Here's a bit on the process ...
For this image, I used my D700 with the 70-200VR at 120MM on a tripod next to a swiftly moving brook and took 5 frames at 0EV, -2EV, -1EV, +1EV, +2EV. I shot Aperture Priority at F/16 and the 0EV exposure was 4 sec. The light was sideways and very warm. The 0EV turned out to be very overexposed and the best exposure was the -2EV. Normally, I try to be more careful with my exposures and shoot in manual, but I was in a rush as I was losing the light.
When I was reviewing my images, this one caught my eye as it reminded me of something I had shot a long time ago - so I decided to make a go of the HDR.
I did more processing on these RAW files prior to the TIFF to HDR conversion than I normally do - I used a graduated filter, crushed the Blacks, cropped to 4x5, boosted saturation ... etc. I ended up sending the 0EV, -2EV and -1EV to Photomatix for conversion.
Here they are as they were sent to Photomatix:
Following the conversion using the Details Enhancer, I flipped the image along the vertical axis and did some minor global image enhancements in PS.
Happy to share any other details ...
