Brownie was the name of a long-running and extremely popular series of simple and inexpensive cameras made by Kodak. The Brownie popularized low-cost photography and introduced the concept of the snapshot. The first Brownie, introduced in February, 1900, in the USA. It was a very basic cardboard box camera with a simple meniscus lens that took 2¼-inch square pictures on 117 roll film. With its simple controls and initial price of $1, it was intended to be a camera that anyone could afford and use.  One of the most popular Brownie models was the Brownie 127, millions of which were sold between 1952 and 1967.
The Brownie 127 was a simple Bakelite camera for 127 film which featured a simple meniscus lens and a curved film plane to reduce the impact of deficiencies in the lens

A snap-shot is popularly defined as a photograph that is "shot" spontaneously and quickly, most often without artistic or journalistic intent or a casual photograph made typically by an amateur with a small hand-held camera and without regard to technique and an impression or view of something brief or transitory. Snapshots are commonly considered to be technically "imperfect" or amateurish--out of focus or poorly framed or composed. The term derives from the snap shot of hunting. Common snapshot subjects include the events of everyday life, such as birthday parties and other celebrations; sunsets; children playing; group photos; pets; and the like.
The snapshot concept was introduced to the public on a large scale by Eastman Kodak, which produced the Brownie Box Camera around 1900. Kodak encouraged families to use the Brownie to capture moments in time and to shoot photos without being concerned with producing perfect images. Kodak advertising urged consumers to "celebrate the moments of your life" and find a "Kodak moment."
