Efke 2.25 x 3.25" PL 25M Black and White ISO 25 Negative Film is a fine grain, extremely sharp film that is characterized by a very high silver content. Prints displaying an excellent gray scale tonality are produced using traditional black and white developers. Efke films are made using ADOX formulas (for high resolution) that were first introduced back in the 1950s.
Efke products are true to their rated speed. They allow both amateurs and professionals to produce high-quality prints. As a result of the fine resolution of this film, large, grain free, enlargements can be made from the negatives.
Made in Croatia
Efke roll films are coated on a acetate base (130 microns plus coating)

Treat the wet emulsion with extreme care; Efke recommends the use of hardener in the stop bath or fixer; never use a stop-bath with a higher concentration than 2% -- in fact, Efke recommends the use of plain water in place of a stop bath
