This is a photo of one of the Ferris Wheels on the Santa Cruz boardwalk (the spinning Ferris Wheel is also shown here). I took the photo shortly before a security guard kicked me and my tripod out of the amusment park.
To create this photo, I used a polarizer (to saturate the colors) and a neutral density filter (to lengthen the exposure time). I like the way the evening ocean mist softens the edges of the spinning wheel.
[Nikon D300, 18-200mm VR Zoom lens at 18mm (27mm in 35mm terms), circular polarizer plus 2X neutral density filter, 1.3 seconds at f/29 and ISO 100, tripod mounted.]
