Toying with Creativity
Plastic cameras afford the freedom to be creative without having an attachment to the outcome.
I have a variety of cameras I use when I'm making photographs and some of my favorites are made of plastic like the Holga, Fuji Instax 200 and the Lomography Fisheye ll. The Holga uses 120 film the Fuji uses instant film and the Fisheye ll uses 35mm film.
I use these very unsophisticated cameras for a number of reasons. There's no worrying about white point, exposure compensation or even focusing. It's really quite liberating to just make pictures. I have an idea of what's on the film but it's only confirmed when I get the prints back from the lab.
