An outstanding blog for those who have interest in photogravure techniques, by expert photographer and researcher Carles Mitjà. Carles is doing traditional photogravures, although he is innovating the process by using digital techniques for a scientific study of the process.
“Photogravure was part of the early attempts made in the discovery of photography. Several previous experiments had been performed by Nicéphore Niépce and Henry Fox Talbot derived from the pre-existing gravure and etching techniques. Finally, after the first negative-positive systems appeared and responding to a problem with the permanence of his paper positives (Schaaf, 2003), Henry Fox Talbot patented the first photogravure method in 1852. Many years later, in 1879, the photographer and engraver Karel Klic modified the early Talbot method taking advantage of Joseph Swan’s and Louis de Poitevoin’s technique for the so-called carbon printing method. Klic’s decisive contributions were the aquatint grain on the copper plate and the use of gelatinised paper sensitised with potassium or ammonium bichromate, known as the carbon tissue. The result was called the Talbot-Klic method.”
