How could I achieve this!?

Hi there!

This site has some really fantastic tutorials and Im certain I have come to the right place. I really need help in achieving three things, the first one is the transition effect created on this site: www.kurdmaverick.com Upon clicking a menu button this graphic transition occurs, how to get that? I’ve tried masking but it just looks horrible.

The next is a photo gallery, I really want to know how to create something like this:

And lastly, how to achieve such crisp looking images as featured in the gallery above!!

I will be truly greatful for you help!

Thanking you in advance,
Ro
