Thanks Graham, I'll have to try that Autopano route, never thought of using it that way.

Autopano HDR
 

Andy,Yes, Autopano makes a very credible job of HDR; no over-enhanced "Van Gogh on acid" results of course, but that suits me.

One thing that I have found is that the selection of 'colour HDR' in the editing phase HAS to be the first command; otherwise it can cause a program crash. However if you have a recent version (I have insufficient memory to run the latest) it may not apply.
