How to take photos of Buddhist beads with a pure black background

1. Indoor shooting

Find a stand and hang a dark or black cloth on it as a background. The cloth is preferably a light-absorbing cloth to ensure that the light only shines on the subject. without reflecting light. Set the shooting mode to aperture priority, set the aperture value around F8 and ISO100, and you can basically get a photo with a pure black background.

If the photo you get does not have a pure black background, use the "white plus black minus" principle to reduce exposure compensation. You can also shoot in M ??manual mode. Under this function, exposure compensation cannot be used. You can observe the changes in the screen light meter index in real time to determine the camera exposure.

2. Outdoor shooting

1) Use black cloth or black objects

When going out for macro or flower close-ups, you can put a piece of cloth behind the subject Use black cloth or black objects as the background. If conditions permit, you need a person to help hold the black cloth or black object and keep a certain distance from the subject (SLR photography control: smmapp). When shooting, choose a close-up or use a telephoto lens to avoid Unrelated things come into view.

2) High light ratio scene

If you don’t bring any black cloth or objects with you when you go out, and you want to take photos with a pure black background, you need to find a high light ratio scene. A large light ratio means that the brightness difference between the subject and the background is relatively large. If you find a scene with a bright subject and a dark background, it is easy to take a photo with a pure black background.

For example, the background is shaded and not exposed to direct sunlight, or the background is dark and the subject is exposed to direct sunlight. When shooting, constantly adjust the shooting angle so that the subject falls on the dark background as much as possible. If you cannot find a scene with a high light ratio, you can use a flash to fill in the subject to create a suitable scene for shooting.

Select spot metering and place the metering point on the brightest area of ??the subject for metering, which can ensure that details in the highlights of the subject are preserved. Use aperture priority to shoot. If the background you get is not pure black (SLR photography control: smmapp), you can lower the exposure, so that the background will become black due to underexposure.
