Fujifilm Nexia 800 (APS)

Nexia 800 was the fastest film Fujifilm ever made for the doomed Advanced Photo System format. Released in the early 2000s as the world's first ISO 800 APS emulsion, it used Fuji's 4th Color Layer Technology, the same fourth cyan-sensitive coupler that later went into the professional NPZ 800 and NPH 400 stocks in 2002. In a format built for point-and-shoot tourists, this was overkill in the best sense.

The IX240 cartridge wraps 24mm-wide film behind a transparent magnetic strip, and the camera writes exposure data, date, and aspect-ratio choice (C, H, or P) per frame. Nexia 800 was the stock you loaded for a flash-free night shot at the kid's birthday party without the camera going stupid. Grain at box speed is tight for an ISO 800 consumer film, cleaner than Kodak Advantix 800 of the same period and less green-shifted than the Konica Centuria 800 sibling.

Color is honest rather than punchy. Skin reads warm but not orange, mixed indoor light handles cleanly in the print, and the highlight latitude runs the usual three stops over that consumer C-41 always offered. Underexposure is where it falls apart: a stop down and shadows go muddy red, the way old fast films tended to.

Compared with 35mm Superia 800 of the same era, the APS variant is softer because the frame is smaller (30.2 x 16.7mm at maximum H crop). Print bigger than 6x8 and the grain becomes the texture.

Processing is the hard part now. Fujifilm killed APS in July 2011 and most minilabs scrapped their IX240 attachments years before that. A small number of US labs still handle it and turnaround runs slow. Expired rolls go for absurd prices given the lab tax that follows.

Reciprocity exponent is 1.2. Zone Light Meter applies the correction past one second. A 10-second meter reading climbs to about 16 seconds at the negative; a metered 30-second exposure becomes about 60 seconds in the camera. For a film built around flash and short hand-held exposures, that math will almost never come up.
