I used a safety pin to pop the balloon with my left hand. I used a cable release with my right hand to take the shot.
Enjoy and keep on photographing.
Today’s exercise requires a little bit of preparations. Get yourself a few balloons, fill them with water, hand them up with a string and photograph them while your are poking them with a needle. Here is a link with a detailed guide on how to do it. Go to http://www.digitalcameraworld.com/2013/10/15/high-speed-photography-ideas-how-to-capture-water-balloons-as-they-explode/
Instead of one I am using two strobe lights. Camera setting 55mm focal length cropped, f16, 1/20 sec. exposure time. In my other shots I increased the exposure time to freeze the action better.
Enjoy this exercise because it is a lot of fun!
PS: Don’t forget to cover up your strobe(s) and camera properly!
