In 1923, Kodak published a slim professional booklet that contained, almost as an aside, a declaration that would reshape photographic practice for the next eight decades. Buried in a technical discussion of how to make large prints from small negatives, the company stated flatly:

"Artificial light is at all times preferable to daylight because of its uniformity and because it may be used at all times."

To a modern reader, this sounds obvious — of course you'd use electric light in a darkroom. But in 1923, this was quietly radical. For decades, the standard method for making photographic enlargements involved a device pointed at a window or skylight, relying on the sun as the exposure source. Entire darkroom wings of portrait studios were designed around north-facing windows to catch soft, indirect daylight. The practice was so entrenched that many professional photographers distrusted artificial light enlargements as inferior, contending that sunlight produced subtler tonal gradations.

Kodak was not merely offering a technical tip. They were waging a campaign to redefine the entire vocabulary and workflow of professional photography. The booklet goes out of its way to replace the very word "enlargement" with a new term:

"The term 'projection print' to describe the enlarged image projected through a lens on the sensitive paper is coming to be generally used because it is associated with the more modern methods and materials."

This is corporate language engineering at its most deliberate. Kodak understood that the word "enlargement" carried baggage — it implied a blown-up photograph, with all the grain and softness that suggested. "Projection print" sounded precise, optical, scientific. It implied a process, not a compromise. And crucially, it aligned with Kodak's business interest: they were selling the Bromide papers, the projection apparatus, and the artificial light systems that made the new workflow possible.

What makes this genuinely fascinating is how thoroughly the artificial-light doctrine won, and then how completely the entire craft it enabled was forgotten. Within a decade of this booklet, virtually no serious photographer was pointing an enlarger at a window anymore. The controlled, repeatable environment of the electric darkroom became the universal standard. Dodging, burning, contrast control, split-grade printing — the full vocabulary of darkroom mastery that photographers like Ansel Adams would later codify — all depended on the stable, predictable artificial light source that Kodak was championing here.

And then digital imaging erased the darkroom entirely. The vast body of practical knowledge about optical projection printing — how the distance between lens and paper governed image size, how condensing lenses shaped light distribution, how different paper emulsions responded to different light intensities — evaporated from common practice in barely a decade. Today, the physics described in this booklet are understood by a shrinking community of fine-art film photographers and a handful of archival specialists.

There is an irony worth noting: the company that argued most forcefully for abandoning daylight in favor of controlled artificial systems was the same company that would, eighty years later, fail to make the next great transition — from chemical to digital photography — and file for bankruptcy in 2012. Kodak saw the future clearly in 1923. By 2003, it could not.
