4. Capturing the Chart


Previous Section Previous Page Contents Next Page Next Section

Creating a profile begins with capturing a digital image of the test chart. Since this capture will eventually result in a profile which describes the raw behavior of the device, it is important that no other profile be part of this capture. Therefore, you must disable any ICC profile that may affect the color behavior of the device. Otherwise, you will be profiling on top of another profile — a recipe for failure.

Most capture programs (which control digital cameras and scanners) have many controls that affect the digitized image. This is especially true on higher-end devices. These controls may be called such things as gamma, brightness, contrast or curves. In theory, a profile can handle any settings you choose (as long as you are consistent), but what you may not realize is that some settings might provide better "raw material" for profile building and production image capture than others. How do you determine what settings might be best? That is what you will learn in the following pages:
