I was asked to a bit of grinding today, which I really enjoy. After I'd finished, I asked my dad to grind a bit so I could take a photo of the sparks flying. I experimented with the angles, and found that the low angle as shown in this photo works the best.
This photo was taken on Tuesday 14th August 2007 at 5:04:40 PM, with an exposure time of 1/20 of a second and a f-number of 2.9.
