The art of photography has become omnipresent in our modern lives. From newspapers and magazines to advertisements and posters, it pervades all aspects of our lives. Photographs appear in passports, ID cards, and television. Even domestic activities such as weddings and celebrations are captured by cameras. With the advent of digital cameras, these photographs can be shared on social networking websites and photo-sharing sites. Whether it is capturing the moment or reliving it, photography has become a universal language.
As the saying goes, “An image without a concept is a bad picture.” While this is definitely true, the technical aspects of a photo are often reflected in the image. Understanding how your camera controls these settings is key to enhancing your photography. The next few chapters cover shutter speed, aperture, and ISO, as well as composition. A tripod is a basic tool for many photographers. It helps create a stable base for taking high-quality photographs.
The art of photography involves the creation of positive and negative images. The camera is used to focus light on an object, which reproduces the view of the human eye. Sir John Herschel coined the term “photograph” in 1839, which comes from Greek words phos, meaning light, and graphe, meaning drawing. Photographs created before the digital age were developed, and were made by a process that required two steps: negatives were recorded on film and positives were transferred onto photographic paper.
