Photography is the science, discipline, and art of taking photographs by using light, either by means of an optical camera, electronically by using an x-ray sensor, or by using a fluorescent light-sensitive substance like photographic film. It is used by a lot of people to capture the beautiful scenery that is all around us. There are many different areas in photography which you can choose to specialise in. You can take photographs of animals, landscapes, people, flowers, and anything else that you want.
The main part of photography is capturing the images on the film-or digital-camera. This is done with a lens which is a tube shaped piece of glass, usually mounted on a tripod which is fixed to some kind of support. The lens can focus a rays of light to produce an image, and the photographer needs to have a proper shutter speed, aperture, and even a good sense of timing to be able to capture an image in time. Shutter speeds can vary depending on the type of lens you are using, the conditions (such as low light or high altitude), and what type of subject you are trying to photograph.
Some smartphone manufacturers have created phones that allow photographers to attach their lenses directly to their smartphones without the need for a tripod. This allows the photographer to change lenses without having to get up from the table and take the phone down from the table. This technology is currently only available in selected countries, but the popularity of smartphone cameras has made this technology available globally in the near future.
