Crazy Helicopter pic!
Took this pic of my buddy hovering a R44 after my first flight in a helo. As a long time fixed wing guy, it was a pretty awesome experience. Anyway I took this pic on my iPhone which has a really slow shutter speed. The effect that came out with the rotor and the shadow is really cool. It took the three of us a good hour and half to explain why it turned out this way. Anyway, NO photoshopping of any kind has been done to this pic. So, here is the challenge for the day, explain why this pic looks like it does!

Vertical scanning by the recording sensor.
"A digital camera’s imaging element, either a CCD or CMOS sensor, is made up of pixels that are organized into horizontal lines that are then stacked to make a picture. And the camera takes the picture by reading each pixel from left to right, line by line, from top top bottom. In the end, pixel number one in the upper left corner of the frame is sampled long before pixel five million in the lower right. Sure, the whole process is usually done fast, very fast, but it’s not fast enough to keep these helicopter rotor blades from looking bent. The camera in my Clie has a particularly slow scan rate, making it easy to lean cars sideways. I took advantage of the effect for a self portrait when I wanted to blur my office in the background."
That and the Hadron Collider.
