How to take outdoor photos with bright subject and dark background?

There are two main techniques for taking pictures of dark backgrounds and bright subjects:

1. Use a black background in the studio.

2. Use flash lamp for outdoor calendering.

First, use a black background in the studio.

In the studio, just use black or dark background board/paper, plus the flash or light in the studio, the main body can be brightened. In order to make the background darker, you can turn off or dim the indoor light source. The background should be as far away from the main body as possible to prevent the flash from illuminating the background, and the shutter should be adjusted quickly to avoid absorbing living light. The output of the flash and aperture will affect the brightness of the subject, which can be adjusted by yourself. Remember, in a dark environment, the aperture/flash affects the brightness of the subject and the shutter affects the brightness of the background.

Second, the flash for outdoor calendering.

The principle of calendering technology is very simple. Use the manual mode (M-Mode) to reduce ISO, first measure the background, reduce the exposure (when the aperture is as small as f/ 16, the shutter is set to 1/250 seconds, and the background becomes dark), and then use the flash to illuminate the subject. However, it should be noted that the outdoor sunlight is usually strong because the aperture and shutter have been decided by the background. The flash needs the maximum output (manual11) to make the subject have enough brightness. If it is not bright enough, you can move the flash closer to the main body. In order to make the main body have better effect, it is suggested to use the soft light equipment of flash.
