“The most powerful weapon in the world, as far as I’m concerned, is the camera.” — Paul Watson
The purpose of camera tests are to put a camera system through it’s paces to expose (if you pardon the film pun!) its strengths and weaknesses, thus creating a library of footage that will serve as a reference for your production.
The principal of camera testing obviously originates with testing different film stocks – but like each film emulsion, each digital sensor is different. With so many new digital cameras available on the market it’s difficult to know the pros and cons of each… and whether your preferred camera fits your preferred shooting style. You don’t want to just pick a camera and then hope it’ll work nicely in low light if you’re shooting night scenes. Or hope that it’ll be great at handling highlights if you’re filming in the midday sun.
Obviously most indie filmmakers don’t have the luxury of choosing from a range of cameras (or film stocks!), but it’s still vital that you test the camera you’re planning to use for your shoot – familiarising yourself with its optimum operating settings allows you to showcase the camera’s strengths while hiding its weaknesses — and in turn making your cinematography appear more considered and crafted.
Here’s a really cool video from KODAK that features an elaborate camera test designed to showcase improvements in the VISION3 Color Neg Film 5219/7219. Clearly you don’t have to go to such lengths but it’s a great template to help you design your own camera tests.
