The Calibrite ColourChecker White Balance is an 8.5 x 11 inch-sized target for delivering accurate tonal response in a broad range of lighting conditions. It provides the needed standard for comparing, measuring, and analysing differences in the white balance inherent in various processes, such digital camera sensors with customisable colour profiles. As lighting conditions change, your camera shifts the way it reproduces white, resulting in colour shifts in your photos or video footage. ColourChecker White Balance also gives you a way to adjust your digital camera’s colour sensitivity to exactly match the ambient lighting conditions. Setting a custom white balance for each lighting situation will make the previews on your camera’s built-in display more colour correct, make your histograms more reliable, and speed up post-production colour editing. Raw shooters can capture anytime during the session to gain these benefits, while JPEG shooters should make it your first shot.Why can't I use just any white object? White balancing on a piece of paper or other gray elements in the scene may seem like a simple workaround, but most objects are not actually neutral under all lighting conditions, and they're certainly not consistent. An inaccurate white balance will result in color casts and a lack of consistency between lighting conditions.
