You mean to see the dark areas?
I often use the Fast Color Corrector and adjust the Input levels.
and how do you do that plese im using a mac and a novice x
You go to the effects panel. Then you select the effect named "fast color corrector" then adjust the input levels like Jim suggested. You can drag the effect on top of the clip you have inside the timeline. Then you can adjust those controls inside the "effect controls" panel/window.
You can just simply drag the slider.
I'd highly recommend you invest in purchasing a lynda.com membership if you intend to continue editing. They have extremely helpful tutorials for people who truly want to learn Premiere along with all the other adobe programs as well. You can also find good help by watching a lot of the free adobe tutorials as well. Lynda.com also offers SOME free videos however to get to watch all their videos you have to sign up and become a member.
