apertures
1
光圈, 孔径
the opening in a camera's lens that controls the amount of light that enters the camera and reaches the sensor or film
Aperture refers to the adjustable opening in a camera lens that controls the amount of light entering the camera. It is measured in f-stops, with smaller f-stop numbers indicating a larger opening and more light, while larger f-stop numbers mean a smaller opening and less light. Aperture also affects the depth of field, which determines how much of the image is in focus from foreground to background. Adjusting the aperture allows photographers to control exposure and the sharpness of different parts of the image.
- She widened the aperture to f/1.8 for a blurred background in her portrait.
