Expodisc Review

The expodisc is a tool to set custom white balance on a digital camera. Basically it works just like a simple grey-card. However, it’s nicely small and good to handle. I like it very much and use it all the time! On a Nikon you hold it in front of the lense and set the white balance to pre. Then you press the WB button again (press and hold) point the camera in the direction of the light source and “take a picture” (no picture is actually taken but the white balance is recorded). You should repeat this step every hour or so to make sure that the light didn’t change inbetween shots.
