The Rainbow Flash Wizard is an accessory for photography that allows you to change the color of the light that is produced by your flash. After all, why only use white light when colors are captured by your camera. Taking pictures with a regular flash can make for disappointing results, where colors get washed out and people look sick. With the Rainbow Flash Wizard, you chose exactly the color you want, in no time. You do that by sliding (to chose the Hue) or turning a button (to tune the saturation) as described below.
Because you probably also want to visualize the actual color of the light that will be produced beforehand, we’ve put some screens on the side that display 1) the actual color, 2) the hue (i.e. the color always fully-saturated) and 3) an indicator of the level of saturation.
And that’s it ! You fit the head of your flash into the cavity of the Rainbow Flash Wizard, you turn it on, chose the color, and take pictures. Of course you may want to try different colors. It’s so fast and easy, you will probably have done it before your flash is ready to take another picture.
