Travel Fotography



Tripod

Tripod is a word generally used to refer to a three-legged object, generally one used as a platform of some sort, and comes from the Greek tripous, meaning "three feet". A tripod provides stability along the side-to-side and up-and-down Coordinate axis of motion and provides a large amount of leverage. Tripods have the disadvantage of being heavy and bulky although they can be used with large equipment.

Tripods are used for both motion and still photography to prevent camera movement and provide stability. They are necessary when slow-speed exposures are being made, or when telephoto lenses are used, as any camera movement while the shutter is open will produce a blurred image. In the same vein, they reduce camera shake, and thus are instrumental in achieving maximum sharpness. A tripod is also helpful in achieving precise framing of the image, or when more than one image is being made of the same scene, for example when bracketing the exposure. Use of a tripod may also allow for a more thoughtful approach to photography. For all of these reasons a tripod of some sort is often necessary for professional photography. In relation to Film/Video use of the Tripod offers stability within a shot as well as certain desired heights. The head of a Film Camera Tripod allows free flowing movement with which you can easily track a subject or pan left/right as well as tilt up and down. The use of a tripod within film/video is often a creative choice of the Director.

Macro photography

Macro photography (or photomacrography or macrography,and sometimes macrophotography) is extreme close-up photography, usually of very small subjects, in which the size of the subject in the photograph is greater than life size (though macrophotography technically refers to the art of making very large photographs). By some definitions, a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. However in other uses it refers to a finished photograph of a subject at greater than life size.

"Macro" lenses specifically designed for close-up work, with a long barrel for close focusing and optimized for high reproduction ratios, are one of the most common tools for macro photography. (Unlike most other lens makers, Nikon designates its macro lenses as "Micro" because of their original use in making microform.) Most modern macro lenses can focus continuously to infinity as well and can provide excellent optical quality for normal photography.

High Dynamic Range

High-dynamic-range photographs are generally achieved by capturing multiple standard photographs, often using exposure bracketing, and then merging them into an HDR image. Digital photographs are often encoded in a camera's raw image format, because 8 bit JPEG encoding doesn't offer enough values to allow fine transitions (and introduces undesirable effects due to the lossy compression).

Any camera that allows manual over- or under-exposure of a photo can be used to create HDR images. This includes film cameras, though the images may be digitized for processing with software HDR methods.
