With the rising popularity of digital photography a growing number of photographers are using grey cards to ensure their photographs are properly exposed and colour corrected.
"Point and Shoot". The unique gun sight on the collapsible card allows the photographer to achieve perfect focus every shot, and because the card is an 18% grey the shot will also be perfectly exposed. All this is achieved by simply placing the card near the subject and half depressing the shutter on any digital camera, then removing the card and full depressing the shutter for the perfect shot.
"Point and Shoot" also comes with a white surface on the back to accurately white balance the camera as you go.
