@rlaughy Thank you Ryan! I don't have a light source on the rock, but I did use some dodge and burn in Photoshop on the rock, so that is probably the lighting effect from that.
@swguevin Thank you Sheila! I bracketed three shots each and did HDR after the fact. The panorama is a total of 5 shots (3 each for HDR), so 15 shots total with the bracketed shots. Hope that makes sense! I don't really like using in camera HDR. I feel like I have more control in Photomatix or the Nik HDR programs.
