Zoom In For Color Correction

Really this tip applies to any close up work but it's especially handy for color correcting.

Launch System Preferences and go to Universal Access. Under the Seeing tab (are they still called tabs?) hit the Options... button under Zoom.

At the bottom of this sheet you'll see "When zoomed in, the screen image shows:" and three options. Adjust these to your liking but under it make sure "Use scroll wheel with modifier keys to zoom" is checked. The text box there is for you to choose what key(s) you want to hold down to zoom in and out with your mouse.

Now, when you're working in FCP and need to hit that specific pixel for color correcting or just to get a better view of something hold down your modifier key and scroll up with your mouse's scrolling wheel or ball and you'll zoom into your screen. Scroll or wheel the other way to zoom out.
