This assignment involves your use of light source of some type to create or enhance your photos. In addition to a light source, this will likely involve a tripod. Your light source may be visible in the photo, for example to "paint" stripes, patterns, letters, or shapes. Or, your light source might not be visible, but instead used to selectively illuminate, brighted, or enhance areas of your photos.
Just put your 5 jpgs on a flash drive and show us what you have.
