Fujifilm · ISO 400 Color negative
Fujifilm Industrial 400
Fujicolor Industrial 400 was the faster member of Fuji's Japan-only B2B color negative line, sitting on the same dealer shelves as Industrial 100 in plain packaging that translated to "recording film for business." The film never had a consumer push outside Japan. Most photographers in the rest of the world found out about it through importers in the mid-2010s. Bar codes on the developed negatives matched Fujicolor Superia X-TRA 400 closely enough that the working consensus is that Industrial 400 was the same coating at a lower B2B price.
Whether the emulsion was exactly identical to Superia 400 is something Fuji never confirmed in print. Side-by-side test rolls scan close enough that the differences fall within run-to-run variation. The character is the standard Fuji 400 signature from that era. Cool greens, cyan-leaning skies, balanced reds, skin tones that drift cool rather than warm. Compared with Kodak Gold 400 of the same period, Industrial 400 holds blue better and skies look less like memory and more like a meter reading. Compared with Portra 400 it gives up two stops of usable latitude for half the price.
Grain at ISO 400 is moderate, not particularly fine for a current-generation Fuji emulsion. Push to 800 works at the cost of muddy shadows. One stop is the practical ceiling.
Fuji discontinued the Industrial line in 2020. 36-exposure rolls turned up in brick packs through Japanese resellers. No 120 version. Freezer stock from before 2020 still circulates at prices that have crept up from five dollars a roll to twenty or twenty-five.
Use it the way Fuji shooters used Superia X-TRA. Daylight family, indoor events, evening street where the latitude does most of the lifting. Rating it at 320 in shade gives cleaner shadows. Standard C-41 in any lab.
Reciprocity exponent is 1.20. Zone Light Meter applies the correction past one second. A metered 8-second exposure becomes around 12 seconds at the negative, which matches the indoor flash-off and dim-restaurant shots this stock was used for.
How the app handles this stock
- Box speed: ISO 400. 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 1.20.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. Color negative decay rates are baked in.
