A versatile toner for producing a variety of brown tone effects, this 100mL bottle of MT2 Carbon Toner from Moersch Photochemie is ideally suited for warm tone papers and those with high silver chloride content, however can also be used indirectly with neutral and cool tone papers. The image tone can be adjusted from a cold brown to a warm brown by increasing the toning time and adjusting the dilution between 1:30 and 1:200, with longer processing times resulting in the warmest results. The toner, when mixed at 1:10, can be stored for up to two weeks in a tightly-capped full bottle, or up to two days if stored at a dilution of 1:200.
