Rapid calendering technology

1. In the studio, just use a black or dark background board/paper, plus the flash or light in the studio, you can brighten the main body.

However, in order to make the background darker, we can turn off or dim the indoor light source, keep the background as far away from the main body as possible, and avoid flashing lights to illuminate the background. The shutter should also be adjusted quickly to avoid absorbing living light. Flash output and aperture will affect the brightness of the subject and can be adjusted by itself. Remember, in a dark environment, the aperture/flash affects the brightness of the subject and the shutter affects the brightness of the background.

2. The principle of calendering technology is very simple. Use manual mode (M-Mode) to reduce ISO. First, measure the background light to reduce the exposure (the aperture is as small as f/ 16, and the shutter is set to 1/250 seconds, at which time the background becomes dark), and then illuminate the subject with a flash. However, it should be noted that the background has decided the aperture and shutter, and the outdoor sunshine is usually fierce. 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.

3. If we strengthen calendering and darken the background until the background is completely black, we can only use the flash to fill the light, so that we can take photos with dark background on either side. Most cameras have the maximum flash synchronization shutter speed, which is usually 1/200 seconds or 1/250 seconds. Our shutter speed must be equal to or less than this number, otherwise the photo will appear half black and half bright.
