I calibrate every two weeks with a Pantone Huey. Its totally necessary to have a good baseline. I have had to rescan a few sets because they looked great until I recalibrated
Color is tricky because everything can look great but one small range of color can be off. Like say the skin tones are really too red. Everything else can be perfect. Fucking vista was a bitch to get in sync with all the different apps too. Pics would look perfect in Photoshop and whacked in Lightroom. Solved the problem but it took some figuring out. Guess you don't have that problem now Dean
