Kodak Advantix 100 (APS)

Advantix 100 was the slow option in the Kodak APS lineup that launched the Advanced Photo System in February 1996. The pitch from Kodak, Fuji, Canon, Nikon, and Minolta was that 35mm needed a smarter replacement: drop-in cartridge loading, magnetic data exchange per frame, three aspect ratios chosen at capture. The negative sits at 16.7mm by 30.2mm in HDTV format, about 40 percent smaller in area than 35mm. The 100 speed was aimed at outdoor family use where the small frame prints cleanest at 4x6.

The emulsion carried T-Grain technology from the same generation Kodak was using in Royal Gold 100, which kept grain tight given the format penalty. In 4x6 prints, Advantix 100 holds up well. The gap to 35mm Gold 100 only opens once you push past 5x7. Compared with Fujicolor Nexia 100, the competing APS option, Advantix 100 is slightly warmer in skin tones and slightly less saturated in greens. That is the Kodak versus Fuji distinction that persisted across formats.

Cartridges came in 15, 25, and 40 exposure lengths, with the 25 being by far the most common secondhand find. The 40-exposure roll showed up more often in travel and family bundles than on shelves of individual cartridges. The cartridge itself is the IX240 design: a 39mm plastic shell with visual indicators for unexposed, partially exposed, fully exposed, and processed states. Mid-roll change was supported on premium cameras and almost never used.

Kodak discontinued Advantix in 2011 along with the rest of APS. Freezer cartridges from the early 2000s turn up on eBay and usually still work because the IX240 shells seal well against humidity. Use it as a daylight family film. Home flatbed scanning loses the magnetic track that tells the lab how to print each frame, so a lab with a working Noritsu APS module is the cleanest path.

Reciprocity exponent is 1.2. Zone Light Meter applies the correction past one second. A metered 12-second exposure becomes about 20 seconds at the negative. That matters more than it sounds because APS point-and-shoots had night modes that pushed shutters into that range.
