By slowing my shutter speed down to around a second, I got this image.
Its another shot of the gardens at Newstead Abbey. A waterfall and stream link the big lake and the smaller lake. It is possible to go behind the waterfall into a dark brick structure. I’ve done that numerous times, taking photos of the waterfall looking out.
When we were there in Autumn, the reeds in this shot were tall enough to block the view of the base of the waterfall.
