Thanks for looking and commenting. Like most of my images, this is a Tone Mapped image. I have written an article in "Tips and Techniques" which might interest you. There appears to be little (no) interest to date. Shame! If you use it, then you will never look back. Regards Stephen

White balance looks perfect and wide range of values. No pattern noise in shadows that I can see. It is something I have to be careful of on my 5D Mark II. Is this a single shot or did you do HDR with multiple frames?
