I've made prints from the same neg and the only way I could tell which
was Pt/Pd and which Kallitype was by looking on the writing on the back. I
was using a developing out method with both processes, and there were no
significant differences in tonality/tonal range.
We have speculated in the past that some 'platinum' prints in collections
may actually be kallitypes. There were several formulae published around
1900 which claimed to produce kallitypes which looked identical to
platinum.
