Printing out Paper expert Siegfried Rempel will give a lecture on this fascinating process on Friday, March 24. Join us for this special opportunity to learn more about this historic method – the lecture is free and open to the public. If you’re feeling inspired, join us for our Printing out Paper Workshop the following day! Learn more and register here.
Printing out Paper, or PoP, makes an image by exposing a negative and paper to light without any chemical development. With a printing-out process, you can watch your image come to life during your exposure, rather than having to wait until it is processed! Used originally as a simplified field process without the need of a darkroom, today we use this handmade emulsion to create artful images with subtle and warm tonality.
The use of Collodion in photography for the production of photographic prints an be found as early as the 1850s, and is most commonly used in the Wet Plate Collodion process to produce tintypes and ambrotypes. The concept of an “emulsion” of silver salts in a collodion binder was introduced by Gaudin in 1853 and by 1861 he was actively producing the “Photogene” collodion emulsion.
The collodio-chloride print has a similar physical appearance to its gelatin counterparts and it can be difficult to tell them apart. In fact, modern gelatin silver darkroom papers evolved from this early printing method! Today, we still practice the collodio-chloride process because of the rich and beautiful tonality it imparts on our images.
