What's the difference between flash high-speed synchronization and stroboscopic?

First, the shooting point is different.

1. High-speed synchronization: When using the high-speed synchronization function of an external flash, flash shooting can also be performed when the shutter speed is higher than the flash synchronization speed.

2. Flash: You can specify the number of flashes of the flash. It is best to use black cloth as the background.

Second, the advantages are different.

1, high-speed synchronization: When you want to blur the background and raise the aperture, the shutter speed is often higher than the flash synchronization speed.

2. Strobe: It is better to use black cloth as the background. It is widely used in commercial photography to shoot some moving objects, such as splash, movement, bullet flight and so on.

Third, the shooting situation is different

1, high-speed synchronization: about 2m away from the model. The bright reverse oblique light during the day forms a shadow on the model's face. I'm going to use a flash to eliminate it and increase the background blur. So as to obtain proper exposure when the aperture is opened.

2. Strobe: Turn off the indoor lighting at night and shoot under the dim brightness of people. Hang a black cloth behind the figure and try to remove unnecessary objects.
