How can we show the value of photographic works?

1. Lighting skills in landscape photography The importance of light for photography is self-evident. In landscape photography, with the illumination of light, the picture will produce light and dark levels, lines and tones. Taking pictures of scenery, we mainly use ether sunlight as light source. Different positions of the sun have different effects on the scenery. Next, the different effects of several different lights are introduced. 1. Guang Shun's influence on scenery In landscape photography, shooting scenery with Guang Shun can give people a bright and clear feeling. However, the lighting along the light is too flat, and the distinction between light and dark is not obvious, which often makes the color of the main body of the scene blend with the background, and the picture lacks three-dimensional sense. However, for beginners, the use of smooth light is relatively simple Photographers can basically take satisfactory photos as long as they use the camera's evaluation metering mode. The use of smooth light with an aperture of F7. 1 exposure time1180s and a focal length of 40mm makes the picture bright and clear. 2. The influence of sidelight on the scene; sidelight is a form that is widely used in landscape photography. In particular, the front light with a 45 angle can not only make the scene have a certain contrast between light and shade, but also enhance the three-dimensional sense of the scene and the shadow level of the picture. At the same time, the color reproduction of the picture is also ideal. 90-degree side light can halve the brightness of the scene, and the contrast between light and shade and the three-dimensional sense of the picture are very obvious. Especially in the performance of buildings and other objects with uneven surfaces, the effect is more prominent. When shooting with sidelight, the photographer should try to measure the brightness of the picture to avoid local overexposure. The use of sidelights with an aperture of F 1 1 exposure time 1/60s and a focal length of 70mm enhances the contrast between light and shade of the picture and enhances the stereoscopic impression of the picture. 3. The effect of backlight on scenery is the most unique light in landscape photography. Backlight means that the sun shines from the back of the camera, and the illuminated scene will produce a bright outline, so that the subject and background can be clearly separated. Backlight is most suitable for scenes with multiple levels before and after, and a fine contour light is outlined behind each scene, so that there is a strong sense of spatial distance between the front and rear scenes and a good perspective effect. When shooting a backlit scene, the picture is often underexposed due to the sunlight and the bright outline of the scene. Therefore, when a photographer shoots a backlit scene, it is best to determine the exposure time through the dark part of the scene, so as to fully show the level of the scene. If the photographer wants to get the effect of silhouette, then the bright part should prevail when shooting. Aperture F6.3 exposure time1160s focal length 80mm sensitivity 100 backlight condition, the straits and rocks irradiated by radiation produce heavy shadows, and the whole sea surface creates a sense of loneliness. 4. The role of highlights in the scene highlights generally refer to the light that the sun shines almost vertically on the ground between 10 morning and 2 pm. Highlight is the strongest time of the day, which will cause a deep shadow on the screen. At the same time, the highlight has a certain verticality, which is not conducive to expressing the texture of the object except the top-down shadow level. So this kind of light is not very suitable for expressing landscape themes. Exposure time of aperture F811250 s The tone of the rock irradiated by strong light with focal length of 44mm is very tough. 5. The influence of scattered light on the scene Scattered light generally refers to the light emitted when the sun's rays are blocked by thin clouds on cloudy days. Shooting in this light, the subject has no boundary between light and dark, will not produce shadows, and can only show dull object images and gloomy atmosphere. Therefore, in the case of cloudy light scattering, photographers need to narrow the scope of the scene as much as possible and take a close-up shot of the middle scene or local scene to obtain a clearer effect. At the same time, according to the actual needs, using a larger aperture or increasing a certain amount of exposure compensation can avoid underexposure caused by light turbidity. Aperture F5.6, exposure time1125s, and focal length of 40mm, the terrace scene with scattered light is flat in color and soft and bright in color.
