I had to photograph the lab skills competition for the ‘Outreach’ portion of the web. The big problem is that most of the students are under 18 and not able to give permission to put their photos up on the web. I was thinking maybe a long shot of a lot of backs, and perhaps some close-ups of hands. Then one of the graduate student assistants suggested just blurring their faces like you see on TV. Brilliant!
I put the ISO down to 100 and shot from a tripod so there was a lot of motion blur, then added a bit more blur in Photoshop. I only needed one shot and here it is; just look at those kids scurry around the lab!
