Detailed explanation of photography skills on black background

1, adjust the shooting angle and find the background: because it is a black background, we try to choose a dark background before shooting, which makes it easier to achieve the effect. But dark color doesn't have to be pure black, the darker the better. Observe more before shooting, look for different shooting angles and find a dark color with strong contrast as the background. Try different angles until the subject is set off by a dark background, even if the area is relatively small. And this small piece of dark background can take pictures with pure black background.

2. Use propeller black background cloth: Whether it is portrait photography, commercial product photography or flower photography, making black background with black background cloth is the simplest and most effective method. It is a simple and convenient method to put down the black background cloth directly when shooting people or products. When you go out to shoot flowers, the black background cloth is easy to carry, and you can also use black clothes or a black umbrella. Pay attention to two points when shooting: the black background cloth should not be too close to the main body, otherwise the details of the black background cloth will be clearly photographed; Secondly, the depth of the field of view needs to be very small, so that the details of the negative are suitable for virtual. The usual method is to open the aperture or shoot with a long focal length lens.

3. Spot metering+selecting dark background+subtracting exposure compensation: It is more skilled to take photos with black background by spot metering. Spot metering is the best method when we don't wear background cloth. Before shooting technology, the principle of photometry is added: the camera photometry system is generally based on the reflection of 18 neutral gray, and high reflectivity will reduce the light, such as shooting white snow at the actual gray snow; Too low reflectivity will make the light brighter, for example, if it is aimed at a black object, but it is not black enough. The light with a small area in the spot metering measurement picture accounts for about 3% of the area, which gives priority to ensuring the correctness of the exposure of the subject. When we measure the light in the bright spot of the picture, the dark part of the picture will darken, forming a black background.
