Photography Basics
Photography comes from the Greek words meaning “light writing” and first became known back in
1839 by Sir John Herschel. For many years prior to this, people had discovered ways of causing certain chemicals to
change color when exposed to light but they did not discover ways of getting the images to remain permanent until
later on.
Now photography is a big part of our culture, something that everyone recognizes. Most everyone has family photos
lying around their house, many people take these photos on a regular basis, preserving precious memories for years
to come. Even if you don’t have your own camera, you have seen photos in magazines, used on billboards and
advertisements and more.
What is Photography?
Photography is defined as “The art or process of producing images by the action of light on surfaces sensitized by
chemical processes.”
The average person never has to deal with this technical definition because they take their
photographs to a lab to be processed. They simply take pictures with their camera and then drop them off
somewhere to be developed. They get their prints back on nice glossy paper that they can then keep to see the
images at any time they wish.
There are also instant develop photographs, commonly known as the Polaroid, in which the paper itself contains the
chemicals needed and when the paper sits for a few seconds exposed to light the photo will develop. Many people
enjoy these because you could view your photo almost instantly but over the years, the quality has improved with
other films and many people migrated to other types of cameras.
The common types of film are 35mm and 110. These film rolls come in different speeds that are meant for different
lighting and situations and are loaded into your camera, used until the end of the roll and then sent for
developing.
