How to take a simple black background photo?

Lead: Has it always been popular in the photography circle? Big aperture worship? The reason is that it not only creates an oily blur effect, but also brings a useful addition, that is, simplifying the background. There is a multidimensional spatial relationship among foreground, subject and background in photography. If the background is messy, your subject will be blurred no matter how bright it is. At this time, if you want to take a good photo, you can start with the relationship between photometry and exposure and take a simple solid color background photo.

How to take a simple photo of Hongshan with a black background?

Solid color background is often used to avoid complex shooting environment, whether outdoors or indoors, you can get an unexpected sense of form with minimalist composition with only a little skill or props.

You must have seen many photos with black background like this. As the most commonly used background color of dark-tone photos, black background has the function of highlighting the subject and precipitating the tone, which is quite normal.

I believe everyone can think of the simplest way, that is, with the help of props, find the right black cardboard or flannel as the background and put it behind the lens main body. Pay attention to a certain distance When using macro or close-up, the background will blend into controllable all black.

Scenes with insufficient exposure or no light are shot like this.

In the case of sufficient light, the same scene is shot like this.

The second method needs to understand the exposure principle. We often say that photography is the art of light, and exposure can only use light. If there is no light or the amount of light is small, the photos taken are black. So we can draw a conclusion that the exposure of normal photos is uniform, because the points in the picture are different; All the black backgrounds appear because that place is underexposed.

Aperture: F2.8 Shutter:11250 seconds ISO: 100 Exposure compensation: -5 EV (works by Wu Nannan, a photography tribe)

Therefore, combining the basic knowledge of photometry and EV adjustment in photography, we can use aperture priority or shutter priority mode to point out the subject to be represented, aim at the brightest part of the subject, and then reduce the exposure compensation 1 to 5 exposures, and the background will turn black due to insufficient exposure.

? The third method is reverse thinking. In order to make the background black, the subject and the background need to have a bright and dark contrast, but many times the background is not dark. This requires us to add a strong light source (such as a flash) and control the unit light intake and shutter speed to achieve the effect of instantly brightening the subject. In this way, compared with the brightness of the background, there is a contrast and the background naturally darkens.

Judging from the above photos, the exposure of leaves and butterflies is normal because of the flash, so the background is black; And because the flash can't hit the background area, the background is underexposed. In addition, it should be noted that when using flash and other light sources to brighten the subject, it is best to keep a certain distance from the background, and the farther away, the better the effect, so as to brighten the subject better.

If you are interested in the above methods, you might as well try them all. Generally speaking, the subject should be clear and concise when taking photos with all-black background. It is best to use artificial light sources such as flash lamps in the environment with large light ratio, which can create a variety of shooting methods. While reviewing the knowledge of exposure and photometry, we can also try the classic skills of Taskmaster's drawing.
