![]() ![]() ![]() ![]() In still image and video compression schemes, chrominance data is processed separately from luminance to exploit the limited resolution of color over relative brightness perception in the human visual system. This enables the camera to encode hue and saturation information where in other profiles no such data could be encoded due to a luminance value of 0. While the VisionColor profile utilizes the entire tonal range available in the 8-bit coding space, clipping at 0 and 100% IRE (RGB 0-255) VisionTech performs a slight boost of the blackpoint to 3% IRE. Subtle adjustments in post production are key to retaining image fidelity. It is therefore recommended to shoot with camera profiles which utilize the entire 8-bit tonal range while preserving as much usable dynamic range and color information the image sensors have to offer. ![]()
