Fujifilm Astia 100F
Among the three Fujifilm slide films, Astia sat at the quiet end of the saturation scale. Where Velvia pushed greens and reds past what the eye actually saw, Astia kept colors close to the subject. Skin tones in particular landed soft and slightly warm, with a creaminess that made it the default choice for fashion and portrait editorial work in the late 1990s and 2000s.
Slide films in general punish exposure errors, and Astia was no different. Half a stop over and highlights would blow on the transparency; half a stop under and shadows went dark fast. But the latitude sweet spot rewarded careful metering with an almost watercolor quality in skin, fabric, and diffuse window light. Studio portrait photographers who had spent years on Ektachrome 100 Plus often found Astia more forgiving for complexion rendering.
The film ran in 35mm, 120, and 4x5 and 8x10 sheets, including QuickLoad packets for large-format shooters. Medium-format editorial work was where Astia showed its best; the low saturation made flesh tones readable without retouching, which mattered in an era when drum-scanned 120 transparencies were going straight to press. Japanese fashion magazine work leaned on it heavily through the mid-2000s.
Fujifilm discontinued Astia 100F in 2011, part of a broader contraction in the slide film catalog. By that point, digital had taken most of the editorial market and Velvia had captured the residual landscape-and-fine-art segment. Astia, sitting in the middle with its restrained palette, lost its commercial footing. Photographers who still needed a portrait-oriented slide had no direct replacement.
Reciprocity exponent is 1.10. Astia in low light is an awkward proposition anyway, since the narrow latitude of slide film gets harder to manage when exposure times stretch past a second. Zone Light Meter applies the 1.10 exponent automatically: a one-second reading corrects to roughly 1.1 seconds, a four-second reading becomes closer to 4.6. In practice, Astia belonged in daylight studios and on location in good light, not in any situation that needed a tripod and a long count.
How the app handles this stock
- Box speed: ISO 100. Picker exposes pull/push chips so you can shoot it at any speed you want and the meter follows.
- Reciprocity: Above one second the app raises metered time to the power of 1.10.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. Slide decay rates are baked in.
