Graffiti (Photography Tuesday)

Its Tuesday, which means that I dip into my collection of photographs and share something with you, the 5 people who accidentally clicked the link on Google/Twitter!

Today its some Graffiti on a train speeding past.

Taken with my trusty Canon EOS 5D Mark III, through an EF 24-105mm f/4L IS USM, at 105mm, ƒ/4, 1/8000s, ISO 2000.

The high speed exposure allowed me to freeze the motion of the train as it passed at 15-20 MPH, but it does show an issue with the way that the shutter works. The shutter is what's called a rolling shutter, meaning that the top of the sensor is exposed slightly before the bottom. This causes a slight skewing of vertical lines in the image in the direction of motion. Fortunately, the angle of the picture, and the relatively slow speed of the train, make the effect less noticeable.
