Week 4: Light Painting
Eric Staller: Light Painting Photography, 1976
Eric Staller could be called the father of light graffiti or light drawing in its present day form. From 1976 to 1980 Staller roamed the dark streets of New York City creating light painting photographs:
A pixel is actually a unit of the digital image.
Resolution depends upon the size of the pixel. The smaller the size of the pixel, the higher the resolution will be and the clearer the object in the image will be. Images having smaller pixel sizes might consist of more pixels. The number of pixels correlates to the amount of information within the image.
Resolution (dpi) : describes how many pixels in a photo, written in a number that tells how many “dots” per square inch of the image; example - 72 dpi (which is very low resolution) or 300 dpi (which is a high resolution)
For use on the web use 72 dots per inch (looks “OK” on a screen)
But Best for printing – is 300 dpi, it will have more detail, see below
Sometimes Pictures come out of cameras HUUUUUUGE but at a low resolution of 72, huge photos are big files and are hard to store, work on or save to flash drives, email, use on the web.
To work in Photoshop and print, you should change all photos to 300 dpi in Photoshop, and change the size of the image to about 9” by 12” or else the images will 5 feet wide.

SD Cards: Secure Digital (SD) is a memory card format developed for use in portable devices which has become the industry standard.
(The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC).
Card Reader: an electronic device that reads and transfers data from various portable memory storage devices. Care must be taken inserting card!
We will be using tripods: In photography, a tripod is used to stabilize and elevate a camera, a flash unit, or other photographic equipment. All photographic tripods have three legs and a mounting head to couple with a camera.
