Monitor calibration and gamma. I printed my first photos via the Minolta Dimage 5400 through Photoshop and then Canon i9900. Thought I did job on color calibration, but the printout was way more washed out than the screen.
Sigh. The above is a good site that explains how to do color calibration. I thought I did it correctly with the Adobe Gamma tool, but I guess I need to read more. Or spend $150 to get a piece of hardware that does color calibration. This spits out a custom ICC that corrects for a particular monitor.
