Travel is the movement of people between distant geographical locations. Travel can be done by foot, bicycle, automobile, train, boat, bus, airplane, ship or other means, with or without luggage, and can be one way or round trip.^[1] Travel can also include relatively short stays between successive movements, as in the case of tourism.

A hike is a long, vigorous walk, usually on trails or footpaths in the countryside. Walking for pleasure developed in Europe during the eighteenth century.^[1] Long hikes as part of a religious pilgrimage have existed for a much longer time. "Hiking" is the preferred term in Canada and the United States; the term "walking" is used in these regions for shorter, particularly urban walks. In the United Kingdom and the Republic of Ireland, the word "walking" describes all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling, hillwalking, and fell walking (a term mostly used for hillwalking in northern England). The term bushwalking is endemic to Australia, having been adopted by the Sydney Bush Walkers Club in 1927.^[2] In New Zealand a long, vigorous walk or hike is called tramping.^[3] It is a popular activity with numerous hiking organizations worldwide, and studies suggest that all forms of walking have health benefits.^[4][5]

Photography is the art, application, and practice of creating 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.^[1] A person who makes photographs is called a photographer.
