What knowledge do you need to know about taking group photos?

1. Flash synchronization speed

Flash synchronization means that the light emitted by the electronic flash is synchronized with the operation of the camera shutter, so that the light from the flash will be recorded by the camera. That is, at the moment when the flash fires, the shutter should be fully open to ensure that the picture is evenly exposed. Otherwise, there will be some areas that are not sensitive to light, that is, partial blackness will be seen in the picture.

2. Shooting in M ??manual exposure mode

M manual exposure mode is mostly used for shooting in the studio. In manual exposure mode, photographers can set aperture and shutter speed as needed. In order to ensure a clear picture and minimize the impact of hand shake on the picture, the shutter speed of the camera is mostly set to the fastest flash sync speed of a digital SLR camera, and the aperture is adjusted according to the value measured by the light meter. , generally set to around f/8, f/11. This aperture setting can bring excellent image quality and a large enough depth of field to ensure a clear picture.

3. Light meter metering

In order to make the exposure more accurate, we can also use a light meter to measure light for auxiliary shooting. But now the function of digital cameras to shoot and see has weakened the role of light meters.
