Lucky SHD 100
Lucky SHD 100 is what happens when a Chinese state-era film factory finds a second life serving hobbyists. Lucky Film Corporation in Baoding shut down most consumer production around 2012 when digital killed demand. They quietly relaunched SHD 100 in 2017 on a revised base at roughly 5 euros a roll, and rebuilt small overseas distribution through Reflx Lab and a handful of European sellers.
The defining feature is what is missing. There is no anti-halation layer on the back of the emulsion, the way Fomapan 100 has one and Kentmere 100 has one. Point light sources bloom around the edges in a way that reads as either dreamy or sloppy depending on the frame. Backlit subjects glow. Streetlamps spread. If you want clean technical separation, this is the wrong film. For a soft 1970s look out of a fresh roll, it is among the cheapest paths to it.
Grain is fine for the price tier and the gray values are pleasant in the mid-tones. The film cannot match T-Max 100 or Delta 100 for resolution, and it loses to FP4+ on shadow rendering, but at half the cost per roll the comparison is not really the point. Rate at box speed in flat light. In contrasty sun, pull a third of a stop and the halation gets more controllable.
Develop in D-76 1:1 for around 12 and a half minutes at 20C. Rodinal 1:25 finishes in six and a half. The Luckyfilm-branded developer on Chinese sites works but is harder to source outside Asia, so D-76 or ID-11 is the practical default.
Available in 35mm 36-exposure cassettes and 120 from Lucky directly, and through Reflx Lab internationally. No sheet format. Bulk loading is possible if you can find the 100-foot tins.
Reciprocity exponent is 1.31. Zone Light Meter applies the correction past one second. A metered 30-second exposure becomes about 90 seconds at the negative. The lack of an anti-halation layer matters more for long exposures than you might expect, since any bright light source in frame blooms more aggressively the longer the shutter stays open. Frame accordingly.
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 1.31.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. B&W negative decay rates are baked in.
