I have used others with varying personalities and web site ease, but in the end the product it's self is what I will be living with.
The Backdrop Warehouse product is absolutely the best in the field IMO. You will be working with a photographic artist. This is more of a process than a simple transaction. He wants the same as you, the very best application for the your layout
The focus, the prospective, the coloring, the even perpendicular subject (NOT just a panarama camera shot!) very high quality paper. No matter where you stand the view is straight ahead not the edge of a panned shot.
I creased/ wrinkled one section and it came out perfectly flat upon mounting. The "paper" has more of a cloth feel to it.
Yes the web site is involved but so is the product offering. He has a wide variety of product line enough for any budget. He even gives a rebate when you send in finished photos of your installation.
Matching from panel to panel is very even.
If you want a high quality finished product that will sweep you off your feet, spend some time on the site.
It is very difficult to use words to properly convey what a wall of Backdrop Warehouse will do for your RR.
The product is so high quality that you can install the top and bottom edges with Velcro and rubber cement the seams for easy removal and reuse on another layout. Nothing else comes close IMO.
Challenge your self to invest some time and patience on the website.
