Example Input: Very easy to use. Only problem is you must remove the battery every time which takes some time. A few pics have already been taken and it keeps on taking. We went kayaking last weekend - took about 20 pictures before turning off camera. Great little camera. I would love an underwater case for it.
Example Output: Good Review
