Photography is the process of making photographs by exposing light over a controlled amount of time to a light-sensitive medium, such as a digital sensor or photographic film. This is done through a device known as a camera. Cameras are essentially light-proof boxes that house the light-sensitive material.

In order to properly learn the technical aspects of photography, such as what aperture and shutter speed to use, a single lens reflex (SLR) camera with a fully manual mode of operation is recommended. An entry-level SLR will have all the features needed to build a solid technical foundation.
For handheld photo- and videography, practice steady and stable holding. This enables prolonged exposure times, leading to brighter low-light photos at same light sensitivity, even more so if supported by optical image stabilisation.
For low-light handheld photography, consider using a short self-timer such as two or three seconds to avoid causing a shake during exposure by pressing the shutter button. This is especially necessary if the camera supports zero shutter lag/delay, but the firmware can not optimize low light photographs from multiple still images.
If one does approach learning photography with a film camera, it is a good idea to spend time learning how to develop the negatives and make prints, which allows the photographer employ further techniques such as push processing and an appreciation of the chemical processes involved in the craft of creating analog photographic images. Digital cameras provide instant feedback, which allows one to learn from their photograph on the spot and perhaps make another attempt.
