I am currently helping to put together a website for an Artist, who paints to Canvas. They would like to create Printed Copies of their Painted Canvas work.

The only way I can think of achieving this, is by either Scanning the Painted Canvas or taking a Photograph as to generate a Digital Copy of the Painting. If taking a Photograph is a viable option, is anyone able to point me in the right direction of how best to approach this? For example; Is there a specific Camera/Lens, do I need certain settings on a Camera, would I need to take a Photograph and then edit it in Photoshop?

I am not a Photographer myself, so any pointers on this matter would be greatly appreciated.
