A must see for beginners! 3 minutes to master the secret of camera parameters

Taking photos is not about casually pressing the shutter button. The parameters determine whether your photo is a pedestrian photo or a high-quality shot!

The core of mastering camera parameter settings lies in understanding the logical relationship between the three elements of exposure (aperture, shutter speed, ISO), and flexibly adjusting them according to the shooting scene. The following are essential parameter settings for beginners:

The logic of the three elements of exposure

Aperture (F-value): The smaller the F-value (such as F1.8), the more incoming light and the stronger the background blur (suitable for close-up portraits); The higher the F-value (such as F16), the less incoming light and the clearer the foreground and background (suitable for landscape photography).  ‌

Shutter speed: The smaller the value (such as 1/4000 second), the more it can freeze dynamic scenes; The larger the value (such as 1/30 second), the more suitable it is to record dynamic trajectories (such as car flow light tracks). Handheld shooting is recommended to be no less than 1/80 second to avoid shaking and blurring.  ‌

ISO sensitivity: 100-400 for daytime use to ensure image quality; Raise to 800-1600 when there is insufficient light to avoid noise explosion.  ‌

Selection of shooting mode

Aperture Priority Mode (Av/A): Manually adjust the aperture, and the camera automatically matches the shutter and ISO, suitable for portrait blurring scenes.  ‌

Shutter Priority Mode (Tv/S): Manually set shutter speed, camera automatically adjusts aperture and ISO, suitable for motion capture.  ‌

M mode: requires manual setting of aperture and shutter speed ISO， Suitable for complex lighting scenes. It is recommended to first lock the ISO (100-400 on sunny days, 800-1600 on cloudy days), and then adjust the aperture and shutter speed.  ‌

Practical operational skills

Accurate focus: When shooting portraits, manually select the focus point (such as the person's eyes) and activate the nine grid assisted alignment.  ‌

Safe shutter: When shooting handheld, it is recommended to use 1/focal length (for example, a 50mm lens requires 1/50 second or more).  ‌

Exposure compensation: white plus black minus, snow scene+1EV, night scene -1EV

Following these setting logic and flexibly adjusting according to different scenes can quickly improve the success rate of shooting.
