Tips

usage

Photographers talk about 大光圈 (wide/large aperture, small f-number like f/1.4) and 小光圈 (narrow/small aperture, large f-number like f/16). Counterintuitive: a larger aperture number actually means a smaller opening.

memory

光 (light) + 圈 (ring/circle) - literally 'light ring,' the circular opening that lets light through.
