This review is from: ExpoDisc EXPOD2-77 2.0 Professional White Balance Filter 77 mm, 82mm (Black) (Electronics)
Poperly used, the ExpoDisc has provided easy and excellent white balance and colors. It is important to follow the directions though; namely to shoot the WB shot from the position of the subject, if possible.
Overall, this product is a fantastic "life hack" for photographers, especially in difficult light situations. Don't roll the dice with automatic white balance, and don't burden yourself in post; just skip to the right answer with the ExpoDisc 2.0!
