Kodak Aerocolor IV 2460
Known/rumored respoolings: Popho Luminar 100, Flic Film Elektra 100, SantaColor 100, and Film Washi X (per popho.ca, bhphotovideo.com, and analog.cafe).
Observations: The actual speed of this film stock can seem a little ambiguous. Kodak’s own data sheet specifies a film speed of ASA 125 specifically for aerial photograhy, the intended application for this film. But Kodak is also quick to point out that this usage differs substantially from more conventional photography. That same data sheet adds that the aerial film speed is rounded to the nearest 1/3-stop, which presumably means that, for conventional photography, its ASA rating corresponds with the box speed of Popho Luminar 100, Flic Film Elektra 100, and SantaColor 100. When I shot this film stock, I did so at that slower speed. In general, this film stock has a nice vintage look with muted, low-saturation color and pleasingly fine grain. This is perhaps the most interesting slow-speed color film stock I’ve ever shot.
