How did Canon 5D2 take such a photo? The background is very dark, the exposure is so good and the definition is so high.

With a telephoto and a large aperture

3. Choose a place where the background light is relatively small and the character light is relatively large (visually, this character reduces the background exposure or brightens the character exposure later).

4. Add serious dark corners in the later stage.

PS: This picture is very ordinary, nothing special. Anyone who can shoot can shoot. The dark corner, especially the lower left corner, is really terrible.

I think: teachers are the key to learning photography. Without teachers, other people's works become the best teachers. Maybe you don't have enough skills to take such photos at present, but if you don't even have excellent aesthetic vision, you can't judge whether the teacher and the picture are excellent or not, and it's easier to go astray. thank you
