The EYESbehind
the LENS
The eye behind the lens of any camera is more vital than any photographing tool and marvelous images can result with the knowledge of the essential principles of applied art in the modern artform we now know as photography.

ORGANIZATION
ISO sensitivity expresses the speed of photographic negative materials (formerly expressed as ASA).
Since digital cameras do not use film but use image sensors instead, the ISO equivalent is usually given.
- represents film speed, or the equivalent sensitivity of a digital camera’s sensor.In traditional (film) photography ISO (or ASA) was the indication of how sensitive a film was to light. It was measured in numbers (you’ve probably seen them on films – 100, 200, 400, 800 etc). The lower the number the lower the sensitivity of the film and the finer the grain in the shots you’re taking.

UNDERSTANDING ISO
Experiment with different ISO settings and how they create impact in your images.

EXPOSURE TRIANGLE APERTURE - the size of the opening in the lens when a picture is taken, or
the lens opening, or iris, that admits light to the film or sensor. F-stops are the size of the lens aperture usually measured.
SHUTTER SPEED - the amount of time that the shutter is open. In a conventional film camera, the shutter is a mechanism consisting of blades, a curtain, plate or some other movable cover that controls the time during which light reaches the film.

Understanding theLight Illumination
FRONT LIGHTING - With the source of light (sun) coming in front of the subject, the subject is evenly lit. This sort of lighting is good for accentuating color.

Front Lighting: Good foraccentuating COLOR
FRONT LIGHTING - the subject is evenly lit. Good for PORTRAIT photography.

Understanding theLight Illumination
BACKLIGHTING – a lighting effect produced when the main light source is located behind the subject. Backlighting can be used to create silhouette effect.

Understanding theLight Illumination
SIDELIGHTING – or the light source can be to the side of the subject, typically creates both strong shadows and strong highlights.

MIXED DIRECTIONAL LIGHTING – subjects can be lit from the back and side, or frontal, even bounce lighting.

MIXED DIRECTIONAL LIGHTING – subjects can be lit from the back and side, or frontal, even bounce lighting.

Understanding the Existing Light
EXISTING LIGHT– also known as the AVAILABLE LIGHT or the illumination that is already present in the scene. The beauty and challenge of natural light is that it is constantly changing, directional light that bounces and reflects.

Understanding the Fill Lighting
Without Flash
FILL LIGHTING – in photography, lighting used to illuminates shadows. Reflectors or additional incandescent lighting or electronic flash can be used to brighten shadows. One common technique outdoors is to use the camera’s flash as a fill.
With Flash

Understanding the Low-Key Lighting
LOW-KEY – Low-key lighting is a style of lighting for photography, It is a necessary element in creating a chiaroscuro effect. Traditional photographic lighting, three-point lighting uses a key light, a fill light, and a back light for illumination. Low-key lighting often uses only one key light, optionally controlled with a fill light or a simple reflector.Low key light accentuates the contours of an object by throwing areas into shade while a fill light or reflector may illuminate the shadow areas to control contrast.
Jasmine Pacatang
Understanding the High-Key Lighting
HIGH-KEY – High-key lighting is a style of lighting for photography that aims to reduce the lighting ratio present in the scene. This was originally done partly for technological reasons, since early film and television did not deal well with high contrast ratios, but now is used to suggest an upbeat mood. High-key lighting is usually quite homogeneous and free from dark shadows. The terminology comes from the key light (main light).

How to BLUR a Background
IN photography, to soften an image or part of an image by throwing it OUT OF FOCUS, or by allowing it to become soft due to subject or camera motion.

How to BLUR a Background
BOKEH – word to describe the aesthetic quality of out-of-focus parts of an image. Bokeh is a Japanese word for “blur”.

How to BLUR a Background
DEPTH-OF-FIELD – a distance range in a photograph in which all included portions of an image are at least acceptably sharp. With DSLR, you can see the available depth-of-field at the taking aperture by pressing the depth-of-field preview button.
