I've been wanting to try out both techniques for a while so on my wander round Vancouver's Stanley Park I found this fairly uninteresting water outlet and took three shots at different exposure levels and times. Processed all these in Photomatix, and didn't really tinker around with the settings too much. The composition isn't great and there's quite a bit of over-exposure in the bottom left but I was happy with how the water turned out at least!
