Here is the work flow on the 2 below.
1. 3 raws -1 0 +1
2. Run them through photomatix
3. play with settings in photomatix. Strength, white & black point.
4. Open them up in PS. Adjust levels, saturation, then maybe run them through smart sharpen set to lens blur. Usually I use lab color sharpen but I haven't bothered with the HDRs.
Thats pretty much how I do them all. It just takes practice my first few looked horrible and some types of photos don't work well at all with hdr. You just gotta experiment.
