Camera Settings and composition

Composition: describes placement of relative objects and elements in a work of art

The 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.


Painters have long recognized the visual strength and stability that a triangle can bring to a composition.



Negative space: The area which surrounds the main subject in your photo .


Camera Settings:



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


Aperture: 



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: 


ISO: measures the sensitivity of the image sensor. The lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds.
