Hello, I recently purchased an NX2000 and am I having a little bit of trouble figuring out the different settings. I want to photograph my child in front of a Christmas Tree and am not sure what kind of lighting I should have (ie: should I shoot in the dark with just the tree lights on? Or should I photograph with the tree lights and natural light coming through?) I also don't know what settings the camera should be on to get the best results. Please help!!! Any advise is greatly appreciated!
