Which scene requires the highest exposure and light direction?

Scenery is a kind of control and creation of the picture content. Refers to the field of vision formed by the distance between the lens and the object being photographed.

Be sure to shoot in bright light, so there is less "snow noise" and the color returns to normal. Three elements of exposure: aperture, shutter and ISO (these three factors determine the exposure, or, if any two parameters are known, the other can be uniquely determined). In fact, it is a ratio. Aperture = lens focal length/aperture. (So, most of the logo on the old lens are 1: 1. 4) That is to say, taking the header as an example, it is 50mmf2, and the actual aperture is 25 mm at this time.
