]]> Secondary Color Correction - Primary color correction, or grading, is applied to the whole image. Secondary correction is applied only to selected areas of the image – the area being defined by a pattern generator (e.g. a circle or rectangle), by curved lines or derived from the object itself using chromakey techniques – or any combination of all these. This way, for example, the color of a car in a clip could be changed from say, red to green.

S-Gamut- The range of colors reproduced by the Sony F65 and F55 cameras, S-Gamut extends far beyond HDTV Rec. 709, beyond other digital motion picture cameras and even beyond the range of print film. S-Gamut is made possible by a Color Filter Array (CFA) with very high- purity dyes. Sony has released to our Alliance Partners a selection of 3D LUTs (look up tables) that will simplify grading from S-Gamut to Rec. 709 for projects that have a requirement for Rec. 709 finishing. These 3D LUTs will be available for customers to download as well.

S-Log 2- A Sony system for logarithmic grayscale encoding that captures greater exposure latitude than gamma encoding. Sony’s original S-Log curve was created for the F35 and F3 cameras and captured their full latitude: about 12 stops. With the latest F5, F55 and F65 cameras capturing 14 stops, Sony needed to revise this curve. The result is S-Log 2, which can handle the extended exposure latitude now available.

]]> Stop - A ratio of amount of light where one stop represents a x2 change – doubling or halving of the amount of light. The operating range of film and electronic light sensors, such as CCDs and CMOS, are quoted in stops. Typically, a camera’s shutter speed and the lens’s aperture setting restrict the light arriving at the sensors/film so the mid brightness of the required scene corresponds to the middle of the sensor’s or film’s sensitivity range.

]]> Up-Res – The process which increases the size, or number of pixels used to represent an image by interpolating between existing pixels to create the same image on a larger format. There is no implied change of vertical scan rate. Despite its name, the process does not increase the resolution of the image; it just spreads the same over a larger canvas. The quality of the result depends on that of the interpolation. Speed is an issue for realtime work, as good quality requires a large amount of processing – which increases with the picture area.
