Early Photography: Camera Obscura • Camera Obscura=dark room • Some artists used these dark rooms to project images and help them reproduce images with the correct proportions Canaletto, 1700s
How does it work? • Light travels into a darkened room through a small hole, the image is projected onto the wall or a screen. • The image is upside down and backwards, but color and perspective are preserved. • The smaller the hole, the sharper the image, but it is also dimmer. • The image can be captured when photographic paper is used as the screen.

The pinhole camera is basically a small camera obscura, in which we place photographic paper to capture the image. Parsnip, Steve Irving, 120 min exposure

Tips for working with pinhole cameras Boulevard du Temple, Daguerre, 1838 Exposures outside in sunlight take between 30 sec and 2 min. The darker it is, the longer the exposure. Indoors can take several hours If your subject is moving they will be blurry or invisible.
Assignment • We are going to a continuation of the portrait project. • 1 portrait or self portrait • 1 free print • Keep in mind the elements and principles, we still want interesting compositions! • Feel free to experiment. If you move around you will be less visible on the film.

Making a pinhole camera • Must use a light-tight container • Small pinhole makes sharper images: punch hole in metal • Paint inside of container black to prevent light from bouncing around inside. • Consider making a pinhole camera out of something you find: an oatmeal container, a shoebox, a cookie tin, anything you can think of!
Making an image (negative) • Put photo paper inside your camera opposite the hole, tape in place if necessary • Make sure hole is covered. Put on lid. • Go outside, set camera down on something • Uncover the hole (expose for 30 sec-2 min) • Cover hole • Open in darkroom and process print as usual
Making a Print • Print will be a negative image, so you will make a contact print (under glass like a contact sheet) with the negative face down onto the emulsion side of a new piece of photo paper. • Stop down one aperture size (darker) • Print a test strip with 2 second intervals • Develop as usual
