League of Legends (LoL) Question: Camera

Up,down,left,right arrows or move mouse to the edge

Basically, when you lock your camera,before your champion was in the center of the screen and now your champion is at the edge of the screen closest to your base and it is more zoomed out. The position of your champion adapts to which side you are playing on and where on the map you are. So if you are red side bot, your champ would be in the top right edge, if you are blue side top you champion would be in the bottom left edge. and in mid it's just on the side of your base.
Hope i helped.
