The Digi Grey allows easy correction of the colours of digital photos without the need to have technical knowledge by the user. It is a strictly neutral grey which is traditionally used as a reference by professional photographers who require exact colours.

How to use:

During the shooting:  Take a photo of the digi grey placed near the subject under the same lighting conditions. It wil be the reference photo. After that, take your other photos without the Digi Grey.

In your graphic software use the black and white point or equivalent tool and click with the dropper on the grey of the digi grey in the reference photo.  Report the same correction on the other photos.
