| Adobe Lightroom makes some camera specific adjustments already in ACR 4.4. It knows what camera you are using from the EXIF data associated with the digital photograph. It is close, but many users feel more can be done to get the colors to more closely match reality. This is where the MacBeth ColorChart comes in play. You have the process pretty much down. What I would need is for someone with Lightroom to photograph the colorchart (with correct white balance). In post processing in Lightroom, they would apply the K20D Base (ACR 4.4) preset (available above) and make adjustments needed in the Camera Calibration portion of the Develop Module so that screen colors (on a calibrated monitor) match the MacBeth ColorChart. Initially, this should be done at ISO 100. This would give us a good baseline on how the CMOS sensor in the K20D rendered specific colors. Since the K10D uses a CCD sensor its baseline is different so the specific adjustments for that camera will be off for the K20D. |
