Three basic knowledge of photography
1, exposure: exposure means that light enters the camera, the amount of light entering is controlled by the aperture, and then the exposure time of light is controlled by the shutter time. The control of exposure determines the brightness and color of photos.
2. Focal length: Focal length refers to the ability of the optical elements inside the camera lens to enlarge or narrow the scene. The wide-angle lens has a short focal length and can shoot a wider scene; The telephoto lens has a long focal length and can shoot farther scenes.
3. Shutter: Shutter refers to the time required for light to enter the photosensitive medium through the lens and be fully exposed after the camera aperture is opened. The faster the shutter speed, the shorter the exposure time, and the clearer the photos or freeze-frame actions; The slower the speed, the longer the exposure time, and the trajectory of light entering the camera will lead to blurred or flowing effects.
If you master these three basic knowledge, you can better understand and master photography skills and apply them in practice.
Photography is a combination of art and technology, and we should pay attention to the following aspects:
1, shooting angle: Choosing shooting angle is an important part of composition. A reasonable angle can make photos more layered and atmospheric, and can also highlight the theme and creativity.
2. Choice of focal length and aperture: It is very important to choose the appropriate aperture and focal length according to the needs and light conditions. The depth of field can be adjusted according to the settings of light and aperture to make the shooting effect more vivid.
3. Exposure control: Excellent exposure control can make the brightness and color of photos more accurate. It is necessary to choose shutter speed and aperture size according to the photographic scene and photographic equipment experience to adjust the exposure of photos.
4, focusing skills: focusing is the key to half the success, you need to focus carefully, such as setting the focus, using focus locking and other means to ensure that the shooting angle and focus are more accurate.
5, the use of light: light is an important factor in the creation of photographic works, we need to work hard on the control of light, such as using reflectors, adjusting angles and time. To optimize photo contrast and environment layout.
In a word, photography needs care, concentration and patience, artistic inspiration, mastery of photography technology and post-processing of results, all kinds of thinking and observation, and in-depth insight into artistic inspiration and technical points contained in various elements.
