Come for emergency help, sunny day. How many shutters should I use? How much is the aperture?

16 sunny, 8 cloudy. 1 1 cloudy day, dusk on the 4th. Clouds cover 5.6, and it will snow in rainy days.

Set the shutter to the value closest to your ISO, and determine the aperture according to sunny day (the shadow on the ground is very clear) F 16, cloudy day (the shadow is blurred and the color is very light) F8, cloudy day (the edge of the shadow on the ground is blurred) F 1 1, and cloudy day (the shadow on the ground is blurred) F5.6, that is, if Your shutter is 65438+ and the aperture is F 16, but if your aperture is set to 2.8 (the aperture is increased by 5 steps), the corresponding shutter will be reduced by 5 steps and set to 1/4000, and so on. However, due to the lighting conditions when shooting, the required photo style, and specific problems are analyzed.
