kallitype การใช้

• Some processes do not have emulsions, such as platinum, cyanotype, salted paper, or kallitype.
• Patented in 1889 by W . W . J . Nicol, the Kallitype print is an iron-silver process.
• While Van dyke brown and argyrotype use ferric ammonium citrate, the light-sensitive element used for the Kallitype is ferric oxalate.
• Like the Platinotype and Cyanotype, the kallitype is a contact printing process and the printer must have a negative of equal size to print from.
• Zoghlin works in many alternative process such as orotone, Kallitype, and Cyanotype etc . His orotones from the series " Aerotones " are produced on glass and backed with 23.5 karat gold powder.

• Opalotype is one of a number of early photographic techniques now generally consigned to historical status, including ambrotype, autochrome, cyanotype, daguerrotype, ivorytype, kallitype, orotone, and alternative photographic techniques and are practised by a small number of dedicated artists.
• While the Van Dyke Brown and Argyrotype are both " printing out " processes ( with the complete image being formed during exposure ), the Kallitype is a " develop out " process that requires the print to be submerged in a developer solution to make the image visible after exposure.
