Alternative Processes | Making Inkjet Negatives | Part I – Introduction

process, originally uploaded by brad|gillette.

While many alternative photographic processes date back to the beginning of the last century, there are a few that are still in their infancy. The advances in digital photo editing and inkjet printing have introduced us to a whole new world of hybrid processes, using both traditional film and darkroom based photography in conjunction with these new digital tools. Most notable of these processes is the creation of negatives from a digital file. These digital negatives are produced by manipulating a source image digitally, whether it is scanned film or from a digital camera, and printing it on a transparent or opaque material for contact printing in a traditional darkroom. Just about anybody can print a decent quality photo from their inkjet printer, and many of you know your way around the darkroom quite well, so it would seem that bringing the two processes together would be a simple task. This couldn’t be any farther from the truth.

Alternative Processes | Polaroid Transfers

Polaroid Transfer | 7, originally uploaded by brad|gillette.

“The Polaroid image transfer process relies on the ability of dyes in the Polaroid emulsion to migrate to an alternative receiver surface during the development process. The “normal” Polaroid process is interrupted and the “negative” is placed on another material (usually paper). The dyes that will form the image are encouraged to transfer by the use of heat and pressure. This process was accidentally discovered when a Polaroid negative was left sitting on a lab counter, according to legend!”

Alternative Processes | Sabatier

Alternative Processes | Sabatier, originally uploaded by brad|gillette.

The Sabatier process is often mistakenly referred to as “solarization.” In actuality, these are both distinctly different processes. Solarization occurs while the film is still in the camera. It results when film is overexposed to the point that the silver halide crystals have been completely saturated with light, which means it has reached “gamma infinity”. When this occurs, the crystals with the most exposure begin to reverse themselves. A good example of this is in a print where while everything else appears normal, the sun is a deep black. The Sabatier process however, is done entirely during the printing stage, with no special exposure of the film necessary. In the simplest of terms, it is when you re-expose the paper with light halfway through the development process. This results in the darker areas of the final print being rendered as normal, while the lighter areas are reversed.
