An alternative to standard ambrotype developers using acetic acid designed especially to maximize the contrast of resulting images.
The Ambrotype Developer No3 enables the photographer to achieve extreme contrast, much higher than most available developers, as well as brighter, more pronounced whites. The concentrate should be mixed with deionized water at a ratio of 1:2 prior to use. The 3 litres of resulting working solution will be sufficient to process 300-400 5x7 inch plates (depending on the developing method).
A bottle of 1000ml.
