How learn camera moves of this video on after effects

Hey guys! i always wanted to know how can i learn those kind of camera moves on this first 30 seconds from this video: https://www.youtube.com/watch?v=iwsMiMBjCKc
Someone can give me a light how can i make those moves? slowly going in, out, and sideways, going sideways and leaving everything behind like im changing to a new scene, someone have a clue? 
i will search some tutorials on youtube but if i could have a head start here would be really great! 
thanks!!!
