What is the shutter adjustment of SLR camera in various situations?

Generally speaking, the camera aperture is in the range of F2 to F22, and the shutter is in the range of 30 seconds to 1/4000.

Aperture and shutter are not a simple distinction between indoor and outdoor. This depends on the lighting environment and shooting content.

For example, when the light is poor, whether indoors or outdoors, it is recommended to use a relatively large aperture to ensure a faster shutter speed and avoid weak imaging; If the light is good, try to use a small aperture to ensure less light transmittance and make the image sharp enough;

Shooting content, if you shoot portraits of scenery and environment, you need a smaller aperture to make the picture contain comprehensive content. If you shoot a still life or a syrup tablet, you need a larger aperture to have a beautiful background blur effect.

Of course, the previous discussion is based on AV files for cameras (that is, aperture priority), and the shutter changes with the change of aperture. The larger the aperture, the faster the shutter, and the smaller the aperture, the slower the shutter. Of course, this is related to the amount of ambient light.

Adjustment skills of aperture and shutter on cloudy days;

1. When taking pictures with a SLR on cloudy days, you can set the sensitivity to 200~400. Don't be too high, or the effect will be lost if the brightness is too high. And when taking pictures, it is recommended to use the aperture first.

In fact, the sensitivity of 100 is enough, because the effect of taking pictures on cloudy days is not as good as that on sunny days. If you want to take good photos, you must find a good weather to take photos. Of course, you can also use PS software later.

2. On the basis of normal photometry, appropriately increase the exposure compensation of 0.3-0.7, and adjust the exposure compensation according to the photo quality, because the exposure compensation varies with different light.

When using the high-speed shutter on cloudy days and at night, we must pay attention to the setting of aperture and ISO to obtain a suitable exposure value. For example, raise ISO to 800 or1600; Or consider using a larger aperture such as F 1.4/F2.8, but pay attention to the depth of field.

3. Setting the appropriate shutter speed is the most critical. Generally speaking: 1/20 seconds, you can get a longer rain belt; 1/60 seconds, can shoot the rain belt that has not yet landed; 1/ 100 seconds, shooting rain bar is short; Shutters with a time of more than11000 seconds can obtain the state of water droplets solidified in the air.

4. The light changes greatly in rainy days. Sometimes the brightness is high in rainy days and low in cloudy days. The exposure between the two can be different by many times. Therefore, when shooting, it is best to use an exposure meter to measure light.
