Dependent claims

A method of controlling an LED lighting device, the lighting device comprising an interface, the method comprising:

receiving, via the interface, information relating to a shutter speed setting of said camera;
determining, from said information, whether the shutter speed setting is faster than the camera's native sync speed;
and
if it is determined that the shutter speed setting is faster than the camera's native sync speed:
determining a shutter open period for said camera, said period corresponding to the period where at least part of the camera's sensor is exposed;
and
controlling the LED lighting device to emit a continuous flash, synchronised with the determined shutter open period, such that the flash provides continuous illumination for the entire duration of the shutter open period.
