EFKE 25 roll & Lrg- Ei: 12~25 iso
DEV-2 NORMAL dr5 ISO: 25
The efke25 produces quality in dr5. Efke-25 is the sharpest conventional B&W film still available, especially in dr5. Efke films are silver rich, with an old-fashion image quality. All the EFKE films are single-layer emulsions.
Efke-25: Unlike reported issues with negative development, efke-25's tonal range is greatly improved in dr5. Contrast is added gradually past 25iso. If you have to go above 25iso [dr5], shoot this film in a low dynamic-scene. If you have to shoot a high-contrast scene with this film, it is best to choose a low iso [use a tripod]. This film tends to change for the worse with age unless it has been kept in deep freeze for storage. [never keep opened rolls in cold-store]. From processing this film over the years, we find that E25 can have exposure challenges in some light conditions. It might be best to test this film, then make adjustments for your conditions.
A yellow/brown in developer 2-sepia with the same contrast range as the neutral image. The dmax has a modest 3.10 on average. efke & ADOX branded films are the same. They both come from the same plant.
NOTE: dr5 processed DEV2 has been proven to be impervious to environmental damage. DEV2 is "completely archival"
NOTE: The efke120-film will fog easily. We advise special care. Treat it as you would any high speed film. Use a container or foil to cover the 120 rolls after it has been shot.
ALSO NOTE: ALL EFKE/ADOX films vary from emulsion to emulsion. Though we like these films best for dr5, & test them when possible, we find the emulsion-changes can vary as much as 20%. We would highly suggest if you want to use EFKE film - NEG or dr5, test a 'roll/sheets' of purchased stock [10~50 rolls] before doing serious shooting. Testing your stock, old or new, will insure correct exposure.
