What is the best aperture for depth of field?

What is the best aperture for achieving a shallow depth of field?

For a shallow depth of field, you typically want to use a wide aperture, such as f/1.4 or f/2.8.

And what about for a deep depth of field?

For a deep depth of field, a smaller aperture like f/8 or f/11 is ideal, as it keeps more of the scene in focus.

How does aperture affect exposure?

Aperture controls the amount of light entering the lens; a wider aperture lets in more light, while a smaller one lets in less.

Can you give me examples of when to use different apertures?

Sure! Use wide apertures for portraits to blur backgrounds, and smaller apertures for landscapes to keep everything sharp.
