Because the demise of Kodak B&W Plus-X emulsion (31), shooting B&W film outside is challenging. 5222/7222 is the only Kodak B&W camera stock. Outside it is has an exposure index of 250. In the test described below the daylight was metered at 8,000 foot-candles. At 24fps this would require a f stop setting of around f64, or a very dark ND filter. Most lenses are sharpest at about 2 stops from open, this is impossible for 22 outside without using an ND15 or ND18 to get f5.6 or below. The contrast of direct sunlight & shadows is a struggle for any photographic medium. 5234 B&W duplicate negative is an intermediate film and is quite slow. 34 has a gamma less than one making it suitable to shoot and print. It is also panchromatic and available in acetate 16mm or 35mm. For the test it was rated at EI 6 for D96 processing.

The results of the test were the following: The grain structure and response of 5234 is clearly finer. It is a very smooth image and out performs the 5222 outside. It is availible from Kodak in both 35mm and 16mm. We will do a test of 16mm soon, I am sure the diffrence will be even more dramatic. While this stock would be hard to shoot indoors, outside it is beautiful. If processed D97 is would have an exposure index of about 18 allowing for less direct sunlight. It is also cheaper 5222 $0.444 vs 5234 $0.391 per foot.
