How to Fix WB In-Camera With a Grey Card

The exact way of setting the white balance in camera with a grey card might differ from below, depending on the manufacturers.

Check your camera manual or search on Google about custom white balance and specify your camera’s model.

  • Place the grey card in the scene;

  • Set the camera to manual focus;

  • Frame the shot so that the grey card fills the whole frame. Don’t worry about the sharpness of the image. It will work fine even if it’s out of focus;

  • Check exposure and adjust if you need to;

  • Press the WB button while turning the main dial until you select PRE.

  • Release the button. Press and hold it again until the letters PRE start flashing.

  • Take the photo of the grey card before PRE stops flashing.

  • That´s all! The camera has just created a WB preset based on the photo you just took.

In other camera models, you might need to take a photo of the grey card and then select it in the Custom White Balance as the reference image.
