Camera set to fixed focus (otherwise it won't shoot if it can't find a focus point, which is really annoying), and a shutter speed/aperture/ISO combination which would allow a longish shutter speed. Shot whilst holding the camera in front of me and walking along. This is a lovely wooded path - the trees arch completely overhead. To the left is the road, to the right, the park.
This is real abstract. The patterned waviness of the lines makes it look like it was shot through the type glass used on a shower door, but there's enough detail to differentiate between the trees and the walkway. Nice shot.
