Note that the nest now has a "joiner". Here's a good link to learn more about paper wasp behavior: http://www.everythingabout.net/articles/biology/animals/arthropods/insects/wasps/paper_wasp/

Different time of day - different color! (Of course adjustable in Adobe Camera Raw). Just left it with the auto settings except for reducing the exposure a bit. I'm not quite ready to spray this nest because it's just too interesting to watch. Also, I highly recommend using the manual settings with the internal flash in your Canon dslr. It's just as smart as the Canon 430ex and 580ex. Only thing is with the XT/350 you're limited to a top shutter speed of 1/200 and with the 20D, 1/250.
