I opened my photoshop cs5 book and I choose Image Adjustments Black and white. I played with all the presets... but left it at default.
This tree in my garden is lite at night. This was shot just after a snow storm using my 18-200 lens at 90mm, f5.6 2 secs from a tripod compensated down by 2/3 stops. ISO 500 Shot in raw with a little color and exposure tweaking. Not sure what else I should have done.
