EXPOSURE
In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance.
APERTURE
Control the area over which light can pass through camera lens.It is specified in term o an f-stop value which can at times be coutererintoves because the area of the opening increase as the f-stop decrease.
SHUTTER SPEED
Shutter speed not only can be used to control movement but it can be use to control how much light is recorded on your photo. Longer shutter speeds (or long exposures) record more light. Faster shutter speeds record less light.
ISO
- The measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to measure the sensitivity of digital imaging system.
- The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera.
COMPOSITION
Composition is the placement or arrangement of visual elements or ingredients in a work of art, as distinct from the subject of a work. It can also be thought of as the organization of the elements of art according to the principles of art.
RULE OF THIRD
A "rule of thumb" or guideline which applies to the process of composing visual images such as designs, films, paintings, and photographs.One can easily visualize this rule by taking a frame and dividing the horizontal piece into three equal sections and dividing the vertical in three equal sections. This creates 9 equal sections.
DEPTH OF FIELD
Refers to the range of distance that appears acceptably sharp.It varies depending on camera type,aperture and focusing distance.
WHITE BALANCE
In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors).
