Estimating the term…
A flash lamp for underwater photography for use in combination with a camera has a target light, which may be a laser diode or a focussed LED and is set so as to emit a beam of light coaxially with its flash light source such that the user can visually ascertain where the lamp will illuminate. The lamp is controlled such that the target light is automatically switched off or made darker approximately simultaneously as the shutter of the camera is opened. If the flash lamp is of a kind which undergoes preliminary flash light emission prior to main flash light emission, the target light is controlled so as to be switched off or made darker by using the preliminary light emission as the trigger. If the camera is of a kind that outputs a ready signal when its shutter is pressed to a half-way position to indicate that it is ready to be clicked completely, the ready signal may be used as the trigger for switching off or darkening the target light.
A flash lamp for underwater photography for use in combination with a camera, said camera having a shutter, a shutter button for opening said shutter and a finder which defines a field of vision, said flash lamp comprising:
A method of controlling a flash lamp with a target light for use in underwater photography in combination with a digital camera, said method comprising the steps of:
A method of controlling a flash lamp with a target light for use in underwater photography in combination with a digital camera having a shutter and a shutter button for completely pressing down to open said shutter, said camera including means for outputting a ready signal when said shutter button is pressed to a half-way position prior to being completely pressed down, said method comprising the steps of:
A device for controlling a flash lamp with a target light for use in underwater photography in combination with a digital camera, said flash lamp being adapted to undergo preliminary flash light emission prior to main flash light emission each time a shutter of said camera is opened;
A device for controlling a flash lamp with a target light for use in underwater photography in combination with a digital camera having a shutter and a shutter button for completely pressing down to open said shutter, said camera including means for outputting a ready signal when said shutter button is pressed to a half-way position prior to being completely pressed down, said flash lamp being adapted to undergo main flash light emission each time said shutter is opened without any preliminary flash light emission;
