Camera Settings & Composition

Composition: composition is the placement or arrangement of visual elements or ingredients in a work of art.


Rule of Thirds: The rule of thirds makes use of a natural tendency of the human eye to be more strongly drawn towards certain parts of an image.

Rule of Thirds in Photography:


Triangular Composition in Photography:


Negative Space in Photography:


Camera Settings:


ISO

The letters ISO on your digital camera settings refer to the sensitivity of the sensor to light.
Low ISO value = low light sensitivity and high image quality.
High ISO value = high light sensitivity, lower image quality.
An ISO value of 100 or 200 is suited to photographing in sunny conditions
An ISO value of 400 or 800 is suited to photographing in cloudy conditions or dusk/dawn
An ISO value of 1600 or higher is suited to low light conditions, e.g.darkened rooms, night photography.

Effect of Digital ISO setting on image quality


Aperture.
The aperture adjusts the size of the opening through which light passes to the image sensor.

Note: The main f stops in your camera are 2.8,4.0, 5.6, 8,11,16,22, 32.  for each increase in f stop value the amount of light entering the camera is reduced by a half.

The aperture adjusts the size of the opening through which light passes to the image sensor.
The aperture can be opened up to let in more light or closed (stopped down) to let in less. In respect to just exposure, smaller apertures let less light strike the image sensor so the image is darker. Larger apertures let in more so it's lighter.
To attain the right exposure for a given aperture setting adjust the shutter speed.  E.G. if the image is over exposed (as indicated by the camera exposure meter) increase the camera shutter speed until the exposure meter indicates a correct reading.


Shutter speed.
Shutter speed means timing and duration of opening and closing of the shutter curtain at the back of the camera. A fast shutter speed will freezes action while slower speed creates blurring effect.
1/500  1/250  1/125  1/60  1/30  1/15  1/8  1/4  1/2      1

The main ISO in camera settings are AUTO, 100, 200. 400, 800, 1600, 3200, 6400.
The main aperture settings are
The main shutter speeds are 30", 15", 8", 4", 2", 1", 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125
