I've decided to give this a nickname. Every time I go up the hill, this piece of dead tree is in a different position. It's either the lambs that are playing with it or a walker moving it. :-)
I was asked how I got the light on the tree and the grass. It's actually all natural light and a combination of a polariser (CPL) and a ND Grad filter. Let me explain...in 1990 I used to work as an Engineer in the Semiconductor industry, so I had to understand an awful lot about light and physics. Part of my job was using light sources to spot dust particles on silicon wafers. One method was polarisation. This is along with many things is what I adopted into my photography.
In photography, the polariser is almost exclusively used to darken skies and cut out reflections. For example, if you turn your polariser slowly, you will see the reflections disappearing and the sky going dark. If you turn it the opposite way, it can make reflections and surfaces appear brighter - which is what people don't want.
However, you can use this unwanted effect to your advantage in landscape photography as follows:
1. Set up your composition.
2. Drop in an ND Grad and check the compo, light etc.
3. Drop in a CPL and turn the filter to maximise the foreground reflections.
I'm sure the technique is nothing new but it's how I first learned how to use it 20 odd years ago.
