Cuban born, Clatonia Joaquin Dorticus of Newton, New Jersey invented an improved photographic print and negative wash machine (see patent drawing to right). During the process of developing a photographic print or negative, the product is soaked in several chemical baths. The print wash neutralizes the chemicals in each bath process, so that the time the chemicals effect a print can be exactly controlled. Clatonia Joaquin Dorticus believed his method would eliminate over washing that could soften the photograph too much.

Clatonia Joaquin Dorticus - Photo EmbosserClatonia Joaquin Dorticus also invented an improved machine for embossing photographs (see patent drawing left). His machine was designed to both/either mount or emboss a photographic print. Embossing is a method or raising parts of a photograph for a relief or 3D look.

Clatonia Joaquin Dorticus's other inventions included an applicator for applying color liquid dyes to shoes and heels, and a hose leek stop.
