Shifting the black-point away from 0% luminocity before encoding to 8-bit h.264 enables the camera to suck additional low-light color information out of the sensor.
It is the lowest 5% that are being boosted in VisionTech so that actual color information (H,S) is preserved where it would otherwise be lost due to luminocity values of 0-2. With our picture styles we have seperated the luma range into 20 increments of 5%.
To explain, the internal processing of the picture styles employ the HSL standard which stands for Hue, Saturation and Luminocity. (3% or RGB 9,9,9)ĭespite popular belief this is not because it gives more latitude (which it doesn't) but to enable the camera to encode color information where in other profiles there would be none. VisionColor utilizes the entire tonal range available in the 8-bit coding space, clipping at 0 and 100% luminocity (RGB values of 0,0,0 and 255,255,255) whereas VisionTech performs a slight boost of the blackpoint.
