Here are some interesting links.
The Calotype Society - introducing my fellow 21st century Calotypists.
Larry Schaaf's weekly blog.
Mat McCosh - he used to make Calotypes , but turned to Collodion in dispair. Nevertheless his work on glass is atmospheric and very fine indeed.
If you love the work of Robert Adamson and David Octavius Hill then this is a treat.
Fiction writer and St Andrews graduate Ali Bacon brings her own words to the calotypes of Hill and Adamson and lends a voice to those who sat for them. I heard a reading by Ali at the photographic Festival in St Andrews during September (2016) and this lady has talent .
Richard Alton is a very fine and insightful photographer with a unique eye for animal photography . Mainly shooting Kodak Tri x 400 film with his trusty Leica camera . Currently living in Zambia he writes a weekly blog which introduced me to the Photography of Saul Leiter . For which I am eternally greatful.
