Why You Should Set a Custom White Balance?
Setting a Custom White Balance before you begin shooting remains the most reliable way to consistently reproduce accurate, balanced color in digital cameras.
Even the best digital cameras struggle with consistently reproducing accurate color. Images shot with inconsistent or incorrect white balance settings may appear unnaturally warm with too much yellow, or too cool with a cyan tint. Anyone who has wasted time color correcting images knows that fixing the color temperature and tint of photos or video can be a frustratingly difficult and time consuming process.
When not in use, the ExpoDisc is small enough, and tough enough to simply carry around in your pocket.
