Slow Sync Flash Mode is a feature that enables photographers to use a flash together with slower shutter speeds. In this mode, the shutter remains open for longer, allowing more background light to be captured. This mode is a powerful tool for professionals and hobbyists looking to enrich their photography.
When using Slow Sync Flash Mode, you also have the option to choose when the flash will fire. You can choose to fire the flash at the start of the exposure, also known as ‘front curtain’, freezing the subject at the start of the motion. Alternatively, firing the flash at the end of the exposure is called ‘rear curtain’, letting you freeze the subject at the end of the motion.
Slow Sync Flash Mode is useful in low-light situations where both your subject and the background need to be lit. The slow shutter speed allows you to sharply capture your subject, and also take in ambient light in the background.
It is often a good idea to use a tripod when using Slow Sync Flash Mode as it will give the additional stability needed to enhance your shot.
