Why use high sensitivity? There are three reasons why we must use high ISO.

High-sensitivity photography is a shooting skill that many friends will realize. Aperture, shutter and sensitivity are often adjusted exposure parameters, but the sensitivity is often set in a lower value range when shooting. High ISO is not terrible for many photographers. This is a powerful enemy. So why use high sensitivity? I have to use high ISO for three reasons, but it is not terrible at all.

Why use high sensitivity?

When shooting in 1 low light,

When shooting, you often encounter poor ambient light, such as shooting at night under the stars. Even if the aperture is the largest and the shutter speed is close to the safety shutter, it is impossible to avoid underexposure. At this time, we still insist on ISO 100, which will definitely show a dull color, and no matter how strong it is, it can't be saved later. At this time, it is necessary to improve the sensitivity and sacrifice some image quality appropriately to achieve the desired effect.

2 when shooting with the theme as the main theme and the picture quality as the supplement.

When to use high sensitivity? The best thing is that in some shooting activities or competitions, it is difficult to have multiple shooting opportunities for the shooting theme. If you miss it, you miss it completely. Therefore, it is required to improve the shooting efficiency, and the picture is more important than the picture quality. Then you might as well choose shutter priority mode, high shutter speed, automatic aperture control of the camera and "automatic" sensitivity. At night, ISO may reach 6400, 12800 or even higher.

3 When shooting with a high-speed shutter.

Photography friends all know that the exposure of the shooting picture is determined by aperture, shutter and ISO. In order to meet the needs of high-speed shutter, the aperture must be opened to the maximum, and when it is still insufficient, ISO can only be improved to make the exposure normal. When shooting with telephoto lens, the aperture should not be large and the safety shutter speed should be high. At this time, high-speed shutter is needed, and ISO should be improved.
