An 18 percent gray card is a great tool for both amateur and professional photographers. The card is painted a specific shade of gray that reflects 18 percent of the light that reaches it. Because a camera does not see in color, this is perfect for adjusting a camera's light meter. This adjustment helps prevent over- and under-exposed film. Some experience with the camera's settings and options is helpful.

Instructions

    1

    Set the camera to manual mode. If the camera is in automatic mode, it will adjust the white balance itself even after it is changed.

    2

    Position the gray card in front of the subject being photographed. Have a model or assistant hold the card so that it is vertical. A leaning card will cause problems with the white balance.

    3

    Take a picture of the card. The card does not need to fill the picture, but it should take up a substantial portion. If the camera is a film camera, this picture will act as a color correction reference for the film developer. If the camera is a digital camera, continue to the next step.

    4

    Press the "Play" button on the camera to view the picture.

    5

    Open the settings menu, and select the option for editing white balance. Refer to the camera's instruction manual if necessary.

    6

    Position the white balance eyedropper over the gray card. Select the apply option. If the camera uses a stylus and touchscreen combination, touch the gray card with the stylus.

    7

    Save the setting.
