negative vs ambrotype


negative on the left.

After  long period of time spending on troubleshooting  process for positive plates, I was able to prepare a succesfull ambrotype. I learned that main issue was to use really distiled water (3x times from chemistry laboratory) to prepare a developer, and finally to filter it before use. I’m suprised by rich tonality of an ambrotype. Until now I was sure that the tonal scale of an ambrotype is much shorter then a negative.
