Oh hey, just remembered to ask:
What is your editing system (OS and video program)? What monitor are you using? And have you calibrated it?
I strongly recommend getting a hardware calibrator like the Spyder series of devices. I thought I was pretty good at calibrating by hand until I got one and compared its results to my hand-made profile. Night-and-day difference.
If you have a monitor that defaults to super-incredibly-bright (like an iMac or other Apple monitor), you'll want to turn that down to around setting 6 (ie. six full brightness increases from the lowest setting). Otherwise, your video will look waaaay too dark when played back on just about anything else.
