Parts of the Camera

• Shutter Speed: Opens for a small interval of time to allow light from the object to enter the camera.

• Aperture: Also called f-aperture located near the lens. It controls the amount of light entering the camera.

• ISO: Controlling the amount of light that your camera will be sensitive to.

• Lens: Produces a real image of the object that one wishes to capture on the film or CCD.

• Film/Digital Chip: A thin flexible strip of plastic or other material coated with light-sensitive emulsion for exposure in a camera.

F/5.6, Shutter: 13”, ISO: 100

•This light painting was done with a rainbow pixel stick. The shutter was open for thirteen seconds, and a person ran across the hill with the pixel stick. With the shutter being open for a long period of time, the light from the pixel stick was recorded, giving the photograph the effect of a rainbow behind the people.

F/10, Shutter: 6”, ISO: 100

•This long exposure light painting was done with smoke and a flashlight. We lit a flare and let the smoke come over the hill. Shortly after, we lit the smoke with a flashlight. The shutter was six seconds, so the only light that got through was the light highlighting the smoke and the person. The ISO was 100, so the film speed did not allow much light to get through.

F/5.6, Shutter: 15”, ISO: 200

•This long exposure and light painting was a little harder to attempt because if the subject moved, the subject would be blurry. It was very dark outside, and the only light was from the flashlight, so the ISO needed to be bumped up to 200. The highlights on the ground are from the light of the moon reflecting off of the water. The shutter speed was at fifteen seconds and the aperture was 5.6, allowing light to come through and over expose the darkness of the photograph.

F/5.6, Shutter: 13”, ISO: 200

•This light painting was done with steel wool. We lit the steel wool on fire and spun it around very quickly. We took turns spinning the steel wool vertically and horizontally. This gives the light the cone shape. With a thirteen second exposure, and a 200 ISO and 5.6 aperture, the camera was able to capture the light and the light streaks that were flying off of the steel wool.

•This long exposure light painting was done with the pixel stick. One of us had a rainbow pixel stick and ran across the rocks, while spinning it. The long shutter speed allowed us to capture both the alternating colors, but also the reflection in the water of the light. Since the pixel stick was a lot darker than the steel wool, the background appears to be black, while in the steel wool photograph the background appears to be blue. This is because not as much light was recorded on this photograph as the steel wool one.
