Abstract: A remote control is described for controlling at least one group of flash devices for photography. The remote control is configured to send a pre-flash trigger signal, TPF, to the flash devices for initiating a pre-flash (PF), and to receive, from the camera, a flash adjustment value, VA. The remote control comprises a display and is configured to determine a main flash strength value, VMF, based on a pre-flash strength value, VPF, stored in the remote control, the flash adjustment value, VA, and a predetermined relationship between the pre-flash strength value, VPF, the flash adjustment value, VA, and the main flash strength value, VMF. The remote control displays the main flash strength value, VMF, on a display and sends a wireless main flash trigger signal, TMF, to the flash devices, for initiating a main flash, MF, with adjusted flash strengths.

Abstract: A flash apparatus comprising at least two flash tubes and at least two energy storage units is presented, wherein each of said at least two energy storage units is being arranged to be configured to strictly correspond to one of the at least two flash tubes for a flash. The flash apparatus is configured to control the amount of energy provided by the at least two energy storage unit(s) to their corresponding flash tube and control the flash duration of the corresponding flash tube dependent of each other, respectively for each flash tube, so as to obtain substantially the same colour temperature from each flash tube for a flash. A method and a computer program product for use in the flash apparatus are also presented.
