In addition, having photographs of items or structures in dispute can assist in discussions over the dispute. Both cameras reviewed for this column have the option to display pictures directly from the camera onto a television screen. Imagine being able to take a photograph on the way to a negotiating session, bring it with you and use it during the session to make a point. This could be a very effective use of digital photography. Taking Pictures With a Digital Camera Traditional photography uses film and chemicals that react in a certain manner when exposed to light.
Digital images replace the film and chemicals with a light sensitive photo pad inside the camera.
The light hits the pad and is converted into pixels, or dots. These dots of light are then stored in the camera as digital information. The more pixels, the better the photo quality and, generally, the larger the resulting computer file. Different cameras have different levels of resolution, and this is one feature to consider. Remember, higher resolution not only means better images, but also larger files.
