Peter, just saw your post. I know it's a late reply however if you're still trying to solve that problem I suggest checking out Radeka Photography. What you are looking to do I think is reduce contrast up to a degree you find appropriate thereby opening up the shadows, however, you then would probably want to bump the deeper values (to your taste) back down. The initial CRM will reduce contrast but the SCIM (shadow contrast increase mask) will then push the "lower end" of the values you just raised back down. The net effect is opening up the shadows. Hope this isn't too confusing. Give lynn a call.
