Shot in Raw - 5 shot sweep from left to right - merge using PS6 - cropped - and a small touch using Nik HDR Efex 2 - I was looking for a sharper/crisper look - and to narrow the colour width just a little. Keeping the greens, blues, whites and a touch of brown.
Hope this helps. I try to "quick experiment" with post processing as time is a factor. So in short, most of my experimental work is ..... adjust levels first - decide if it stays as colour or B+W - then roll the dice on which plugin to use - and experiment with a few templates first, and do final adjustments last to keep it cohesive. Then save a jpg and out the door it goes. The PSD file for this was about 250MB....... huge.
