While 35mm and 120 film will need to be developed after you’ve shot it (more on that below), the advantage of instant film is that it pops out of the camera straight away. When most people think of instant film, they think of Polaroid cameras, and since the brand’s regeneration there are loads of great Polaroid cameras and film types to choose from. However, Fujifilm Instax format is also popular – its prints are smaller and less detailed, but also more affordable and faster to develop.
