A photograph (also known as a photo, or more generically referred to as an image or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor. The process and practice of creating such images is called photography.
Most photographs are now created using a smartphone or camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would perceive.
A contact print is a photographic image produced from film; sometimes from a film negative, and sometimes from a film positive or paper negative. In a darkroom an exposed and developed piece of film or photographic paper is placed emulsion side down, in contact with a piece of photographic paper, light is briefly shone through the negative or paper and then the paper is developed to reveal the final print.
The defining characteristic of a contact print is that the resulting print is the same size as the original, rather than having been projected through an enlarger.
A greeting card is a piece of card stock, usually with an illustration or photo on its front cover, made of high-quality paper featuring an expression of friendship, love, celebration, or other sentiment. Greeting cards are traditionally given on special occasions such as birthdays, weddings, anniversaries, baby showers, baptisms, and graduations, or during the holidays, including New Year's Day, Valentine's Day, Easter, Halloween, Thanksgiving, and Christmas. Greeting cards can also be sent to express other feelings, such as giving thanks, sympathy, encouragement, or best wishes to get well from an illness or injury.
Greeting cards are usually packaged using an envelope and come in a variety of styles. There are both mass-produced and handmade versions available and they may be distributed by hundreds of companies large and small. While typically inexpensive, more elaborate cards with die-cuts, pop-ups, sound elements or glued-on decorations may be more expensive.
United Press International (UPI) is an American international news agency whose newswires, photo, news film, and audio services provided news material to thousands of newspapers, magazines, radio and television stations for most of the 20th century until its eventual decline beginning in the early 1980s. At its peak, it had more than 6,000 media subscribers. Since the first of several sales and staff cutbacks in 1982, and the 1999 sale of its broadcast client list to its main U.S. rival, the Associated Press, UPI has concentrated on smaller information-market niches.
