When taking pictures, your face with your back to the sun will be very dark. How to adjust the camera?

Looks like the landlord used automatic exposure.

But computers are not human brains after all.

Sometimes you want to shoot an object A, but there is a light source B (bright, of course) behind this object A..

At this time, only you know that you want to shoot A, not B, but AB appears in the picture at the same time, so the computer doesn't know which one you want to shoot. Because the brightness of A and B are different, the exposure must be different.

At this point, the computer control in the camera may give the average light measurement. At this time, if the photo is exposed, take the middle value of AB. You want to shoot A, but the picture is underexposed and not ideal for A (overexposed for B).

Some cameras are more user-friendly and have a little metering. When shooting, the point is aimed at A, and the computer will automatically measure light according to the brightness of A, which makes up for the lack of average measurement.

Solution: 1 spot light to measure a.

2 flashlights

3 Manual exposure adjustment, the exposure is based on the value measured by A.
