WebJan 24, 2024 · This is easy in good lighting conditions as your camera doesn't need a very high ISO setting in order to capture the image. So, if there's plenty of light in the scene, you can use a setting such as ISO 100 or 200. When shooting in trickier conditions, you may need to raise this ISO, perhaps to ISO 3200 or 640000 – or maybe even higher. WebExposure Value (EV) is desribed as: where N is the relative aperture, t the exposure time (shutter speed) and S the ISO speed. An aperture N=f/1.0, a shutter speed of t=1s and an ISO speed of S=100 corresponds to EV=0. An EV of +1 means half the light, and EV of -1 means double the light of EV=0 will be exposed to the recording medium.

WebThis is based on the Zone System, which goes from pure white to pure black. 18% grey is exactly midway between the two. This is what is known as Exposure Value.
