Layer structures for various photographs

Single-layer structure, as for salted paper prints, cyanotype, platinotypes. The light-sensitive material is within the paper.

Two-layer structure, as for albumen prints, carbon prints. The light-sensitive material is in the upper emulsion layer. The lower layer is the paper.

Three-layer structure, as for gelatine and collodion printing-out papers and gelatine developing out papers. The light-sensitive material is in the upper emulsion layer. The middle layer is the baryta layer, which gives a very smooth, white surface on which the emulsion layer rests. It is opaque and hides the irregular surface of the paper fibres. The lower layer is the paper.

The structure of modern, resin-coated paper. The centre layer is the paper core. Either side of this is a layer of polyethylene. The light-sensitive gelatine emulsion is on the top. There is also a gelatine backing layer at the base.
