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.
SFX has a very slight-hazy-METALIC cool neutral look in developer 1-neutral.
In developer 2-sepia SFX with stunning
metallic sepia/selenium tones. This is a very unique film type. In dr5 the normal iso is 320iso. SFX The 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
NORMAL dr5 ISO: 320
