Just messin' around with the camera this evening.  I took photos of the three guitars separately, then stitched them together.  Each guitar was lit differently, so different camera settings on each shot.  Aria electric - 0.5sec, f4.0, iso400.  White Fender - 1.3sec, f4.0, iso400.  Acoustic - 30 seconds, f5.6, iso1600.
