Before we can get to the place where we can pre-visualize the end result, we have to test the capture “system.” That means the camera and lens plus the lighting—the total system! We will look at how to do this using Adobe Camera Raw and Lightroom. A complete calibration procedure involves
Shooting a range of exposures of a known target to determine the true Exposure Index (E.I.) of the camera.
Evaluating the exposures to identify the highlight and shadow “endpoints” and thus determine the dynamic range of the camera.
Comparing the resulting colors of the ideal exposure to known target values to derive a color lookup table to compensate for the camera’s color bias.
Saving custom settings for the camera to adjust for exposure ...
