I take one whenever I notice a vista of striking beauty. I don't think I've ever taken a combat shot, because I get too involved with the fighting.

I have over 2000 screencaps of LotRO, but I've only found about 150 good enough to share on my GamerDNA page. Back when I was in high school, someone told me that a National Geographic photographer considers themself lucky if they find one shot on a roll that's good enough to submit, let alone use. I filter based on that principle.
