Yeah Mike, I understand the benefit of HDR processing for multiple shots so you can capture the HDR in the first place. No question about the procedure for that.
My question was purely relating to using the one raw image to create to images which you then blend. The raw image has all the data that you have to play with, and the Shadows/Highlights adjustment in PS CS2 lets you do exactly what you appear to be doing by splitting the image and using the HDR blending.
I was just wondering if you had a reason for doing it that way, or if you'd done the comparison to see if there's an advantage.
