To develop light sensitive paper you need a light safe and well ventilated room, developing chemicals, and a place to dry the paper. Darkrooms come in all shapes and sizes depending on where they are, who is using them, and how much developing is needed. Below are a few examples of some darkrooms.
In the next coming post I will be posting the students pinhole paper negatives and their inverted images. Also if anyone is interested I will be making a blog post on how to aquire supplies for pinhole camera photography and sunprints.
-Kippy Camera Obscuras are inexpensive to make and are a great way to look at how light travels. It also provides a glimpse of how our eyes work. A subject is illuminated outside the camera and the subject is projected through the lens and flipped over on the opposite wall. This is what happens in our eyes but our brains flip the image right side round so that we recognize the subject. To make a pinhole camera all you need is an enclosed box/container, black paint/paper, an alluminum can, black tape, and a pin to make the lens. Ensure your container is light tight by either painting with black paint or covering completley in black paper. Cut out a square inch of the center of your container to place your lens. For your lens cut out a square inch from an alluminum can and tape it over the center hole on your container. Next, use your pin to poke one hole in the center of your alluminum piece. This is your lens. Finaly use a piece of black tape as a shutter to cover your lens. To capture an image you need photographic paper. All photographic papers consist of a light-sensitive emulsion, consisting of silver halide salts suspended in a colloidal material - usually gelatin- coated onto a paper, resin coated paper or polyester support. This paper is very light sensitive and has to be protected from light before you are ready to take the image. The paper must be loaded in a light tight room where light can't get to it. After loading the paper in your container find an image you want to take. Below is a reference guide of how long to expose the paper for a good image. Once you have taken your image you must process it in darkroom chemicals to see your image. When you take a picture with a pinhole camera you are making a negative. Below on the left is what develops from the pinhole camera. You must invert it to see the positive of your negative. This can be done in the darkroom using an enlarger or digitally on the computer.
Visiting Artists turned the 4th grade trailer into a Camera Obscura. Camera Obscura loosely translates to "Dark Room". It is essentially how a camera works. Create a light tight container, add a lens, and allow the image to be projected on the opposing wall. This is how many artists use to create work as shown in the diagram below. The 4th grade scientists returned to a room that was completely darkened up except for one small hole. After the lights were turned off and our eyes adjusted we began to see the outside projected inside the classroom. (Unfortunately we did not take pictures of this sequence) Researchers inquired about how they were seeing an image of the outside world in their classroom. This questioning led to experimenting with filters over our lens and how the suns rays travel in to the classroom. They later reflected on this experiment and the inquiries it led too relating it back to the science book.
Our final result below! Look how striking they look!
Cyanotypes or sun prints are a monochromatic photographic process that results in a blue (cyan) print. Cyanotype is what they used to reproduce blueprints and diagrams a hundred years ago. Sun printing is a great way to look at the structures of plant life. We can examine the lines and shapes of plant life by looking at the negatives left behind. We are left with a clear outline and shape of the object. How to Make a Cyanotype:
