In Stereo with Geoffrey Berliner and Lisa Elmaleh November 22&23

from Erica Criss

Penumbra Foundation | Center for Alternative Photography
November 22&23 10am-6pm

In this workshop, students will learn how to create glass negatives and stereo tintype portraits using the wet plate collodion process.
Stereoscopy, better known as 3D imaging, was all the rage in the mid 19th century. (After all, what other entertainment did they have? There were no movies, radio, television, smart phones, etc.) Stereo pictures are taken by means of a camera with two lenses. This provides two separate images made with two separate lenses that have slightly different perspectives. Although the pictures appear the same, they are not. When looked at in a viewer, which has prismatic lenses, your eyes will blend the two views into one and the brain perceives it in three dimensions.

Day one of the workshop will focus on the techniques of wet plate. Students will learn how to mix chemistry, pour collodion, expose, develop, fix, and varnish their plates. Students will be using 5×7 cameras equipped with antique brass stereo lenses. All cameras, chemicals and materials will be supplied.

The second day of this workshop will be dedicated to printing the stereoscopic glass negatives in the darkroom using gelatin silver methods, mounting them on board, and viewing the created images through plastic viewers.

The tintypes and wet plate negatives will be scanned so that digital media can be produced from these images. Each student will leave with a stereo tintype, a glass negative, and a gelatin silver print mounted for 3D viewing. Students will also receive a stereo viewer to enable proper 3D viewing of his or her stereo views. (from )
