Yep, I had a Alu di-bond print done (by whitewall actually) of a landscape panorama I took in Lyme Regis. The effect is quite stunning if you hang the image in an area with a lot of natural light as it has a kind of glow. The image overall was darker than I would have liked, but that was likely due to a callibration issue between my monitor and their process (there is no print profile for alu!). My only issue was that in transit when we moved house, at some point a smal scratch has appeared and as such the piece is ruined - quite expensive to just discard :(
If you are looking for that particular effect then it is a nice way to go for the right image (dramatic landscapes, architecture etc), but if you are just looking for something that will last the course of time then a giclee print on archive quality paper will last 100 years plus.
