The calibration also compensates for the image brightness and contrast, variations in the computer's video hardware and the ambient light conditions in the room where the monitor is situated. The ambient light conditions make a big difference to the overall calibration. Calibration made a huge difference to my printed work, and as I don't own a printer I always use a print service. -- -bmw -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
