No longer a newbie, moving up!
Are you serious?? If so HDR means High Dynamic Range. This is actually a fairly new deal for me as well but it really means to take multiple images of a scene with varying light levels and contrast ranges and combining them to make one image. So for exmple if you have a sunset scene with a dark foreground and the bright sky behind you can take a shot exposed for the foreground and one for the background and combine these to make a better image. Now that is a synopsis from a total HDR noob so if anyone has any more input bring it on.
