Diaphoto glaze, range 31
Like photography itself, retouching is renown for its vivid history. Only a few years after the black-and-white argentiferous photography had been established (the 1860s), the idea of colouring the images manually has been implemented. The aniline colour, too, was introduced in those years. This dye, suited for the then popular albumen prints, was even more adaptive for the gelatine emulsion prints that were developed later.
Thus it came in the 1980s that these watery colours completely replaced the oil-paint and watercolours in the retouching technique. The Diaphoto glaze consist of dyes solved in water. As the dyes are highly concentrated, the colour can be diluted to an infinite number of shades. The colour itself has a lower lightfastness than airbrush colours.
Available in the following sizes:
