Lightmeter is a film camera that lives on your iPhone. Photos get real grain, glow and film colour, built from the raw image, not a filter. New: the LM-35 AF disposable camera. No screen to check, just a roll of film and an hour’s wait for your photos to come back from the lab. It’s also a light meter for real film cameras. Free to download, no sign-up, and your photos never leave your phone.
