Aperture
Aperture determines the depth of field in a photo. A high aperture photo will have a shallow depth of field and a subject in clear focus. A small aperture photo will be sharp and show the background farther out and with less blur. The two photos on the left were taken with aperture F4. The right most photos were taken with F22. |
Shutter Speed
Shutter speed determines how long the paper is exposed to the light. The rightmost photo was taken with a fast shutter speed which allowed for the capture of movement. The leftmost photo was taken with a slow shutter speed, which allowed for the capture of the movement of light because it had a longer time exposed to it.

White Balance
ISO
ISO is the sensitivity to light. Higher ISO settings are better for darker lighting. These photos, from left to right, were taken with 100, 200, 400, 800, 1600, and then 3200 ISO settings.
Pinhole Cameras
Chris Keeney
Pinhole camera photos always appear upside down because light can only travel in a straight line. This causes the light to enter the hole at a diagonal, with the highest beam of light entering at the widest angle and hitting the photo paper at the lowest point. The the photograph to the right was taken by Chris Keeney with a coffee can pinhole camera. The bottom photos were taken by Ralph Howell, Steven Dempsey, and Cameron Gile in order from left to right. |
