It might be a time waster for you but was an exercise for me. I hope you weren’t expecting something profound and beautifully designed. I had this itch to scratch, which was to film this crazy gizmo. Never mind that I have never used my Canon Rebel T2i for video before. Instead I skipped that basic step of using the usual EF-S 18-55mm IS II lens and went straight for the fancy macro lens. But dadburnit! Nature and the neighborhood were not cooperating. With a lawn mower, air conditioning unit, and snorting bulldogs as background noise, the recorded sound was not what I had envisioned for my experiment. So what you’re hearing is a scrappy soundtrack found online which replaces the original audio.
