synchroflash
Học thuậtThân thiện
Definition
Noun: A device used in photography to synchronize the peak of a flash with the opening of the camera shutter. It ensures the flash fires at the exact moment the shutter is fully open, allowing for proper exposure of a photograph.
Usage
A synchroflash is a technical component, either built into a camera or an external flash unit, that coordinates timing. It is used to prevent issues like partially dark images when using flash photography with fast shutter speeds.
Examples
- The photographer relied on the camera's built-in synchroflash for the indoor portrait session.
- For this vintage camera, you need to attach an external synchroflash unit to use a flash bulb.
- Modern electronic flashes have an integrated synchroflash circuit.
Advanced Usage
- X-sync (Flash Synchronization): This is the modern technical term for the concept and function a synchroflash provides. It refers to the camera's maximum shutter speed at which the entire sensor/film is exposed at once to sync with a flash.
- Synchroflash Contact/Port: The physical point on a camera where a flash unit connects to engage the synchronization.
Variants and Related Words
- Flash Synchronization/Sync (n): The general process or capability that a synchroflash enables.
- Synchronizer (n): A more general term for any device that causes two or more events to coincide in time.
- PC Sync Socket (n): A type of connector on a camera for attaching a flash cable to achieve synchronization (historically called a Prontor-Compur socket).
Synonyms
- Flash synchronizer
- Sync device
Notes
The term synchroflash is somewhat dated and is more commonly encountered in the context of older photography equipment, particularly from the mid-20th century. In contemporary photography, the technology and function are standardly referred to as flash synchronization or X-sync.
