"A quick reading through
a catalog from E & HT Anthony, during the 1860s,
shows several enlargers, including especially the Solar (Enlarging) Camera,
which itself is largely based on a design from WHF Talbot in the 1840's.
In the mid-1850s, Gustave Le Gray made a number of
his large (30x40cm and 40x50cm) collodion views of Seascapes and of downtown
Paris as enlargements from much smaller plates.
In 1854, Woodward's Solar Camera was invented and
1858, Shives invented and patented an enlarger which used direct and condenser
lenses in lieu of sunlight."
