The Tangent Devices CP200-BK is a color grading control panel that resembles a standard 3-channel color-correction tool. This modular unit has 3 trackballs centered between 3 rotating knobs. This intuitive layout provides users with 9-axes of control; something impossible while using any standard mouse. Each trackball is accompanied by 5 buttons, which can be programmed to perform a variety of functions, including resetting the filter to default.
