Camera operation involves understanding how to use a camera to capture images effectively. The main components include the lens, which focuses light onto the sensor, and the shutter, which controls how long the sensor is exposed to light. Adjusting settings like aperture and ISO helps manage the brightness and clarity of the photo. To take a picture, you frame your subject in the viewfinder or on the LCD screen, then press the shutter button. It's important to hold the camera steady to avoid blurriness. With practice, you can learn to adjust settings for different lighting conditions and achieve the desired artistic effect.
