Project #8 - Digital Alternative Process

Cyanotype is the process of making a photo by processing in iron compounds. in order to make a cyanotype 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 on top, 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)

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.

Chlorophyll Process This process utilizes a leafs natural ability to seek out the sun. in nature, the chlorphyll in a leaf will go to the parts of the leaf that are exposed to more sun than other parts. this process uses this in order to make a green monochrome picture appear on a leaf. the way it works is that you make a negative of a photo, then put it ontop of a leaf. in order to prevent the negative from moving, you then sandwich the negative and leaf between two pieces of glass. eventually if you leave it in the sun for long enough, the leaf will start to look like it has an image on it.
