When you describe a "thin" negative, I presume you mean that the silver density is thin. This 
distinction is relevent when using staining developers such as Pyro and Pyrocat-HD. In such 
cases the negatives have always seemed "thin" to the eye but the CI of the negative as seen 
through processes that are U.V. sensative (e.g. platinum) is quite good.

In such negatives the stain part does not have grain.

All told, one can have negatives with quite good shadow detail, with excellent tonality, which 
in fact have quite good darkroom contrast but also scan well.
