The conversion program converts it to an 8-bit or 16-bit image format, converts it into a color space (sRGB if you're planning to display the images on the web or on a TV), applies the correct color curves for that color space and color temperature to convert the sensor's sensitivity scale to the color values for that color space, and deconstructs the Bayer filter data (extrapolates RGB color values to every pixel). ![]() The RAW file is simply raw sensor data (compressed), so is usually 12- or 14-bit, doesn't have a color space or color curves assigned to it, and hasn't yet decomposed the Bayer filter (which is where most of the compression comes from - the RAW data only has one color per pixel). The way it usually works is you use a RAW conversion program to convert the RAW file into another image format. That kinda defeats the purpose of having a RAW file (the exact camera sensor data the camera recorded). ![]()
