Negative Positive
Title: ExpoDisc
Review: I bought the ExpoDisc on the recommendation of a friend who is also a professional photographer. I have been using a SmartShooter Balancesmarter 20" target. This device works well but it requires that you unzip, unfold and hand the target to your subject. Then, after taking a picture of the target, it is refolded, put in its case and zipped up. The Expodisc on the other hand, is very easy to use. It fits on the front of you lens. Then depending on the lighting conditions, you go to where your subject is and either aim the camera back to where you will take the picture from or toward the main light source. Turn the auto focus on your lens off for a moment(so the camera will take a picture without focusing), take a picture for the custom white balance, then go and take great pictures.
