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
