flitsers

Flitsers are devices that emit brief bursts of light used to illuminate a scene in photography and filmmaking. The singular flitser is a flash unit; plural flitsers. They range from small, built-in units integrated into compact cameras to larger external units that can be mounted on camera hot shoes or stands, and studio strobes used in professional studios. The earliest photographic flashes used magnesium or explosives; electronic flash became widespread in the mid-20th century, replacing powder flashes.

Most flitsers produce brief light pulses measured in milliseconds, with color temperatures near daylight (about 5400–5600 K). They may be powered by AA batteries, rechargeable packs, or mains-powered power packs. Modern units often support TTL metering, which uses camera information to set flash output, and manual mode for creative control. They may also offer high-speed sync, allowing flash photography at higher shutter speeds, and adjustable zoom heads to match lens focal length.

Common configurations include: pop-up or shoe-mounted speedlights for on-camera use; ring flashes for macro photography; and studio strobes or monolights for off-camera lighting with softboxes or umbrellas. Wireless triggering via radio or infrared allows multi-light setups with synchronized output.

Flitsers have a range of applications, including portrait, fashion, macro, and event photography. In cinematography, electronic flashes are sometimes used for strobe effects or to freeze motion. Safety concerns include avoiding direct eye exposure to intense light and using appropriate heat management to prevent overheating.

Etymology: flitser derives from Dutch flits, meaning flash. The term is used primarily in Dutch-language contexts; in English, “flash” or “flash unit” is common, with similar devices known as speedlights or strobes.
