The role of light in photography

There is a sentence in the photography circle: "Photography is the art of light." There are many factors that determine the quality of a photo, subject, structure, color, etc., which is the most important factor in light.

When Dawn arrived, we opened our eyes, and the first bunch of light in the morning came into our field of vision. "Light" is everywhere and changes over time.

People are also extremely sensitive to light sensitivity. The light sources of different times and different strength directly affect our angle and authenticity of our observation of the world.

For example, we have countless verses that praise the sunset, but we rarely appreciate the mood of noon. Because the sun at different times has different orientation, the light that is illuminated is different.

This principle is also established in the camera, and the camera's lens is our human eyes. The strength of light, the angle of light, and even the color of light will have a huge impact on photography.

If you want to take a picture of an artistic atmosphere, the use of light needs to be polished repeatedly throughout the photography process.

When we walk into any environment, a dense forest or a hut with sufficient light in the room, we need to determine the surrounding light elements in a short time, and then think about how to use it.

Consider the direction, brightness, time, and the color and shape of the surrounding environment, the ground, wall, etc. If you want to shoot portraits with this background, you need to consider more. Whether to borrow natural light, or artificial filling.

The combination and adjustment of these light elements and environmental elements will determine the quality of the final film. Therefore, understanding the specific role of light in photography is the prerequisite to correctly adjust the combination of light element.

The role of light in photography is mainly reflected in three aspects, the role of exposure, styling, and the role of shooting.

1. Style

In photography, light is the media, and the scenery is displayed in the camera through light. Therefore, the lighting of photography, the rendering of environmental atmosphere, and the expression of ideological feelings are of extremely important significance.

We say that photography is artistic with light, and the shape and light are obedient. "Light" has a vital role in the artistic performance of styling.

In the photography creativity, there must be a sense of "light" and mobilize the shape of the light to shoot the desired artistic effect.

The light in nature is ever -changing, complex and delicate. In the day, the sun continues to change the direction and angle of the incident with the change of time, and it will bring different effects in the photography shape.

Mastering the shape of the light, you have mastered the skills of light. In photography, light is not only the prerequisite for lighting, but also an important condition and factors for composition modeling. For the same scene, different light methods can produce different shapes, different effects, and express different theme ideas.

In natural light, we must continue to change the angle of the scene according to the direction of the light and change the different shapes in order to achieve the best use of light. In artificial filling, light needs to be continuously changed according to different character shapes.

2. Shooting the main role

In many cases, light can be used as the subject of shooting. The "light" mentioned here refers to the glowing source.

For example, the "sun", the sun and the sunset, are very beautiful natural phenomena. Its beauty shows a different sense of light at different times at different times.

These light feel shows colorful colors through the air and clouds. In the light and shadow of the camera, this colorful color is also presented in our artistic creation.

In this photo, "light" is the subject of shooting, the artistic nature of the photo is also "light".

In addition, the light that the sun projected in the dense forest, the light in the fog, the rainbow after the rain, and the solar eclipse can be used as the main body of the shooting. Different colors.

Of course, the light above is natural light, and the light sources come from the sun during the day.

When night comes, various lights in the room, the lights, moonlight, fire, fireworks, fluorescence, etc. at night can also be used as the main body of the shooting.

3. Exposure

The role of the exposure is mainly the color of the photo, or bright or dark. In the previous article, we talked about the three parameters of the adjustment exposure. That is, aperture, shutter, and sensitivity, the specific adjustment will not be talked about.

Reasonable exposure will affect the density and color of the image. The exposure and density must also master the effects of density on the effect of image.

Insufficient exposure photos

Density refers to blackness. The larger the exposure, the more sensitive the CCD/CMOS chip is, the lighter the blackness of the image, the smaller the density, and otherwise, the smaller the exposure.

In color photography, inaccurate exposure can easily cause color imbalance. Insufficient exposure, the color of the image is plain; excessive exposure affects the color and is not bright.

Only the exposure is accurate can we obtain images with rich colors, bright colors, rich layers, normal contrasts, and bright shadows.

Conclusion

As mentioned before, the essence of photography is "the freezing of light and shadow". The light and shadow language is the core of photography performance. Only by fully exerting the expression of the light and shadow language can the unique artistic expression of photography be used.
