PHOTOGRAPY INFORMATION: 6) THREE THUMB RULE :  The rule of thirds involves mentally dividing up your image using 2 horizontal lines and 2 vertical lines, as shown below. You then position the important elements in your scene along those lines, or at the points where they meet. A rule of thirds grid. PHOTOGRAPY 6: THREE THUMB RULE

PHOTOGRAPHY INFORMATION: 5) SHUTTER SPEED:   In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. PHOTOGRAPHY 5 : SHUTTER SPEED

PHOTOGRAPY INFORMATION: 4) APERTUE :  In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles. PHOTOGRAPHY 4: APERTUE

PHOTOGRAPHY INFORMATION 3) BALANCE : Balance in photography is observed when an image has subject areas that look balanced throughout the composition. It is achieved by shifting the frame and juxtaposing subjects within it so objects, tones, and colors are of equal visual weight. An image is balanced when subject areas command a viewer’s attention equally. PHOTOGRAPY 3 : BALANCE

PHOTOGRAPHY INFORMATION : 2) EXPOSURE:  In photography, exposure is the amount of light per unit area reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value and scene luminance in a specified region. PHOTOGRAPY 2: EXPOSURE

PHOTOGRAPHY INFORMATION 1) DEPTH OF FIELD:  For many cameras, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus in an image. The depth of field can be calculated based on focal length, distance to subject, the acceptable circle of confusion size, and aperture. PHOTOGRAPHY 1 : DEPTH OF FIELD
