Polaroid · ISO 800 B&W negative
Polaroid Type 803
Type 803 was Polaroid's 8x10 black and white instant at ISO 800, designed for the Polaroid 81-06 sheet holder, the 81-09 loading tray, and the 81-12 processor that drove the print and negative through the pod reagent under motor or hand crank. The 8x10 format was an entire workflow, not a single product, and it cost real money to enter even when the film was in production.
Polaroid released the 8x10 instant system in 1973. Type 803 sat in the lineup as the fast black and white option, paired with the slower Type 804 at ISO 100 for fine-art print work and Type 809 color at ISO 80 for advertising layouts. Studios used the 803 for portrait sittings where the photographer needed to confirm lighting and pose without waiting for a film lab turnaround.
Tone rendering was wide and gentle. Shadow detail held longer than you would expect at ISO 800, and the highlight roll-off was gradual rather than clipped. Grain in an 8x10 instant print is essentially a non-issue at any normal viewing distance. Compared with the slower Type 804 at ISO 100, the 803 traded a touch of micro-contrast and shadow density for the speed gain. For working portrait studios in available light, the trade was worth it.
Polaroid wound down its instant film operations in 2008 and Type 803 went out of catalog with the rest of the 8x10 line. Surviving stock turns up at large-format auction houses and on eBay at prices that have only climbed since the closure. Boxes with 2009 expiration dates still appear, but expect base fog. The processor pods dry out over the years too, which causes incomplete development streaks even when the emulsion itself is fine.
Format is 8x10 sheet film, fifteen sheets per box, processor required. Long discontinued.
Reciprocity exponent is 1.0. Zone Light Meter applies the correction past one second. With a 1.0 exponent the metered time equals the shot time, which made the 803 well-behaved for long exposures in dim studio scenes. Bracket aggressively on any freezer-stock you find today.
How the app handles this stock
- Box speed: ISO 800. Picker exposes pull/push chips so you can shoot it at any speed you want and the meter follows.
- Reciprocity: No reciprocity correction needed; metered time is the shot time.
- 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.
