Trin made me realize that actually, I, too, would really like to capture -dynamics- at least as much as still images. It's tricksy. I don't feel like posting text right now--maybe later.
But, so okay, since I've already revealed myself to be a shameless fangirl/geek, I'll bring BTVS into it. I was trying to find stills and images, but it wasn't really what I wanted.
Then I went onto Youtube looking for clips, and found a few, but mostly I found a lot of fan-made videos. A lot of 'em are, well, fan art; but some of them are actually quite...well, I like 'em, anyway.
