Hey thanks for the comment. This was taken within about 5 minutes of sunrise. Telling me the shot looks like it was taken in broad daylight really woke me up - tells me I managed to make a perfectly bland photo of a stunning vista
I am afraid that when I look at the shot I see what I saw that morning - obviously not what is displayed in the photo. In hindsite it could be that the PS HDR Blend is just smashing this with a sledge hammer.
I will take three of the exposures (sky, mountain and foreground) and do the manual blending as you suggest. Hopefully my PS skills are up to capturing what I saw that morning.
Thanks again!
