Didn't know I could do this with my XTi

What type of lighting would be best suited for an application such as this? Maybe a lens light?

I'd be expecting to get some glare from the shinier papers because the ringlight is right on the lens axis. Two lights at 45-degrees are best. In a pinch, light from a window on the shady side of a house will work, but you'll have to check exposure & WB each time you use it.
One light from more than 10' away might be even enough, too.
