Leeming LUT Pro™ is the world's first unified, corrective Look Up Table ( LUT ) system for supported cameras, designed to maximise dynamic range, fix skin tones, remove unwanted colour casts and provide an accurate Rec709 starting point for further creative colour grading.
The Pro LUTs are designed for perfect Rec709 colorimetry and have a linear luma curve, with an average measured dE(2000) of less than 1, meaning they are visually indistinguishable from reality to the human eye.
Athena LUTs are a brighter version of Pro, designed around how the eye sees, while retaining the same perfect colorimetry as Pro.
