    I have been photographing a series of finds from an archaeological dig. I've been using a simple side lighting setup , shooting the finds, in RAW, on a red card background. Each of the images were then processed in ACR adjusting the white balance with reference to a grey card taken a the beginning of the sequence. Exposure and and black point being adjusted to best show the surface details. This however alters the intensity of the red background which I wish to keep constant throughout the series. Any ideas on how this can be achieved? I'm also using CS3

    Light from both sides - or use a mirror to reflect a single light source back.

    You don't say what size these finds are, but what about one of those light tent set-ups that are dirt cheap on eBay? This one even has a pair of lights and is still dirt cheap!
