Sorry for the slow response but quite busy at the moment.
Glad you like the trees. It is all done in camera, the only software involved is Lightroom where I might tweak the levels a bit.
I have been taking these shots for quite a few years now and have refined the technique. Its really about time of day, season,
weather and what you point the camera at. When selling in galleries it helps to be able to say that it is not software which can devalue the piece.
I tend to shoot my landscapes at short notice depending on the weather and work pretty much on my own. However I will bear you in mind if I get any
commissioned landscapes from people like the National Trust.
By the way nice work on your site.
There was a short video about my work on the Advocate site http://www.youtube.com/watch?v=v90dIKGcIEs
