Ask prawns for advice on the brightness of SLR cameras.

1, improve the exposure compensation, this is less used, because this operation is adjusted in the camera and I don't think it can be controlled by PS in the later stage. The adjustment of this parameter is to process the pro-shot photos once through the built-in program of the machine.

2, ISO, improvement can make photos brighter, but at the expense of image quality. If this value is beyond the acceptable range of the camera, there will be noise in the picture, which will reduce the purity and effect of the picture, just like the pockmarked face. Generally, the entry-level SLR ISO needs to be controlled within 800 ~ mid-range 1600, and basically no noise can be seen within 3200 in Quan Huafu.

3, aperture, turning up the aperture can make the photo brighter ~ At the same time, the aperture controls the depth of field. To put it bluntly, it is the degree of background blur. Other parameters remain unchanged. The larger the aperture, the more serious the background needs.

4, shutter speed, slow shutter can make the photo brighter, but many specific conditions restrict the use of too slow shutter, such as banquet photography in the event venue. In order to grasp people's movements, the shutter speed should be higher than100/1s; Too slow shutter speed will cause the picture to shake and produce paste. The normal safe shutter speed is shutter = focal length/1.

5, flash, low power, such as the built-in flash effective distance of 2m, the external effective distance depends on the power, generally 4~ 10m, beyond this distance, the flash used for photography is invalid, within this range, the subject brightness can be significantly higher than the background, achieving the purpose of highlighting the subject and improving the photo brightness.

Extended data:

ISO sensitivity: Generally speaking, the greater the ISO sensitivity, the more sensitive the camera is to light and the shorter the shutter time. However, there will be more noise in the image, which will affect the imaging quality. Therefore, it is generally only necessary to appropriately increase the ISO sensitivity in the case of insufficient light.

Shutter: The time that the shutter remains open. The longer the shutter is open, the more light the camera gets. However, if an object forms a stain in the sports meeting, it can sometimes be used to create gorgeous effects. The faster the object moves, the shorter the shutter time is, the slower the object moves and the longer the shutter time is. For example, when shooting stars, the shutter time is often set to a few minutes or even an hour or two.

Aperture: Aperture controls the aperture on the camera. Generally speaking, the larger the aperture, the greater the light input, and the f value of the aperture = lens focal length/aperture diameter, but the depth of field will become shallow. Using a large aperture can achieve the effect of blurring the background. If you use a small aperture, you can shoot distant objects better.
