This phenomenon is a typical large light ratio problem, because the brightness difference between the sky and the ground is several levels, so it is impossible to expose the sky and the ground correctly at the same time only by adjusting the parameters without using some special methods. Generally speaking, there are two ways to solve the problem of large light ratio:

.

1 Use a gradient filter.

The prime camera is equipped with a tripod, and the aperture is modulated first. The spot metering mode is used to meter the sky and the ground respectively, and the parameter values of the two are recorded.

Then set the camera to m, use the parameters of ground photometry just now and fix it;

Through the photometric parameters of the two just now, the difference of exposure series between them is calculated;

Select the gradient filter of the corresponding gear and put it in front of the camera to shoot, so that the sky and the ground can be exposed correctly at the same time.

You can look up some landscape photos taken with gradient filters on the Internet.

.

2 using HDR synthesis method.

The camera is also mounted on a tripod to keep the composition unchanged.

Measure the sky, the ground and the middle with spot metering and shoot;

You can get multiple photos with the same composition but different exposures;

Just use the software on your computer to HDR these photos.

The advantage of HDR is that it saves money on filters, but sometimes it is beautiful at first glance because it violates the optical laws of human vision, and sometimes it looks a bit fake after a long time.
