Not even Hollywood can escape maths! If you’re a cinematographer or camera operator, you’ll definitely be needing maths for the day to day technical working of a video camera. Maths is used to choose the appropriate aperture speeds (how much light passes through the lense), the focal length of lenses to capture a scene, and to decide on the best camera angles for a shot. This will be really testing your geometry skills. And if you need to calculate angle of view to focal length (say you’re trying to film something far away and need to choose the right lens) then you’ll probably be using trigonometry to work it out.
Cinematographers will also need to calculate things like speed of light, exposure and depth of field. In fact, cinematographers need to work out complex calculations a lot of the time in order to get those beautiful shots we all love.
