Composition and lighting skills of modern art photography

Artistic photography is a visual art that forms a static two-dimensional image through the decisive moment of exposure and imaging, and then shapes vivid light and shadow images to express meaning through darkroom processing, or embodies artistic conception and meaning through conceptual images. This paper mainly expounds how to grasp modern art photography from two aspects: composition and lighting skills!

First, composition

Composition is the foundation of all visual arts, painting pays attention to composition, and artistic photography also puts composition in the supreme position. Many excellent photographic works have impeccable compositions, which attract many eyeballs and have a strong impact on people's vision and soul. Learning composition, analyzing composition and being good at composition are important factors to improve shooting skills.

(A) the treatment of light

The dynamic characteristics of camera light are not only determined by the technical requirements and modeling characteristics of camera shooting, but also closely related to the different requirements of different content for light. In documentary images, such as documentaries, scenery films, documentary feature films, etc. Usually, it is required to reproduce the typical light effects in the typical environment without distortion, pay attention to the use of light in real life, and emphasize the real and natural light effects. However, the light consumption of artistic images is more complicated and diverse than that of documentaries, which can be handled manually as needed, but it should be properly mastered according to the different shooting contents and program genres.

(2) color processing

Color can affect our mood, for example, shooting red can make people feel happy and unrestrained, green can make people feel quiet and peaceful, and white can make people feel terror and death. When shooting, according to the needs of the theme and content, choose colors with distinctive emotional characteristics and clear relationships, and match, combine and use them appropriately and flexibly.

(C) the treatment of tone sandhi

It is very important to do a good job of light and shade configuration in image composition. When we choose the subject in the picture, putting a small shadow tone in a large area of bright shadow tone or appearing a small bright shadow tone in a large area can attract the audience's visual attention and help to express the object or subject to be emphasized. The arrangement of light and shade can also be used to balance the composition of the picture. If one side of the picture is very dark and the other side is very bright, properly adjusting the relationship between light and shade by composition can change this unbalanced situation and make the structural form of the picture stable and balanced.

(4) Processing of lines

In composition, the beauty of lines depends largely on their relationship with the frame of the picture. For example, shooting the same flagpole, although it is upright in real life, it can occupy the center of the picture in the picture frame of the TV screen, or it can cut the picture beside it, giving people a different feeling.

Second, the use of light skills.

(1) Take photos of sunrise, sunset, sunny and snowy scenery, night scene when the lights start, and the rising of the moon at dusk. Read the sky value with center focus or matrix photometry, and expose it accordingly, you will be pleasantly surprised! The biggest trouble of shooting sunrise and sunset is that the sun plays a strong interference role in the picture, which makes the picture underexposed. At this time, aim the camera at the sun, and the picture does not contain the sun. Read the value, that's it! Your exposure is correct. Under the snow scene, if you use the conventional central key exposure, it is often that the snow turns gray, no problem. Reading the blue sky value can easily get the exposure compensation of troubles. But this method has a taboo: cloudy days. Don't look at cloudy days, or you will die miserably.

(2) Always look at the green grass and trees. Meet waterfalls in the forest and fields in a cloudy world. The central key metering mode frames the whole picture with green plants, reads the numerical value, and then compensates from -2/3 (normal green) to-1.3 (dark green), which is the correct exposure value.

(3) Hold out your palm, it's your ashes. When you are not sure about exposure value, under the same lighting conditions, stretch out your palm, fill the whole picture or almost the whole picture with your palm, read the data with the central key, and then make +2/3 shift compensation (film machine). In many cases, D70 may have to be compensated by+1 file. This is your exposure data.

(d) The general principle of digital photography should be that portraits should not be underexposed and landscapes should not be overexposed. In portrait photography, the audience's eyes require high transparency of the picture, have low tolerance for noise, and pay little attention to background exposure. At this time, the subject's face is required to be smooth and free of impurities, and a little overexposure is helpful to eliminate the spots on his face. Even if overexposure requires post-adjustment, as long as the face is not washed white by highlights, reducing exposure will not increase facial noise. Landscape photography emphasizes tone levels, and has a high tolerance for the overall noise of the picture. Therefore, as long as there is no highlight washing in the early stage, landscape photos with rich levels, bright colors and moderate noise can be obtained through adjustment and modification in the later stage.

Some suggestions on reasonable photometry in digital photography;

1. To shoot a snow scene, you can first press the shutter by hand, that is, measure the skin, and then press the shutter of the kind of snow you want to shoot, so that the snow will be white. Similarly, when taking a portrait in black and white, you should measure your face first, and then take a composition.

2. When shooting bright objects, the aperture should be higher than the index recommended by the exposure meter 1 ~ 2, while for dark objects, the exposure should be reduced appropriately.

3. Taking photos in sunny seasons will bring great contrast to the photos, so it is necessary to measure the light of the bright and dark parts of the scene separately and take photos with their average exposure index.
