Thanks for the images, and also for the heads-up on Luminance HDR and Picturenaut. I was looking for an alternative to HDRShop.

Bagginsbill shows how to make IBL probe images from a scene within Poser here: https://sites.google.com/site/bagginsbill/free-stuff/genibl---ibl-generator

Just to add:- I couldn't manage to add the "Well in the Town" image to my cart. I notice the button doesn't have a cart symbol on it as all the others do.

Also, I may have accidentally ordered twice since I thought the confirmation code hadn't worked. Apologies for that. :)
