You can take a light negative and intensify it to the density that is required for albumen printing or Pt/Pd what ever suits you. When shooting for a negative you would double or even triple your exposure time as compared to an ambrotype. You then would develop three times longer than your development time for an ambrotype. At least this is how Coffer taught me. Even then you may need to intensify the negative to build enough density. Sometimes you nail right without intensification.
