How much is the adjustment of aperture and shutter in cloudy days?

The setting parameters of cloudy SLR are as follows:

1. When taking pictures with a SLR on cloudy days, you can set the sensitivity to 200~400. Not too high, or too high and too bright. The effect is gone. And when taking pictures, it is recommended to use the aperture first. In fact, the sensitivity of 100 is enough, but choose to take pictures when the weather is good! 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 different light exposure compensation is different. 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.

5. In order to match the gloomy atmosphere, you can adjust the tones of blue and gray. You can adjust the white balance in front of the camera, which will make the photo blue, about 6500k, and then subtract 2/3 to 1EV to make the photo look darker. Note that it is not the white balance on a cloudy day, because the white balance on a cloudy day will make the photo yellow to balance the blue on a cloudy day. If the camera doesn't have K key, you can choose white balance of tungsten lamp. If you shoot RAW files, these can be adjusted in post-production. You can also reduce the saturation and even adjust it to black and white, which looks good.
