Advertising photography has been used effectively since the capability to reproduce photographs at scale. The genre covers still life and fashion photography aimed at attracting viewers and communicating information. While starting in the 1850s using printed product samples, the field grew in the 1920s-1950s with black and white then color photos in magazines. Influential photographer Edward Steichen helped advance the field in the 1920s. Modern advertising photography is now mainly digital, allowing for instant review and image manipulation. Successful ads have well-lit, sharp products composed to leave space for text in an appealing style.
