How to create professional gradient background
I am trying to create a gradient like in this app:  http://itunes.apple.com/us/app/day-one/id422304217?mt=12.
On the left hand side of the window, there is a black gradient that is very pleasant to see.
I noticed it also has a rather grainy texture to it.
Is there a tutorial in doing this? Also, How do I create a shadow like on the very right of the left black bar?

Thank you!
