As many of you most likely already know, Kodak Panchromatic Separation Film 2238 (ESTAR Base) is a black-and-white film and was originally intended for making archival black-and-white separation positives and special effects from color negative and Black-and-White originals. But utilization in standard 35mm cameras has yielded wonderful results from shooting at ISO 6 on up to 50m, but shooting at 25 has become a favorite around here. We are doing our usual and offering it in 36 Exposure and 100 foot rolls. Sometimes referred to as the Poor Man's Tech-Pan.
Here are some shining examples of 2238 shot through a camera from the Flickr Site
