Salted Paper and Photogenic Drawing V2
I. Introduction
a. Why is the image warm in color?
This has to do with the size of the crystals in the paper and the fact that different sizes gives off different tones. Because they are relatively small in size, that is the silver crystals, they give off a warm tone. Or maybe it's the other way around?
b. Why is the image different colors when fixed with salt or with hypo?
The salt and hypo remove some of the silver crystals, and so the image acts accordingly.
c. Explain the results of the colored cellophane.
The colored cellophane blocked out some UV lights and some let the light pass through. In some places, such as with the yello, the paper was white, but with the blue the paper was dark.
d. Give an overview of the process and its history
Basically you take your paper, did it in some salt, let it dry, brush on some silver nitrate let it dry, and expose it.
e. You should bring in information from primary sources and from the reading
f. Include images
II. Links to relevant web pages, articles and videos
A good place: http://www.alternativephotography.com/wp/processes/saltprints/a-dash-of-salt.
a. Contemporary artists using this method, alternative photo
III. Describe the process, recipes and materials
a. You should reference internet sources and class materials, what did you use to make the image?
b. Also, include historic recipes from the reading. How do the methods we use in class relate to those used in the 19th century? What are some of the variations used in recipes? What manuals in google books mention these process (19th century manuals are preferable).
IV. My experience
a. Discuss your experience using the process, note observations and comments, difficulties you had, things you would do differently, scan/photo your own results
I think I got pretty good results. I used different papers with the same solution to see how they would each react and they wrere fine pictures. Though I guess the correct term would be photograms. I don't think I would do anything differently.
b. What is your hypothesis?
About what? More silver, less salt will make it more reactant. The yellow, reds and green cellophane will block out most light, while the blues and purples will be the darkest.
c. Results - How did things turn out? What would you change?
Surprisingly, the color mixes (purple, orange, green) were the lightest, as was the yellow. The red and blue were the darkest parts though I believe the blue was darker. I wouldn't change anything.
V. Miscellaneous
a. Add a section of things you find interesting, this is up to you, feel free to be creative, bring in contemporary artist, etc
VI. Summary
Explain your finding briefly and try to explain your results. This should be a brief conclusion.
19th Century Photographic Processes including Anthotypes, Photogenic Drawing, Salted paper and Photogenic Drawing, Camera Obscuras and Lucidas, Albumen, Van Dyke, and Cyanotypes.

Camera Obscura
Howdy ya'll, this here is my (incomplete) entry on camera obscuras. It's kind of dull and incomplete at the moment but I've run out of time to get this complete. My apologies.
Camera Obscura
I. Introduction
a. Why does a lens restrict the size and configuration of the camera obscura box much more than a pinhole?
With a lens, you have a definite field of view, as opposed to a pinhole, which as a field of view close to infinity. With a lens, however, the field of view is dependent on the angle of the lens, how large it is, what material it's made out of, etc. So if you have a camera obscura made with a lense, you will need to have your film x amount of inches away from the lens, the x being the distance where the image is most clearest. Therefor, you cannot have a camera that is too long or too shallow, unless you adjust for the lens. With a pinhole camera, it can be as long or shallow as you want it to be, since you will almost always get an image regardless.
b. What type of lens do you have and how does it work?
The lens provided for my camera obscura were actually part of a relatively weak magnifying glass. I used the larger of the two. To use it you first need to find that distance where the image is most sharp. You can do this in a dark room that has a bright view of the outside or use your imagination. I just sat on my bed, with a box infront of me. With the lens facing the opened window I brought it closer to the box until I had an inverted image. I then moved the lens until it was a sharp as I thought it could be and measured that distance. I think it measure around five inches, though I'm not entirely certain at this time. I then took that distance and made sure the viewing screen was at least close enough to that distance. I made my lens movable to make finding that point easier.
c.Give an overview of the process and its history.
The word Camera Obscura is latin for "a darkened vault or roof, and hence it came to denote a chamber, or box, or any other place made dark for the purpose of optical experiments" or so Thomas Dick tells us in The Complete Works of Thomas Dick, which I found using Google Books. (This is the URL http://books.google.com/books?id=_UmFeuySlZgC&pg=PA788&dq=camera+obscura&hl=en&ei=OWW3TdvqDcbdgQfhnZF8&sa=X&oi=book_result&ct=result&resnum=6&ved=0CEQQ6AEwBQ#v=onepage&q=camera%20obscura&f=false. Have fun.) He tells us that the Camera Obscura is a dark room or chamber that has a small hole at one end which is open to the outside wall. Since light travels in a straight line they will pass through the hole perfectly, and display an image of the outside inside though it will be upside. This phenomenon describes perfectly what happens in our eyes, just so you know. The reason we don't see our world upside down as it appears with a camera obscura is that our brain rights the image.
And now for the history!
d. You should bring in information (quotes!) from primary sources and from the readings.
e. include images
none :(
II. LInks to relevant web pages, articles and videos
None at the moment. :(
a. Contemporary artists using this method, alternative photo, etc
There is a band called camera Obscura. Quite interesting. Haven't listened yet, but will in the near future.
III. Describe the process, recipes and materials
IV. Your experience
a. Discuss your experience using the process, note observations and comments, difficulties you had, things you would do differently, scan/photo your own results.
Making a camera obscura isn't all that hard to do. You take a box, make a hole at one end, and voila! Instant camera. If you're using a lens, however, you need to make the hole big enough for the lens and all.
I went kind of complicated on my in that I made my lens retractable. I also made a slot so that you could fit the film through the top, if you wanted to actually use film. Also, to ensure that the screen was most visible, I made viewing holes in the back. And then, since I couldn't stand the ugly color of it, I spray painted it copper.
. Results - How did things turn out? What would you change?
Things went rather well, I don't think I would change anything other than the fact that I wish I had written this blog earlier and that I had more time to actually finish it, my apologies professor.
