How to set the parameters of cloudy photography

In fact, the light on cloudy days is much more complicated than that on sunny days. There are many kinds of cloudy days, such as the sun coming out soon. The brightness of bright cloudy days under the sun is EV 13- 12. Typical exposure combinations are F8-5.6+000 and 125 of ISO65438. The color temperature of this weather is generally warmer in autumn and winter. You can manually set the white balance to 5000K, but the brightness can be set. On a standard cloudy day, the whole day is gray but not gloomy. The brightness is EV 12- 1 1, and the typical combination is f 5.6-F4+000 125 of ISO65438. This brightness is ok, but the color temperature should not be too warm. Generally, 5400K is enough. On a cloudy day, the sky is dark and dark clouds are gathering. Sometimes there are small showers. The brightness is about EV 1 1- 10. Typical combinations are F4+000 125 of ISO65438, or F4 of 60 years old. In this case, the color temperature began to turn blue, but fortunately, the general white balance was set to 5800K, and the color performance became worse. These dark parts of the forest in the picture will turn gray. On rainy days, it is very dark, and sometimes it is cloudy or rainy all day. The brightness is about EV 10-9, and the typical combination is F4+000, F4 60 or F4 30. The color temperature is generally blue and white, and the balance should be adjusted to 6000 K. In addition, the color temperature is very different between cloudy days in winter and cloudy days in summer. Cloudy days in winter are generally warmer from late 10 to early March, especially in bright cloudy days or foggy days with weak sunshine. The warmest color temperature is 4500K to 4800K, and the contrast is generally small and gray. Cloudy days in summer are generally neutral or cold, but the atmosphere is transparent and the picture is not gray.
