Can you really make a White Balance disk out of coffee filter paper? You know, instead of using the ExpoDisk you make one out for yourselfâ€¦
Jason Wallace swears by his invention, the CoffeeFilterDisk. He says it achieves a similar effect as using an ExpoDisk, which could cost you anywhere from $70 to $170.
Jason cuts out a circular piece of the coffee filter paper, sticks it onto any old UV filter lying around, and presto! He has an ExpoDisk copycat.
You use it like you would an ExpoDisk, says Jason W., â€œyou stand in place of your subject to be photographed, and point the camera TOWARD the source of light (not toward the subject to be photographed). You then perform a manual white balance setting with your camera. After this, the camera will be properly calibrated for the light in the room.â€
