Nighttime fountain at the Anaheim Convention Center. This was a popular spot for cosplay photos even after sunset, but I managed to catch an angle that looked deserted.
My full gallery of photos from WonderCon is up on Flickr. Most of them are just cosplay snapshots. This ended up being the only artistic shot I took that came out really well.
