L.A. design company Lumi is pioneering an innovative photographic print process through the application of its Lumi Inkodye, a product that changes color when exposed to sunlight.

With Lumi Inkodye, you can print different images and patterns onto a variety of textiles and natural materials including cotton, silk and wood. When the dye is exposed to sunlight, it changes color -- permanently -- in about 5 to 8 minutes. Available in red, blue and orange, the dye can be mixed together to create different shades, and you can also add water to make them lighter.

According to the design brand's site, Lumi Inkodye can be used to create photograms and shadow prints and used for everything from painting and dyeing to silk-screening. The website says, "We're taking photography out of the darkroom by using sunlight to make durable prints on sustainable materials."
