LUTCalc

LUTCalc is a desktop app for generating, analyzing and previewing 1D and 3D Lookup Tables (LUTs) for video cameras that shoot log gammas.

LUTCalc understands almost all log flavors in use today, plus standard gammas such as Rec709 and manufacturer-tuned versions. LUTCalc provides detailed exposure information about any look it generates, such as the recorded levels for absolute black, a correctly exposed 18% grey card or 90% white card and others. LUTCalc includes a number of built-in test images with charts such as high contrast and low contrast, greyscale and full colour gamut along with the option to load a .png, .jpg, or .bmp.
