Look for and take four photographs using curves to emphasize movement and direction.
I took this on Saturday while travelling up the escalator. I had to go up it a few times (four to be precise) before I got a shot that I was happy with - I particularly wanted the view of the office block through the window. I produced two additional exposures in RAW (+2 and -2) then adjusted levels and curves in CS3. Finally converted it to black and white then added a tonal contrast filter from Nik Color Efex Pro 3.
This image uses curves with the aid of a fisheye lens and the escalotors act as leading lines. Posted via email from in5ers's posterous
