What are Slave Flash Products for Digital Cameras and Why are They Needed?

Digital cameras usually have an inadequate built in flash and lack any facility to use an external flash. Standard slave flash units will not work with most digital cameras because these cameras use a very rapid series of pre-flashes (we're not talking about red-eye reduction). The pre-flashes are used to set the white balance of the camera's CCD chip - not the exposure. A typical slave unit will fire on the first pre-flash it senses while the digital camera captures the image on the last flash. Thus the extra light from the slave does not show up in the digital camera photo.

Our slave flash units are specially designed to fire on the correct flash sensed by their built in optical sensor and circuitry, thus solving the digital camera flash problem. The Digi-Slave PRO, the Deluxe 3000, and the dual mode DSF-1s feature a switch on the back which allows the user to select between the two different triggering modes used by different digital camera models. This allows them to be used with any camera on the market. The new RF-50 Ring Flash has built in digital slave circuitry and needs only to be screwed on to the lens threads of your camera (specify camera when ordering). It's great for shadow free macro work such as dental and catalog photography. And since our slave flash products have built in digital slave circuitry, no electrical connection to the camera is required.

Using an Olympus D600L, the first photo was taken with no flash, the second with camera only flash, and third with the DSF-1 added.
