When using a photographic flash with a camera, the entire power of the light is nearly instantly dispatched, and very short shutter speeds can be used. With DT Stellar the power is increased to a higher power during the capture, and a longer exposure is typical. In some cases, such as shooting oversized material on a wall mount or large easel, several seconds of exposure time may be required. Stellar allows the user to increase the length of its flash to ensure it’s on the entire time the camera is exposing.
