FAQ
Frequently Asked Questions
Yes, 'open flash' is essentially a synonym for 'slow sync flash'. It describes the technique of using a slow shutter speed (open shutter) while triggering a flash.
You need a camera that allows manual control over shutter speed and a flash that can be triggered manually or via the camera's hot shoe. Most DSLR and mirrorless cameras are capable.
'Open flash' is the general technique. 'Rear-curtain sync' is a specific type of open flash where the flash fires at the *end* of the exposure, just before the shutter closes. The alternative is front-curtain sync, where it fires at the start.
No, it is a specialized technical term used almost exclusively in photography. The average speaker would not be familiar with it.
