Photo 1-2 Photo Lithography

Photo Lithography is briefly summed up as printing an image manually. this means that you isolate certain colours and make a stencil out of the selected colours only, then you paint on the colour to a surface by hand using the stencil. this process requires you to layer the stencils in a certain order, to get the desired result. you can use this technique to print onto almost anything. it just requires you to have the stencil and the nessacary ink to print on the material.

Cyanotype is the process of making a photo by processing in iron compounds. in order to make a cynotype photo with a digital camera, you just need an inverted photo, the chemicals, and a canvas. in order to prepare the canvas, you brush the chemicals onto it and make sure your work area is dimly lit to avoid accidental exposure to light. then you put your negative ontop, and sandwich it between two pieces of glass to prevent movement. then all you need to do is expose it to UV light (such as the sun)
Daguerre, spring 1838
Dagurreotype is the earliest photo processing technique known. It involves using a polished silver plate exposed to halogen fumes, which makes the plate photosensitive. to create the image, you put the plate into the holder, and remove the opaque protecting cover, which allowed the plate to develop an invisible image. in order to make it visible, you would expose it to the fumes given off by heated mercury in a specially made development box.
