Hi Bob,

I've been using a SpyderPrint which does have a density option. I don't think the i1 will give you log density values directly. I just picked up a used one but haven't yet had a chance to play  with it. However, Richard Boutwell has a tool that will do the conversion for you from 21-step LAB (more specifically the L component) readings. You can download it here:
