Kodak Double-X 7222

7222 is the 16mm version of the Double-X emulsion that runs as 5222 through 35mm cinema cameras. Kodak introduced the stock in 1959 and has kept it in production ever since, making it one of the longest continuously manufactured film products of any kind. The chemistry has been tweaked, but the look is stable enough across decades that footage shot on 7222 in 1963 cuts together with footage shot last week.

Nominal speed is 250 in daylight, 200 under tungsten. The grain is medium-coarse and structured in the way that reads as filmic rather than digital, which is the entire reason still shooters have started buying it. Contrast runs hotter than HP5+ or Tri-X. Shadows drop faster, highlights compress earlier, and the mid-tone scale has the punch that characterized news and documentary cinema through the sixties.

Janusz Kaminski shot most of Schindler's List on the 35mm 5222 in 1993, with Plus-X 5231 covering the slower scenes. The 16mm 7222 covers an even wider catalog: PBS documentaries, music videos, and student film work where the cost gap between 16 and 35 actually matters. Cine cameras run it in D-96, the motion-picture B&W developer, while still photographers hand-rolling 16mm cartridges or shooting a Minolta-16 typically use D-96 or D-76 1:1.

There is no rem-jet on 7222. It carries only a conventional anti-halation layer that develops out in standard B&W chemistry, so you can load it directly into a tank with D-96 or D-76 1:1 once you have wound it onto a reel.

Reciprocity exponent is 1.31. Zone Light Meter applies the correction past one second. A metered reading of 90 seconds becomes about two and a half minutes at the negative. Long exposures on Double-X have a deep-shadow-block character the reciprocity curve only deepens. For long night work, bracket. For everything else, this is one of the more honest looks you can put on a small format.
