Efke KB100 Black and White 135mm film is manufactured using classic emulsions with very high silver content. This results in a large exposure latitude and superior grayscale reproduction. The Efke 25, 50 and 100 films are made using the ADOX formulas that were first introduced back in the 1950s.
Efke products are true to their rated speed. 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.

Comments about Efke KB100 Black and White 135-36 Size Film:
Excellent results with this film, even though I likely underdeveloped with D-76; that does attest to its great exposure latitude, that's for sure. Grain is fantastically small yet gives a classic feel. This is by no means a beginner film though, buyers should be cautioned. Unlike Ilford and Kodak films most people are familiar with, the emulsion on this guy is not only thin but super delicate. Cleaning them with the finger method will probably damage them. This aside, with careful handling these are absolutely superb.

This is an amazing film with a look all it's own. The texutres are rich and deep. A true treat to use.
Comments about Efke KB100 Black and White 135-36 Size Film:
nice smooth pictures. I don't like grain (or too much grain) in my photos so this film was great. But it wasn't flat either (it had a little bit of contrast). Obviously a lot has to do with the developer and printer but I was very happy with the results from this film.
