An emulsion lift, or emulsion transfer, is a process used to remove the photographic emulsion from an instant print. The emulsion can then be transferred to another material, such as glass, wood or paper. [1] The emulsion lift technique can be performed on peel-apart film and Polaroid Originals integral film, but not on Fujifilm Instax film ...
Polaroid produces lines of black and white [6] and color film compatible with the SX-70, [22] though their films use a different chemistry than original Polaroid film and have different characteristics such as lower color quality, longer development times, and higher sensitivity to outside forces including light and pressure.

The practice that created dye diffusion transfer prints was first introduced by Edwin H. Land in 1947, who called the technique the Polaroid-Land process. These initial prints were made in sepia tone, and as chemistry progressed, true black and white prints were launched by 1950, and color prints followed in 1963. [ 2 ]
In 1947 Edwin H. Land introduced the Polaroid-Land process. [4] The first instant films produced sepia tone photos. [5] A negative sheet is exposed inside the camera, then lined up with a positive sheet and squeezed through a set of rollers which spread a reagent between the two layers, creating a developing film "sandwich".
The New55 PN system also improved over Polaroid's Type 55 by having a lower parts-count (thus less thrown away) and, in the photographic results, the New55 PN positive and negative densities were identical (where the Polaroid Type 55's were a stop or two apart, forcing the sacrifice of either the positive or the negative in order to gain ideal ...
A building seen through polaroid sunglasses. This material, known as J-sheet, was later replaced by the improved H-sheet Polaroid, invented in 1938 by Land. H-sheet is a polyvinyl alcohol (PVA) polymer impregnated with iodine. During manufacture, the PVA polymer chains are stretched such that they form an array of aligned, linear molecules in ...
The assembly was equally innovative, with lead not merely holding the glass in place but defining the image and creating linear effects. Furthermore, his layering of glass creates dazzling depths and color effects. "Awake Thou That Sleepest. Arise from the Dead and Christ Shall Give Thee Light" from Ephesians 5:14 is inscribed on the window. [3]
Came glasswork includes assembling pieces of cut and possibly painted glass using came sections. The joints where the came meet are soldered to bind the sections. When all of the glass pieces have been put within came and a border put around the entire work, pieces are cemented and supported as needed. [1]
