Photography

 

Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.

Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

It is often used by serious runners as a means of active recovery during interval training. For example, a runner who completes a fast 400 meter repetition at a sub-5-minute mile pace (3 minute km) may drop to an 8-minute mile jogging pace (5 minute km) for a recovery lap. Jogging can be used as a method to increase endurance or to pro

TOURISM

TOURISM is the  act and process of spending time away from home in pursuit of recreation, relaxation, and pleasure, while making use of the commercial provision of services. As such, tourism is a product of modern social arrangements, beginning in western Europe in the 17th century, although it has  antecedents  in Classical antiquity. Tourism is distinguished from exploration in that tourists follow a “beaten path,” benefit from established systems of provision, and, as befits pleasure-seekers, are generally insulated from difficulty, danger, and embarrassment. Tourism, however, overlaps with other activities, interests, and processes, including, for example,  pilgrimage . This gives rise to shared categories, such as “business tourism,” “sports tourism,” and “ medical tourism ” (international travel undertaken for the purpose of receiving medical care). The world is facing an unprecedented global health, social and economic emergency with the COVID-19 pandemic, travel and tourism is
