From Aug. 4 and 7, 2013. The wide angle video was taken on the first day. The close-up stuff was on the second day. It was taken with my Canon T2i with a 50mm lens with an extension tube. My usual close-up camcorder (Canon HF-M30) had stopped working. Macro video focusing is difficult with the DSLR. The auto-focus doesn't really work while filming and the shallow depth of field (only a few mm) makes manual focusing difficult when you're hovering in surge or current.
