ATTENTION: We have discovered a speed issue with this emulsion. We have brought this to the attention of ILFORD and they have yet addressed the issue. We do not know if this problem is permanent. The Issue is "all-use" both negative & dr5 processing. Normal iso has jumped about 3/4s of a stop. This film has the same great look but we can not be certain of its future speed.
NOTE: dr5 processed DEV2 has been proven to be impervious to environmental damage. DEV2 is "completely archival"
SFX has a very slight-hazy-METALIC look.
In developer 2-sepia SFX produces a stunning
metallic sepia/selenium tone. This is a very unique film type. In dr5 the normal iso is 320iso. SFX - DMAX is low because of its infrared qualities, around 3.00, once you get the particulars of exposing this film the image quality is priceless.
It is possible to obtain some IR effects with SFX using the darkest IR filters. Exposure will depend on the scene and it is suggested you test using filtration. Use SFX as a normal film, without filtration in most cases. With filters, use the base iso and apply the filter factor.
ILFORD SFX - Ei: 100~640
DEV-2 NORMAL dr5 ISO: 320
