Describing The Camera
Before describing the camera, let us understand in brief what is camera? The camera is the image-forming device, and photographic film. Photography techniques have always been a subject of interest to many scientists, while captivating the artists from its inception. The main focus of this page is to shed light on the description of camera, explaining its different controls.
Focus -The adjustment for placing the sharpest focus desired on the subject.
Aperture - Measured as f-number, Aperture is the adjustment of the lens opening, controlling the amount of light passing through the lens. Aperture also affects the depth of field and diffraction. This is an important element while describing the photography camera.
Shutter speed- Expressed either as fractions of seconds or as an angle, the adjustment of the shutter speed is for controlling the length of time during which the imaging medium is bared to light for each exposure.
White balance – Photographers use white balance to register natural coloration of the image for aesthetic ends. The color temperature connected with a given set of lighting conditions makes sure that white light is registered as such on the imaging chip, so as to offer natural colors.
Metering – This is the measurement of exposure so as to control the highlights and shadows according to the liking of the photographers. Most modern cameras are able to meter and set the exposure automatically. ISO speed – While describing the camera, one should not forget ISO speed, which is used to communicate to the camera the film speed of the selected film on film cameras. The ISO speeds are used on modern digital cameras to indicate the system's gain from light to numerical output, besides controlling the automatic exposure system.
Autofocus point – This is employed by some cameras, to select a point in the imaging frame upon which the auto-focus system will endeavor to focus. Today, many advanced reflex cameras are able to feature multiple auto-focus points in the viewfinder.
While explaining the camera, it is also important to mention many other elements and controls that may have a distinct effect on the quality and visual effect of a given photograph. These are the focal length and type of lens, which can be “long" lens, macro, wide angle, fisheye, or zoom. The filters placed between the subject and the light recording material, are also important elements in the camera description. They are placed either in front of or behind the lens. The inherent sensitivity of the medium to light intensity and color/wavelengths also play an important role. Finally, the nature of the light recording material, its resolution as measured in pixels or grains of silver halide are important to any photographer. Using the photography techniques play a very important role in this medium.
