The photographic lamp is the most important accessory in photographic equipment. It is a necessary equipment for fill light shooting, and it is also one of the indispensable accessories in portrait photography. Today, the editor of LUXCEO Le Shi Ou shared how to use multiple LED photography lights to build artificial light sources for shooting.

1. The characteristics of the fill light

Luminosity: Luminosity in photography refers to the brightness of the surface of an object illuminated by a light source. The luminosity is closely related to the type, nature and luminous intensity of the light source, the irradiation distance and the physical characteristics of the surface of the subject to reflect light.

2. There are two types of light sources used in photography: natural light sources and artificial light sources

•Natural light source, which is obtained through the sun's irradiation. The intensity of sunlight is constant, but it changes with the seasons, weather conditions, time, altitude, and geographic latitude and longitude.

• Artificial light source, as the name suggests, is the light used in various photography, LED photography light. Artificial light sources can ensure stable output, but have a close relationship with the distance. The closer the distance to the subject, the stronger the illuminance; the farther the distance, the weaker the illuminance.

3. Light quality, in terms of light characteristics, there are soft and hard light points

•Hard light: With obvious directionality, it produces clear and thick shadows, which can make the contour of the subject sharp and high contrast.

•Soft light: There is no obvious directionality, the shadows are softer, and the contrast of the subject is low.

4. light position

•Shun light: also known as front light, illuminating the subject from the front

•Side light: the light irradiated from the oblique side of the subject, usually divided into front side light, back metering and oblique side light

•Backlight: illuminate the light from the back of the subject

•Top light: the light from directly above the subject, such as the morning sun

•Foot light: light from below the subject

•Scattered light: light without a certain illuminating direction, such as natural light in a cloudy day, suitable for shooting portraits and remake prints

5.light type

•Key light: The main light of the subject, which plays a leading role in the performance of the shape, contour and texture of the subject.

•Auxiliary light: plays the main role, is to increase the height of the shadow part produced by the main light, so that the shadow part can also show the necessary texture.

•Contour light: the light used to outline the subject. Separate the object from the background to make the object more three-dimensional.

•Background light: the light shining toward the background behind the subject, used to highlight the subject or beautify the picture.

•Decorative light: It is used to decorate the part of the subject to better highlight the subject, and is mostly used to photograph jewelry.

6.light ratio

Light ratio, the difference between the light intensity of the bright area and the dark area on the subject. The biggest significance of light ratio to photography is the contrast between light and dark in the picture. The contrast is large, the visual appearance of the picture is strong; the contrast is small, the picture appears gentle and soft.

In portrait photography, contrast can well express the character of a character. High contrast appears strong and powerful, while low contrast appears soft and feminine. In landscape photography and product photography, the high-contrast texture is hard; the low-contrast shots appear plain and objective.

7.light color

Light color is the color of light and usually refers to color temperature. Different light colors will have different effects on the presentation results, which are of great help to the theme of performance. For example, red symbolizes enthusiasm, yellow represents nobility, and white symbolizes purity.

LUXCEO always insists on high quality and high cost performance. The company's mission is to provide photographic equipment products with diversified types and leading technology, and strive to provide suitable light sources for the majority of photography enthusiasts and film and television workers.
