How to use light reasonably in photography.

Photography is an art of light and shadow, and we will even judge the photographer's photography level by examining his ability to use light. There are different types of light. By understanding the difference between these lights and using them according to your own understanding, this is called light control. The most basic and effective way to improve your light control ability is to learn to make good use of natural light. The following are my carefully recommended light and shadow shooting skills, hoping to help you.

Rational use of light

Soft light: There is a saying in photography that the light around sunrise and sunset is "golden light" because the light at that time was very warm, soft and golden yellow, which is the most common soft light. However, it should be noted that although soft light is deeply loved by everyone, it is not suitable for all styles of portrait photography. The use of light depends on the theme of the work, not all scenes are shot with soft light.

Strong light: a kind of light opposite to soft light, called strong light. Not only does it mean that the light is very strong and dazzling, but it means that the contrast is strong and it is easy to cause deep shadows. Dazzling glare will enhance the visual effect of some shading and greatly improve the color saturation, which is suitable for highlighting a subject or emphasizing the contrast effect of the picture. We also need to pay attention to: when shooting under strong light, the sharp contrast between the bright part and the dark part in the picture may make the camera unable to expose accurately, resulting in the loss of some details in the image, that is, to ensure that the bright part is exposed normally, but the dark part is underexposed, and vice versa.

What is color temperature?

*** 1*** blue light * * about 1 100k***

The time is 2 hours before sunrise and 2 hours after sunset. The characteristics presented are: blue usually gives people a feeling of melancholy and calmness, which can calm the viewer's mood, but also has the meaning of coldness and silence. It is suggested to try when shooting: pay attention to observation when shooting, and try to mix the blue cold light with other bright colors at that time. The combination of colors will produce amazing works. Note: the light is weak at this time, so pay special attention to your aperture, shutter and camera ISO to avoid underexposure or blurred image.

***2 yellow gold threads * * * about 3500k***

Generally, the time is at sunrise and sunset, showing the effect of soft and warm colors that make people feel warm and comfortable, and it also has incredible performance in landscape photography. When shooting, it is recommended to try: stand slightly higher than your subject, shoot at a 30-degree angle, capture the light projected from the sky into the eyes of the subject, and make the model beautiful and moving. Note: If you want to shoot a work in this light, you need to plan ahead, because the golden time is very short and fleeting, and you must finish the work efficiently in a very short time.

***3*** Ordinary daylight * * 5000-6500k * * *

The time is from sunrise to sunset, which shows that this is a very neutral light effect, without obvious color temperature and tone, but the light intensity will be higher, which will enhance the color and brightness of the object itself. It is suggested to try it when shooting: although the light of the sun tends to be white and has no characteristics, you can adjust the color temperature of the camera and try different effects. Note: at this time, the light is very strong, so pay attention to the overexposure of the picture.

***4*** Cloudy day * * * About 7000k***

The time is mainly on cloudy days, and the effect is somewhat similar to the melancholy blue light, giving people a gloomy and deep feeling, which can be used to express a relatively low shooting theme. It is recommended to try it when shooting: you can shoot in the rain, where the light is soft but slightly dim. Note: at this time, it is necessary to observe whether the background color conforms to your theme. The gloomy sky in the picture is not conducive to expressing cheerful emotions.

Use on-site lighting

Light is the most common means to participate in composition, especially when shooting pictures with environmental scenes. Using light can highlight people and core content and avoid clutter or parts that are not conducive to expressing the theme.

Let light choose what to express and how to express it. The urban space is relatively complex and the streets are narrow, so it is easy to feel messy when shooting large scenes. Effective use of light can complete the distinction and selection of the environment; The countryside is often empty and loose, so it is difficult to form a concentrated and distinctive composition style. We can use natural light to combine the characteristics of the environment and landforms to form a light and dark area with a sense of lines to avoid the looseness and unfocused picture.

In the scene with large contrast of light ratio, the position of people is usually selected in the highlighted area, and people should be arranged in the interest center or visual center according to the relationship between light and shadow, the characteristics of picture lines and the law of composition. All ideas, ideas and prerequisites are light.

To conceive a painting, we must first determine the intensity, texture and direction of the light in the environment, what content to show and what feeling to create under this condition, and then the style of composition, the position and posture of the characters and the setting of the situation.

It should be noted that it is difficult for you to change the existing light structure in a large scene. More importantly, you can balance the picture by choosing the angle and the scene. Sometimes you can use some special elements to create a foreground and change the proportion and characteristics of the original picture.
