Designed to produce a distinct warm, brownish image tone, this 1L bottle of SE1 Sepia Paper Developer from Moersch Photochemie is a unique developer for fiber based and resin coated black & white papers. When used in conjunction with warm tone papers, an overall brown tone is possible, and the image tone can be adjusted depending on paper type. When working with fixed grade papers, this developer can also vary the available contrast scale depending on the working dilution. This developer is also ideal when used in conjunction with light selenium toning, from 1:100 to 1:200, in order to produce more of a sepia tone with deeper black tones, along with the ability to achieve a colder brown tone with longer toning times.
