1. Canon 7D aperture adjustment steps
1.Set the camera to aperture priority mode (Av mode) or manual mode (M mode): The aperture adjustment of Canon 7D is mainly performed in aperture priority mode or manual mode. Select Av or M mode via the mode dial.
2.Use the main dial to adjust the aperture value: In Av or M mode, the aperture value can be adjusted by rotating the main dial on the back of the camera (located near the shutter button). Aperture values are usually expressed in f/numbers, such as f/2.8, f/4, f/5.6, etc.
3.Look into the viewfinder or LCD screen: When adjusting the aperture, the current aperture value will be displayed on the viewfinder or LCD screen, allowing you to check it at any time.
4.Shoot and check the effect: After the adjustment is completed, press the shutter button to take a shot, and check the depth of field and exposure effect of the photo through the playback function.
2. Things to note when adjusting aperture
1.The relationship between aperture and depth of field: The smaller the aperture value (such as f/2.8), the shallower the depth of field, and the more obvious the background blur effect; the larger the aperture value (such as f/16), the deeper the depth of field, and the clearer background.
2.The relationship between aperture and exposure: The smaller the aperture value, the more light enters, and the brighter the photo; the larger the aperture value, the less light enters, and the darker the photo. In Av mode, the camera automatically adjusts shutter speed to maintain correct exposure.
3.Lens aperture limit: Different lenses have different maximum aperture values. For example, the maximum aperture of the 50mm f/1.8 lens is f/1.8, while the maximum aperture of the 18-55mm f/3.5-5.6 lens changes with the focal length.
