Talbot was a mathematician, physicist and philologist but is
best known for inventing the negative/positive process to
produce photographs between 1835 and 1839. For the first
time, any number of prints could be made by transferring
the negative image onto special paper to make a positive
print – the process known as the Calotype. Talbot’s The
Pencil of Nature was the first book of photographs.
