Still life photography involves photographing inanimate objects without movement. It has been popular since the early 19th century when photographers adopted the genre from painters. Early on, long exposure times made photographing landscapes and people difficult, so still life was a practical option. Advertising discovered the power of still life photography in the early 1900s. A successful still life relies on refined lighting and compositional skills from the photographer to make the image rather than simply take it. The definition of still life has broadened over time to include a wider range of static subject matter.
