How to get this fade in and unmask effect?

I’m trying to learn these fade in on load and unmasking effects shown on:

  1. I am able to fade the movie clip in, however not sure how to get that bright white to fade effect.

Here’s what I have for the fade in:

onClipEvent (load) {
//Set movie clip lady alpha to 0%
_root.lady._alpha = 0;
onClipEvent (enterFrame) {
//Fade movie clip lady in
_root.lady._alpha += 3;
2. For the navigation that unmasks itself once the movie clip fade in, I am clueless on where to start. Any ideas?

Thanks Macro.
