Pictures reddish or orange
Although normal room lights (tungsten lights) appear white to our eyes, their light is actually much "warmer" than daylight, giving a reddish or orange color to pictures. This happens with digital and film cameras. To prevent or lessen this reddish or orange color:
If your digital camera has a selectable White Balance mode (check your camera's User's Guide) and you are not using the camera or external flash, set the White Balance mode for "Tungsten" light.
If your pictures are reddish even when you use the camera flash or external flash, the room lighting is overpowering the flash. Try setting the White Balance mode for "Tungsten" and continue to use the flash.
If your camera does not have a selectable White Balance mode, use the camera flash or external flash when taking pictures in lighting that makes your pictures turn out reddish or orange.
If you can, turn down or turn off one of the room lights (without making the room too dark), or move your subject so that it is not being hit directly by the room lights.
If you can, when taking pictures in the daytime, try opening any drapes that might be covering windows. Letting in natural daylight improves the color quality of the lighting.
