We had my son's birthday party today at the rock climbing gym. My nephew was really into the place and asked for chalk. He squeezed the ball and POOF.... lots of chalk dust came out creating this neat effect.
@eryck I don't think I had the flash on at this point. The lighting in the building really varied from place to place so I kept experimenting with it on and off.
@boogie@ericaw@stuckinoz I'm glad you liked my photo. I was a bit of a fluke. I had no idea his squeeze would be so dramatic and that I'd actually get it digitally.
