Nationality Scottish

Thomas Rodger was a pupil and laboratory assistant to John Adamson. On the death of Robert Adamson, John Adamson urged the sixteen-year-old Rodger to set up his own studio in the city. He had a precise approach to the chemistry of photography which earned him success at exhibitions and competitions around Scotland. Having begun as a 'calotypist' in 1848, he later moved on to the collodion process. Sadly, his glass negatives were smashed when, after his death, his studio closed down in the early 1900s.

Glossary terms
