Special Techniques of Photography

The collection has a number of rare and precious pieces from early years of photography which were made with special processes. These include daguerreotypes (single positive photographs on silvered copper plates) in cases, frames or jewellery; talbotypes (prints copied from paper negatives onto salted paper); ambrotypes (collodion wet-plate negatives converted to positive images by a black black); and ferrotypes (positive images on iron plates). Pictures applied to some other materials - silk, canvas, leather, parchment, porcelain, glass - can also found in the collection.

We keep beautiful representatives of 19th century painted photographies; two-layered, colored chromotypies resembling color photos and the color photo experiments of Ferenc Veress from Kolozsvár.
