Nitescape (DayZ)

I did a search and couldnt find a solution. I do not know what I did but I lost the ability to move with the mouse. It is in a camera mode now. I am sure I simply hit a key and did this but cannot get it to revert back to where the mouse looks.

Thanks guys, I will give that a try.

These are awesome guys!!! So what do you guys mean by filters? I see some of the shots look bueish sorta and some look very colorful. How do you do filters? Is it some kind of mod you do for it?
