General Concept Photography

Composition  

Composition is the placement or preparation of visual elements or ingredients in a work of art, as distinct from the subject's work. this can also be regarded as an organization of art elements in accordance with the principles of art.  

One-third rule  

One-third rule, is a general guideline followed by visual artists. the aim is to prevent the subjects and regions such as the horizon of dividing the two images, by placing them near one of the lines that will divide the image into three equal columns and rows, ideally near the intersection line.  

Odds Rule 

Odds rule states that by framing the object of interest in works of art with even number of objects in the vicinity. become more comfortable to the eye, thus creating a sense of ease and pleasure.  

Rule space  

Space rule applies to works of art photography, advertising, illustrations. imagine objects that the artist wanted to apply the illusion of motion or is supposed to make bubbles in the minds of viewers contextual.

Simplification  

Image with chaos to divert attention from the main element in the picture and make it difficult to identify the subject. by reducing the content that is not, the audience is more likely to focus on the main object. clutter can also be reduced through the use of lighting, because the bright images tend to attract the eye, as well as lines, boxes and color.  

Restrict the focus  

In photography, one approach to achieve simplicity is to use a wide aperture when shooting to limit the depth of field when used correctly in the right settings, this technique can place everything that is not subject of the picture out of focus.  

Focus  

In geometric optics, the focus is also called an image point, is the point at which rays of light coming from a point on pbjek gathered. although the focus is a conceptual point. focus has a spatial physical boundary, called the blur circle. This non-ideal focus caused by the deviation of the optical imaging.  

Auto focus  

Sophisticated camera technology now you can use auto focus for taking photographs. an auto focus or af-optic systems use a sensor, a control and motor sisstem to focus on the point of fully automatic or manually selected regions.  

Focal Ratio  

In photography focal ratio or relative aperture is marked with the symbol f of an optical system entrance pupil diameter expressed in terms of lens focal length, in simple terms, the number f is the focal length divided by the "effective" diameter apperture. This is a dimensionless number which is a quantitative measure of lens speed. is an important concept in photography.  

Aperture  

In optics, aperture is the hole or holes have travel light. more special. aperture of the optical system is the opening that determines the cone angle of light rays coming to a focus on the image area. 

Shutter speed
Shutter speed, in photography this is a term commonly used to discuss the time of exposure, effective length of time the camera shutter open. total exposure is comparable to the exposure time, or length of light reaching the film or image sensor.
