Please give us your advice: 1. How many apertures and shutters should be used in summer, sunny afternoon and cloudless temperature of 37? 2. The conditions are the same as above. How much should it cost to shoot the sunset? Give you a sunshine 16 rule:

Sixteen sunny days and eight cloudy days

Cloudy, eleven days and four nights.

Cloud cover exceeds 5.6.

Rain, snow and sunset.

Indoor court for two seconds

Shutters on the living room stage 8

In outdoor sunlight, if the aperture is f/ 16, the shutter speed should be the reciprocal of the international sensitivity index of the film used. For example, in outdoor sunlight, the aperture is f/ 16 and the film sensitivity is EI 100, then the shutter should be1100 second.
