Silver portraits:
There is an interesting development going on in photography: beautiful nineteenth-century-style portraits using special technique and a reenactment of a dark room with old-fashioned chemistry.
Collodion Wetplate portraits.
This technique from the middle of the 19th century, makes use of light-sensitive layers which are applied ‘fresh’ on an aluminum plate; the layers are directly exposed in a special ‘camera obscura’.
After an exposure time of about 6 seconds, the plate is developed in the dark room. The result is a photo–object, a bit similar to a daguerreotype.
