Compositions

Why does the rule of thirds work?

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.

This photo is an example of the use of negative space. 

This photo uses the rule of thirds. 

This photo uses a triangular composition. 

Camera Settings 

ISO: 

The letters ISO on 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.

Aperture:

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

This photo has a narrow depth of field. (blurred background)

This photo has a wide depth of field. (all the photo is very clear)

A large f-number such as f/32, (which means a smaller aperture) will bring all foreground and background objects in focus, while a small f-number such as f/1.4 will isolate the foreground from the background by making the foreground objects sharp and the background blurry.

Shutter Speed

Measured in fractions of a second. 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.
