Taking the good advice of Oshyan, I tried one of his suggestions: Using Oloneo, a new program to enhance my original image 'Canyonlands'. I had reworked the vegetation a bit and increased the contrast a little and saved the image as a .tif file. Then, taking the .tif into Photoshop, I made a second adjustment darkening the sky a bit saving this second file.
I took both .tif files into Oloneo and created a HDR tone mapping image using the two .tif files. From here, I took the saved adjustments back into Photoshop and saved the image as a .jpg.
I hope you like the results. I have always tended to be a bit too conservative with post work adjustments thinking with the purest attitude. Maybe it is time to start thinking out of the box ... maybe too saturated, we'll see.
