Today's top 30 April POTD was sent in by Dennis McMillan, and demonstrates great use of a panning technique.
"The image of the race car was shot at our local race track during a vintage racer visit (West Coast Vintage Racers). I used a panning technique to shoot it using a 5d MKII and a 70-200L IS lens. It was near dusk, so I had to use a fairly slow shutter speed for that lens (1/30, and ISO 800 @ f/4). It was a great night, but this was my favorite shot of the event. I used Nik Silver Efex to convert to B&W."
