in premiere go under window and change your workspace to color correction.
you now have three monitors, in the bottom monitor click the little menu list in the top right corner and choose yv wave form. then you get your two monitors up top for source and corrected.
apply effects like brightness and contrast, colour balance, curves or maybe even tint.
for the yv waveform. you want that blue shit to be in between 10 and 100. long story simple adjust contrast to stretch it, birghtness to shift its position.
OR if you really want to get spot on and you have photoshop follow this tutorial. but this is pretty time consuming. http://www.youtube.com/watch?v=8EutVgTck6U
