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.
