Many friends may be confused. Why do you get an external flash, the camera''''''''''''''''''''''''''''''''s shutter speed cannot be improved, the fastest shutter speed is limited to 1/200 or 1/250 seconds.
This is not your camera problem, because your flash does not support high speed synchronization.(HSS / FP)Function.
Simply put, a flash of high-speed synchronization can work at any shutter speed, without a high-speed synchronization function, can only work at 1/200 or 1/250 shutter speed.
High-speed synchronization has a wide range of application scenarios. You can first imagine that it is used for sports high-speed photography. Only high-speed shutters can clearly solidify the movement of athletes, and 1/50 seconds is clearly not enough.
Temporated water droplets also require high speed synchronous flash.
Shoot animals, especially small birds or flight insects, high-speed synchronous flashes are also indispensable.
High-speed synchronization is more commonly used in balancing filling flash:
When you have a strong outdoor, shoot backlight portraits, you need to illuminate the characters through the flash, so that the characters and the sky behind the sky are consistent.
But this time, even if you reduce the aperture, reduce ISO, it is also likelihood that the sky is not exposed at 1/250.
The following figure shows three cases respectively:
- The character exposure is accurate, background exposure;
- Background exposure is accurate, the character is underflocking;
- Flash high speed fills flash, balance exposure.
You must ensure that the sky is accurately exposed by improving the shutter speed. At this time, the flash must have a high-speed synchronization.
This is what the flash friend is often said:“ pressing the sun with flash&RDQUO ;.
If you have a flash without a high-speed synchronization, you will get a full black picture under the high-speed shutter.
