I am often asked what is the optimum way to capture a digital image of art to make a fine art reproduction on canvas or paper. If you use a camera (except a possibly a NASA camera) there is always going to be distance and atmosphere that affects the image.  Not to mention, most cameras will not create a large enough file to enlarge the size of prints.  A high resolution scanner is going to give sharper images and greater range of color.  I think the above photo gives an accurate depiction of this.  The camera image was created with an expensive Nikon D700 camera.
