Polaroid 600 Color

Color negative ISO 640 Discontinued Instant saturated · unpredictable · 600-series

The company that makes this film today is not the company Edwin Land built. Polaroid went bankrupt in 2001 and again in 2008. The Impossible Project, started by ex-Polaroid factory manager Andre Bosman and Austrian film dealer Florian Kaps with a small team of former Wolfen and Enschede film specialists, bought the last factory in Enschede, Netherlands in 2008 and spent years reformulating the chemistry from scratch. They rebranded as Polaroid Originals in 2017 and then just Polaroid in 2020. The cameras are original old stock or new reissues; the film is entirely new.

For 600-series cameras like the OneStep Express, the Sun 600, and the Impulse, the ISO 640 emulsion is the current color option. Colors run warm and slightly saturated. Blues shift toward teal in shade; skin tones in tungsten light go orange fast. The unpredictability is not a defect to complain about; it is what people buying instant film in 2024 are actually paying for. Two shots of the same scene under the same light can come out slightly different, because the coating tolerances are tighter than original Polaroid but still nowhere near conventional film.

Development takes about 15 minutes at room temperature. The official advice is to shield the print from light during the first minute after ejection; old habit from the Impossible days when the chemistry was genuinely fragile. Current emulsion is more tolerant, but cold weather still kills it. Below 55F the pod chemistry slows down and you get pale, washed-out prints. Tuck the camera inside your coat between shots in winter.

Reciprocity is listed at an exponent of 1.0, meaning the emulsion holds roughly linear response past one second. In practice you almost never use this in long-exposure work because the built-in flash circuit and auto-exposure system on 600 cameras are not designed for tripod shots. If you do force a long exposure, Zone Light Meter applies the correction past one second. The real constraint is not reciprocity; it is the fixed development cycle and the pod count of eight shots per pack.

How the app handles this stock

  • Box speed: ISO 640. 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. Color negative decay rates are baked in.
