Daguerreotype:
Daguerreotypes were used when commercial photography was first invented, back during the 19th century. The process included a long waiting period for the camera to take in light from the surrounding scene, then after, the photograph was printed on to a steal slate with chemicals and ink. In my photograph, I used digital techniques in order to create the same look of decay as an original print. I did this photoshop. Here's the before and after, this photo is of the Hawthorne bridge. I chose this because it reflects the time period, and I like the grunged up look I was going for.
Cyanotype:
For this more modern technique, blue ink is applied onto water color paper, and the lights show up as white highlights, and the darker the color, the more denim blue it turns out. In photoshop, I created this technique by creating a new layer, filling it white with paint bucket tool, then painted black with a grunge brush, put the layer under the first, put a lighten filter. Then I turned it B&W and added a denim blue tint. I think it turned out well.
Gum Bichromate:
For this technique, the original is just the same a a cyanotype, but with a multiple layer of ink process. This was achieved in photoshop by doing the same as the cyanotype, but adding 2 more layers of a yellow, and red. They then all together created this gum bichromate look.
