Quite a popular tree, this one! It attracts photographers from miles around for the combo of loch, tree and distant hills and it did for me, too. Quite a long exposure, this one, to get the cloud movement in the late afternoon light- 30 seconds.
Just a small disclaimer: this is a fairly small crop of the full image it looks a bit blown up in the 500px view and there's a bit of softening and a hint of artefacts - really it was intended to be a print @ about 7" by 5" max!!
