I am surprised that they go for months and are by themselves and have to risk their lives to take a few photos and hope they turn out well. I find it interesting that they can take pictures of what they want and do what they want and they don't need to have a list of things they need to take photos of. I don't think I would do this as a career but it would be a super cool job and would see a lot of cool things with just that being your job. I wouldn't do this job just because It would be too crazy for me and I would not be able to be away from home for that long.
