Thanks for all of your great CC everyone, I will consider maybe using the Uffuzi Courtyard HDR on the next series of test images.
Although, sadly, this Blender build is so heavy that I’d have to ship with FedEx, so, even though Blender is free, S&H will have to be paid for 
Okay, that’s fine. Will you put it on a CD-ROM then?
Yeah, I can do that, but I hope it won’t scratch it!
Brilliant!
