Which grade is the best for taking pictures in the sun with a SLR camera?

Use "aperture priority" files, that is, A files (Nikon) or Av files (Canon).

Not only in the case of direct sunlight, but also unless shooting fast-moving objects, it is generally recommended to use a file.

In the case of direct sunlight, it is necessary to adjust EV (Exposure Compensation) according to the picture content. Generally, press the button with "Yin and Yang in the box+-"on the camera, and then adjust the dial.

The landlord didn't mention whether it was a person or a scene, but simply classified and discussed it:

1, character

If you don't wear a hat, please try to make people face the sun, otherwise it will be difficult to deal with the strong shadow on your face.

If you wear a hat or cover the sun with your hands, please blow it slightly to ensure that the face covered by the shadow of the hat is not too dark.

2. Scenery

According to the proportion of direct sunlight content in the picture, choose to adjust EV. For example, shooting a white wall in direct sunlight requires a lot of EV; Shooting a black sports car in direct sunlight requires lowering the EV.

Remember the formula of "white plus black minus"? The more white things in the picture, the more you want to increase EV. The more black content, the less.

Photography is a complex science. Specific analysis of specific problems can only tell you some basic knowledge for you to use flexibly.
