Hi all

Could someone tell me how to switch off the red eye reduction lamp / light that flashes on the front of the camera please?
It is really hard to photograph portraits because the light if blinding to people

anyone have any idea what I'm doing wrong here?

Thank you

red eye reduction light or AF assist light ?

To turn off the red eye (multi flashes) hold down the flash button then rotate the rear dial until its off

Hi
thanks for the reply.
Isn't it the same thing?

No it is not. Red eye reduction is a pre flash from the pop up flash. The AF assist lamp is the white light that comes on when you half press the shutter to focus. It can be turned off too. It should be in the shooting menu, I think? Just so you know, if you turn it off, there will be more of a chance of focus hunting in lower light, low contrast situations.

According to an exemplary embodiment of the present invention, a camera is provided which has a built-in flash unit and the usual automatic or manual electronic system for energizing and firing the flash unit when a picture is to be taken. The circuit for the flash unit includes the usual high voltage charging system for the capacitor that fires the flash tube, as well as the usual "ready" light which illuminates when the capacitor is sufficiently charged. This ready light is typically a neon light and is generally disposed on the back of the camera or viewable in the viewfinder to indicate when the flash circuit is ready to fire to emit a flash of light. The present invention provides a red-eye reduction lamp on or near the front of the camera and facing forward toward a subject to be photographed, and which lamp comes on (is energized) as soon as the flash circuit is charged as indicated by the ready light coming on. The red-eye reduction lamp on the front of the camera is selected to provide sufficient illumination to reduce the size of the pupil of the subject to thereby reduce or eliminate the red-eye problem. When the flash is turned off, the red-eye reduction lamp likewise goes off.

The same concepts are applicable for providing a red-eye reduction lamp on the front of a detachable flash unit, rather than on the front of the camera, such that the lamp is aimed to provide illumination toward the eyes of the subject being photographed. This can allow more compact (e.g., shorter) detachable flash units to be provided and thus enable a less bulky camera/detachable flash unit combination.

Thus, both the flash ready and a red-eye reduction lamps come on together, and are turned off together when the flash is turned off (either by manually turning off the flash or by turning off the camera, or by the auto turn off circuit of some cameras or flash units). This provides the benefit that neither the user nor the camera or flash circuitry needs to "think" about or automatically turn on and off the red-eye reduction lamp just before the flash picture is taken. The user does not need to pause partway down during the shutter depression and wait for the preflash, and the camera circuitry does not require "pause" logic (e.g., a one second delay). Thus, the red-eye reduction light is illuminated and shines the entire time while the user is composing the picture.
