"Excellent pictures! I'd be interested to know your post-processing techniques."
1. I shoot RAW.
2. No, none of these images are HDR. You are looking at what has been extracted from the camera's normal image data in a single shot.
3. Post-processing.
a. They get imported as RAW into Sigma Photo Pro with minor adjustments made to the RAW files to correct white balance and exposure. Then they go to Photoshop, where:
b. I'll add a curves adjustment layer and correct curves for the black and white points only. On some occasions I will put an inflection point in the curve and adjust accordingly.
c. I may use one or more of: gradient layers, photo filters, lab color, shadow layer, but only if needed and only if it doesn't screw up the colors. I don't like artificial color imparted in the images.
d. I then resize the image to the medium for which it's going to be delivered, create an Unsharp Mask to apply sharpening, then Fade Sharpening, but only on the luminosity channel, which gets rid of some of the ghosting around the bright areas of the image that were sharpened.
