The exponential growth of high-detail photographic reproduction over the last century is premised on the minute half-tone dot, which is also the fore-bearer of the contemporary digital pixel. Upendrakishore Raychowdhury was an internationally recognised pioneer in the field and is credited with inventing one of the key components of the half-tone process.
Between 1897 and 1912, he wrote nine essays on aspects of his half-tone technique for Penrose’s Pictorial Annual, a London-based periodical of the graphic arts.
This edition brings together the essays for the first time, and in facsimile.
