Photography is an art form that involves capturing images on film or digital devices. The process of photography can be used to document events and places as well as communicate ideas and emotions. It can also be used to help human beings gain a better understanding of their world, as in the case of scientific and photojournalistic photography.

The first photographs were created in 1826 and since then creators have been able to capture the world around them on film or digital media. The most basic part of photography is deciding what you want to photograph; this is known as having a vision. Once you have a vision, it becomes necessary to learn the technical side of photography in order to achieve it. This includes things like light and composition, which can have a huge impact on the final image.

Early photographers experimented with color photography but it was very difficult to create because long exposures required hours or even days of time. This was because early photography didn’t allow for the image to be “fixed,” which prevented the colors from fading rapidly in bright light.

Today, most photos are taken using cameras that can capture a full spectrum of light, including infrared. Some of the most popular uses for photos include real estate photography, which focuses on the interior and exterior of a property; food and product photography, which is often used for commercial purposes; and nature and wildlife photographs, which are often exhibited as art.
