Due to advances in technology, photography has become more convenient and accessible throughout the years. When photography was first invented, it required an expert with advanced training in handling photographic equipment and darkroom chemicals. Developing pictures was time-consuming and expensive. Photography has become more accessible to hobbyists with the advent of digital photography. Now many people take photos and share them online within minutes.
Photography was invented in the 1830's. The first type of photograph was the Daguerreotype, which required an expert-level knowledge to take pictures. The long exposure times required people to sit still for up to 20 minutes. This made the Daguerreotype impractical for spontaneous pictures and portraits. It was used mainly for formal portraits of upper-class families.
In the middle of the 20th century, photography became more accessible when the Polaroid SX-70 camera was invented. Polaroid SX-70 pictures developed instantly. They did not require lengthy processing in a darkroom. By the 1970s, most families had photo albums filled with vacation pictures and captures of other special moments.
Digital photography went mainstream in 2007 with the invention of the iPhone. It was more convenient than ever to take pictures and share them with the world. Using a Wi-Fi network, a photographer could upload their pictures instantly to a social networking site. This made photography more convenient and popular.
