results in a large grayscale reproduction. The
Efke 25, 50 and 100 films are made using the ADOX formulas that were
first introduced back in the late 1940s.
Unlike modern flat
crystal films, which are very unforgiving to use, these films allow
beginners to produce quality images. The nature of the film also easily
allows large, grain free, enlargements to be made from negatives.
Features
- Traditional Black and White Film
- 120 Medium Format
- Do NOT over-expose Efke Emulsions! This film is not recommended for push processing.
- Treat the wet emulsion with extreme care. We recommend the use of hardener in the stop bath or fixer.
- Never
use a stop-bath with a higher concentration than 2% -- in fact, we
recommend the use of plain water in place of a stop bath.
- Efke roll films are coated on a polyester base (100 microns plus coating)
If exposed to film's regular speed of ISO 50, the following developing times apply:
Kodak D76/ID-11 = 7 Minutes
If
ISO 50 film is exposed to ISO 100 for increased speed and optimum
differentiation of highlights, the following developing times apply:
Kodak D76/ID-11 = 9-10 Minutes
