So you’re setting up for that first shot, better get those camera settings right! At first it’s pretty confusing holding ISO, aperture and shutter speeds in your mind as well as angles and timing, let alone what they all mean, but with a little bit of practise it starts feeling pretty natural quite quickly. In the end it’s all down to personal preference, but ISO is normally the first thing you’d set on your camera.
This is a term that comes from film photography, where the ISO number on a roll of film tells you how quickly it reacts to light when you expose it by opening the shutter. Low numbers develop slowly, high numbers quickly, but with more ‘image noise’ – random speckles of colour in the picture. Transferred to DLSR photo and videography, it dictates the sensitivity of the sensor. It’s normally best to keep it as low as possible to avoid a grainy image, but you may need to compromise in low light.
