 "An **interpolated RAW file** isn't a RAW file. For some reason this simple "

 "**Linear** has two related and easily confused definitions. *Linear* can "
 "mean that the image tonality reflects the tonality in the original scene as "
 "photographed instead of being altered by the application of an S-curve or "
 "other means of changing local and global tonality. It can also mean that the "
 "gamma transfer curve of the color space is linear. An image can be *linear* "

 "**HDR** and **LDR** do not refer to the bit-depth of the image. **High "

 "a mere 5 *stops* (the average digital camera these days can easily "
 "accommodate 8 or 9 stops), can be saved as an 8-, 16-, 32-, or even 64-bit "
 "image, depending on your software, but the dynamic range of the image isn't "
 "thereby increased. Only the number of discrete steps from the brightest to "
 "the darkest tone in the image has changed. Conversely, a 22-stop scene (way "
 "beyond the capacity of a consumer-oriented digital camera without using "
 "multiple exposures) can be saved as an 8- or 16-bit image, but the resulting "
 "image will exhibit extreme banding (that is, it will display extreme banding "
 "in any given tonal range that can actually be displayed on a typical monitor "
 "at one time) because of the relatively few available discrete tonal steps "
 "from the lightest to the darkest tone in the image."

 "**In-camera produced JPEGs don't need a camera profile**: All JPEGs (or "
 "TIFFs) coming straight out of a camera (even if produced by point-and-shoots "
 "cameras that don't allow you to save a RAW file) start life inside the "
 "camera as a RAW file produced by the camera's Analog to Digital converter. "
 "If you save your images as JPEGs, then the processor inside the camera "
 "interpolates the RAW file, assigns a camera profile, translates the "
 "resulting RGB numbers to a working space (usually **sRGB** but sometimes you "
 "can choose **AdobeRGB**, depending on the camera), does the JPEG "
 "compression, and stores the JPEG file on your camera card. So JPEGs (or "
 "TIFFs) from your camera don't need to be assigned a camera profile which is "
 "then translated to a working space. JPEGs from a camera are already in a "

 "**Useful mathematical information**: If you are dealing with Libraw's linear "
 "gamma output: Mathematically speaking, when doing a gamma transform you "
 "normalize (that is, divide by 256 if you are working with 8-bit values) the "
 "RGB numbers and raise the resulting numbers to an appropriate power "
 "depending on the respective gammas of the starting and ending color space, "
 "then re-normalize the results to a new set of RGB numbers. It's not hard, "
 "and very instructive, to do this with a calculator for a few sets of RGB "
 "numbers spaced from (0,0,0) to (255,255,255) to see how RGB numbers change "
 "from one gamma encoding to another. Lcms does this for you when you ask Lcms "
