How to set the flash to Hou Lian synchronization?

Hou Lian synchronization: shutter front curtain open-flash-shutter? Hou Lian is closed.

Characteristics of Hou Lian synchronization: When shooting a moving object, a series of ghost images will be left on the screen because the shutter has been opened, and then the flash will flash to "freeze" the last frame of the motion. That is to say, ghosts are behind the moving direction of moving animals.

It is very difficult to take photos of multiple children in the same picture, because in most cases, at least they will do some "little tricks" that interfere with the picture more or less when shooting.

If you want them to be at their best for a long time, the best way is to shoot them while they are playing. At the same time, it also gives you a chance to capture the wonderful moments when they play, not just their expressions and actions.

The author of this photo is Brett Harkness, an expert in life photography. He told us: "I knew I wanted to use the low-speed shutter to show the boys' movements, so I used the manual mode and set the shutter speed to 1/20 seconds. The correct exposure value should be f/8, but I want to get a darker picture effect than usual, so I chose the aperture of f/ 1 1. "

Brett tilted his camera to a certain angle and set the flash to Hou Lian synchronization, which can freeze the child's motion at the end of exposure and create a blurred and dynamic image trace behind the child.

Brett said: "This technology will also help if you move the camera gently and quickly from side to side during exposure. It takes some practice to master it, but it can highlight the sense of movement of the picture well. I often say that this is to use the jitter of the wrist to pan. "

Brett said: "Decreasing the shutter speed and prolonging the shutter release time will allow you to record the motion trajectory of the subject."

Shooting skill

Set the camera to manual exposure mode and use a low-speed shutter, for example, 1/20 seconds. At this time, it is best to reduce the exposure by one step on the basis of the given exposure parameters of the camera. (that is, the aperture value is increased by one step. ) Set the flash to Hou Lian synchronization and adjust the flash power to+1EV. Parameters can be fine-tuned according to the field light. Tilt your camera when shooting and pan with the motion track of the subject, which requires a lot of practice.
