相机光圈怎么调

To adjust the aperture on a camera, you can typically do so by changing the f-stop setting. A lower f-stop number (e.g., f/2.8) will result in a larger aperture opening, allowing more light to enter the camera. Conversely, a higher f-stop number (e.g., f/16) will result in a smaller aperture opening, letting in less light.

You can usually adjust the aperture settings on your camera by selecting the aperture priority mode (usually denoted as "A" or "Av" on the mode dial) and then using the control dial to change the f-stop value.
