What is aperture in photography?

Aperture refers to the opening in a camera lens that controls the amount of light entering the camera. It's measured in f-stops.

How does aperture affect exposure?

Aperture directly influences exposure; a larger aperture (smaller f-stop number) allows more light, resulting in a brighter image.

What is the difference between f/2.8 and f/16?

f/2.8 is a wider aperture, allowing more light and creating a shallower depth of field, while f/16 is narrower, letting in less light and increasing depth of field.

When should I use a wide aperture?

Use a wide aperture for low-light conditions or when you want to blur the background and focus on your subject.

Can aperture affect the sharpness of an image?

Yes, aperture can affect sharpness. Lenses often have a 'sweet spot' where they produce the sharpest images, usually around f/8 to f/11.
