Whats is a Daguerreotype, Cyanotype, and Gum Bichromate?


Daguerreotype:

daguerreotype is a process that has been in place since the 1800's and uses a metal plate to give the photo a unique mirror image. This was the first announced photographic process. Invented by Louis Daguerre it used polished sheet of silver platted copper to a mirror finish. Depending on how it is lit it will have a light or dark background which is reflected in the metal. It was most popular in 1840- 1850 and many people had portraits done this way. Yet, this process was very expensive and used many intoxicating materials such as mercury, this is why many people preferred using the cyanotype process.


Cyanotype:


Sir John Herschel discovered this procedure in 1842. But, it was Anna Atkins ( the first female photographer), a British scientist, who brought the process into the realm of photography. She did this by creating series of cyanotypes and documenting them. Anna mostly documented ferns and other plants.  This process gives the picture a blue tint appearance and is still commonly used. It was also popular because it was a lot cheaper then the daguerreotype. This process used two chemicals; ammonium iron(lll) citrate and potassium ferricyanide.  


Gum Bichromate:


This is a 19th century photographic process where the photographer uses multiple layers throughout the photo. This process is based on light sensitivity and can print any color the photographer desires. This is a blend of mechanical constraints imposed by light and lens so you can show your expression through any painting or drawing. Overall leading into a beautiful image that has multiple colors.

Project #6 Multiple Image Techniques

Panorama
This is my first panorama and I really like it. I like the blue glass and how it looks very new and sleek and then we have the other part of the building under construction. I changed the saturation and vibrance and cropped the photo giving a very fresh feel. I know my image isn't perfectly symmetrical but I think it makes it look longer and taller. I also picked this image because I think it demonstrates how something can look whole but be broken. This is scene with the different parts of the building ( the new and whole part and the broken and under construction part.) 
Panorama #2
This is my panorama image. I took numerous pictures of this bridge and stitched them together to get one full image. To edit this photo I brightened it and added a little saturation. I also played around with the vibrance and tried to make the photo look very sharp. I really like how the water has a little reflection and seems very mellow compared to the city. I also really like how we can see the buildings in the back and the colors of the buildings really pop in this picture. One of my favorite parts is the sky with the purple haze. It looks like the sun could just be going down and were seeing the last bits of daylight. That compared to the bridge shows how everything is slowing down. 
HDR Photo #2
This is my second HDR image and I really like it. For this photo I also took three pictures but because I didn't have a tripod it wasn't even and thats why we can see two rhombus shapes. Yet, I really like this. I merged this photo to photoshop and it turned out like this in the HDR setting which I thought was really cool. I like how it looks like there is  a city on the other side of the river and were just catching a glimpse of it. I cropped the photo  as well as brightened it and added a little saturation so the green was more visible. I like the sharp contrast from the rhombus to this big body of water. Overall I feel this image shows a cool aspect of HDR. 
HDR Photo #1
This is my HDR image.  This picture I took downtown during one of our field trips. I thought it would be really cool to see how the photo turned out. I took a normal photo and then changed my ISO from high and low so I had three pictures of the same thing. I then merged to HDR in photoshop. My photo didn't turn out exactly like this so I edited it to make it look like an HDR image. I intensified the saturation, brightness, and cropped the image.  
Multiple Exposures
This is my multiple exposure picture. For this assignment I wanted to take a picture of someone doing a cartwheel and then showing the different steps. I made the first image the smallest exposure only 18% and from there worked my way up to 100%. I really like this photo, I think it's very cool how step by step we can see what happened. I made the photo black and white because I thought it made the different exposures blend together well. For editing I made the photo brighter and added a contrast so the image was still visible. I also played around with the exposure to make sure all steps were seen and not blocking any of the other layers.
