Abstract
For developing residual-moisture photographs according to the wet-film technique, a pre-treatment with a first solution of about 5% ethanolic NaOH is performed first at about 13.degree. C. After the alkali exchange, the exposed film passes through a bath at a bath temperature of 50.degree. C. with a hydroquinone-containing photographic developer. This 'Two-bath wet developing method' takes place in daylight. The developed, fixed, rinsed and dried film can be evaluated directly.
