I was waiting for some visitors at the airport. At SeaTac, you stand at the top of the escalator waiting for people to come out from the shuttle station. I was starting at the escalator for quite some time and decided to see just how slow a shot I could take with the cellphone. Using ProShot, I have a lot of shutter speed control but the brightness does eventually overwhelm things a bit. However, it was still possible to play with some interesting effects with the steps blurring out along with anyone standing on them!
