Wow man - just one! Such a trip and just one pic, can't believe your buddies didn't offer to snap a few more... The way I see it they owe you big time.
As mentioned in the previous post, I do have all the vid. So there is that. It's kind of hard to hand off a DSLR for someone else to use. My buds took a couple of pics with their point and shoots, only one came out that I saw. It's just the nature of what I'm shooting with. No worries. I bought the camera to make my buddies look good.
