Polaroid · ISO 640 Color negative
Polaroid Go Color
Polaroid Go arrived in April 2021 as the smallest analog instant format on the market, a miniaturized version of the classic square frame. The cartridge holds eight prints. Each measures 66.6 by 53.9 mm with a square image area of 47 by 46 mm, putting it below Instax Mini in image size and well below the i-Type and 600 formats Polaroid has made since the SX-70 era. ISO is 640, daylight balanced, development around ten to fifteen minutes.
The Go format is also incompatible with every other Polaroid camera. The body and cartridge form a closed system, which means a roll of Go film fits only the Go camera. That decision frustrated some buyers and made commercial sense: the camera is small enough to clip to a backpack strap, and you cannot put i-Type chemistry into something the size of a credit card.
Image quality is what you would expect from a tiny instant frame. Colors lean warm and slightly desaturated, with the soft contrast curve Polaroid has been refining since the Impossible rebuild. Compared with Polaroid 600 Color or i-Type, Go renders a touch flatter because the print is so small that high-contrast scenes lose midtone definition before they finish developing. Treat it as a snapshot format and it works.
ISO 640 is shared across most current Polaroid stocks, the speed that lets a fixed-aperture body handle outdoor sun, indoor flash, and evening light without a diaphragm. Indoors without flash the Go is past its useful range and prints come back dim.
Format is the Go cartridge, eight exposures, color. There is no Go B&W version; the line stays color only, including a Black Frame edition that is still color film inside black borders. Production continues; this is one of the few instant formats you can still buy fresh in 2026.
Reciprocity exponent is 1.0. Zone Light Meter applies the calculation past one second, but the Go camera offers no control over shutter time, so reciprocity is theoretical here. A metered 2-second exposure stays at roughly 2 seconds at the film. The camera handles all timing internally.
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.
