There were many ways to light an indoor camera: - Single-light portrait shooting: Many photographers advocate single-light portrait shooting as if it was a sun. The light can be adjusted according to the subtle changes in the natural weather. Pay attention to the light, otherwise you can use the umbrella tool. Under strong light, the skin texture should be as good as possible. The position of the light should be on the person's head as much as possible. You can choose a soft umbrella to create a uniform light. - ** Multi-Light Portrait Shooting **: - In principle, there was only one main light source for multi-light shooting, and the other lights played a supporting role. For example, when two lights were used, one was the main light and the other was the supplementary light or auxiliary light; when three lights were used, one was the main light and the other two were the supplementary light or auxiliary light. - There were three points to note: First, soft light cover and reflective umbrella could be used according to the needs to soften the light; Second, due to the characteristics of the digital sensor, it may weaken the three-dimensional effect of the picture. In actual shooting, try to use a silhouette light to enhance the three-dimensional effect; Third, the actual shooting should be based on the distance and the characteristics of the light. - ** Double Lights Portrait Light **: A different way of light distribution from the traditional double lights is that the main light with a reflective umbrella is located at the upper left with 1/2 light output, and the auxiliary light with a soft light box is set on the right with full light output. The auxiliary light can emphasize the outline and the three-dimensional effect of the model, and the soft light can illuminate the rich details of the model. The exposure is based on the output light of the main light. This kind of light distribution was suitable for digital photography. It could make the main body of the model clear and three-dimensional. - ** Multi-light portrait lighting example (three lights)**: The traditional method is that the main light is softer on the upper left, there is an auxiliary light with a soft light box on the upper right, and there is a background light behind (suitable for a single-color background to make the background beautiful). The auxiliary light can enrich the details. This method of light distribution did not require high accuracy and was suitable for beginners. When shooting with many people or when the movement changes greatly, the main focus is on the direction and illumination area of the main light. Moving the main light can take photos with uniform light ratio. For example, two 1600W lights and a soft box were completely backlit. The front of the model was facing the direction of the mirror to illuminate the front and face. The backlit light outlined the outline of the model. The use of the mirror could make the model's face layered. When shooting, pay attention to the side light of the face and adjust it downward to prevent the outline light from disappearing and overexposing. - ** Common Light Type and Function **: - ** Main light **: It is the preferred light that determines the lighting pattern of the subject. It is usually emitted by the soft light box. The illumination distance and angle can be adjusted according to the needs. The exposure of the photographic image is determined by the main light. The main light could modify the face of the character, make up for the uneven skin color and the shortcomings of the face shape on the camera, and portray the appearance of the character to show the inner activities. - ** Fill-up Light **: It is used to supplement the lighting of the shadow part of the picture, making the shadow lighter. It is also emitted by the softbox. The photographer adjusted the power of the soft light box to control the depth of the shadow, so that the fill light and the main light formed the best light ratio. The soft box for fill light can be placed near the camera, on the other side of the main light, and at the same height as the lens to produce a uniform fill light effect. - ** Backlight **: Using the background as the light source. In most cases, there is a distance between the subject and the background. The function is to separate the subject from the background. The lamp should be behind the main body and higher than the main body. When using it, the color, distance, and lighting angle of the background should be fully considered and adjusted repeatedly. In addition, some special equipment could also be used for lighting. For example, when using a small portable projector as a light source, pay attention to its placement angle and strength. The projector is a hard light source. If you don't want the light to be too hard, you can use a soft light board in front of the projector, but it may sacrifice the clarity of the projected image. You can also use Christmas lights to hang it on the wall, so that the main character of the photo is in a position some distance away from the front. You can make shallow depth of field and beautiful bokeh effects by adjusting the aperture (f/1.4 - 3.5), using telephoto (50mm +), or close to the main character. There were also lighting techniques such as installing a 150B imaging lens and inserting an insert to emit window light, then adding a 500B ceiling light to make the light and shadow transition more natural, or using a 350W calfskin as a surface light, installing a spotlight in front of the lamp to emit window light, and then using foam boards to fill in the dark details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
