Gary Williams just asked me how I take photos when I'm out in the field. Specifically, do I ever use a tripod and/or supplemental, artificial light. Since I've been asked this before, it might be worth covering in an entry.
I don't like to go to a stream unless the sun is shining brightly. If there are clouds, I want them to be moving along, and I'll wait for the sun to return. On occasion I'll use a "ring light" flash for some photos. But I don't like the results, and for me that's a last resort on cloudy days.
Tripod? Can't do it. The insects I photograph are almost always moving around in the petri dish that I use (photos above and below), and I have to keep moving with them.
Taking the photos often takes longer than collecting the bugs.
