I heard about this technique a while back but I haven’t had the chance to try it out yet. Luckily Ryan Connolly of Film Riot fame did a test shoot using the technique. The results are freaking spanky.
I love Film Riot with all of my black heart. They bring the crazy and fun to learning about filmmaking so if you have any interest at all in the art check out the show.
[EDIT] In case you are wondering what “Lens Whacking” is, it is slightly removing your lens from your camera body to let light in behind the actual glass. The result is those wonderful flares you see in the short.
