ValueChecker is designed for artists to check and analyze value structure of images, videos, and GIFs by emulating the working gray (dot gain 20%) profile found in Photoshop or Gray Gamma 1.8 in other software.
Standard grayscale filters/modes ignore how the human eye perceives brightness, leading to inaccurate results where bright colors can appear much darker than they should. This tool utilizes Rec. 709 luminance formula within a linear RGB color space to ensure the values remain perceptually accurate.
