The Digital Zone Gradient is a lightweight Photoshop plugin designed to serve as a visual reference tool, displaying both the lightness, RGB values and also the corresponding zones for specific shades of grey.

This plugin is compatible with the four primary working color spaces: sRGB, Adobe RGB 1998, Gray Gamma 2.2, and ProPhoto RGB.

The Digital Zone Gradient panel allows users to easily place anchor points anywhere within the image which then displays the corresponding zone directly on the zone scale.

With this data, the Digital Zone Gradient panel provides a clear visual indication of the corresponding zone for each anchor point, enabling precise tonal analysis and informed adjustments.
