Photography skills

The stability of the camera is very important when shooting, because the jitter may affect the quality of the photo. If possible, it is best to use a tripod to stabilize the camera. If there is no tripod, the photographer can lean against the wall or put his hand on the railing to keep the camera balanced. The shooting angle is an important factor in the visual effect of photos.

For example, when taking portraits, shooting from the height of the eyes can produce the most comfortable effect. Shooting at a low angle can make people look taller. Depth of field is the clear foreground and background range in a photo. The depth of field can be changed by adjusting the focal length and aperture of the lens. Shorter focal length and larger aperture can produce shallower depth of field, while longer focal length and smaller aperture can produce deeper depth of field.
