How much focal length does snow mountain photography need?

Snow mountain shooting is generally far-sighted.

This focal length can also be adjusted automatically.

That is to say, the depth of field is too large, and the conventional setting is above 1 1, because the snow-capped mountains are still reflective.

Aperture above 1 1 will automatically adjust the speed, and ISO is at 100.
