Hi
There was an article in August issue of DCW titled 'Slam Dunk a Stem". I have tried the project a few times using a fish tank and one Mettle 400 studio light. All my shots come out blurred. Has anyone else here tried that project and could kindly give some pointers on how they did it please.
On most shots my settings were:
ISO 100, f/8 at 1/250 sec. Camera (Canon 7D) was set on a tripod and I used a remote to trigger the shutter.
Thank you.
