Thanks Marc. I'm pleased you like it. I take 5 different exposures and hope the clouds stay still. I got lucky this day. I use Photomatix to do my tonal mapping. I experiment with the tonal values until I have it just right. Sometimes it can take a while. I then save my settings incase they come in handy on another shot for later...very important to save your successful settings....
I then take the image to Photoshop and work on bringing up any flat tonal areas or patch fixes if needed. I find HDR work flattens most images tonally so need to be worked a bit in Photoshop or whatever software you use. I find it takes a lot of fiddling around to find what "you" like. I like Photomatix because it does "not" do the work for you... like Topaz does...and you can develop your own skill set. I look forward to seeing a shot you have done. Hope this helps.
