Kodak Double-X (5222)

Kodak Double-X (5222) is the one emulsion I have pulled and pushed the most and then developed in Diafine. It is a truly superb film, with very wide latitude. It can be comparably fine grained, even at its ordinary sensitivity, which is around ISO 400, and really grainy when pushed a stop. It is best to buy it on 400-foot bulk roll cans directly from Kodak. Avoid the re-branded exceptionally overpriced Cinestill variety.
