Camera Settings and Composition

Composition
Rule of thirds: How the screen is split into nine squares to show where the points of interest are in an image. 
Definition: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 third images:





Composition
Triangular composition:Three points of interest that form a triangle.






Negative Space:An image that only has one isolated focal point/point of interest.





Camera Settings
ISO:
Definition: The International Organization for Standardization 
Low ISO = low light sensitivity and high image quality
High ISO = high light sensitivity and lower image quality

ISO of 100/200 best suited for photography in sunny or high light conditions

ISO of 400/800 best suited for cloudy/dusk conditions

ISO of 1600 is suited to low light conditions such as night photography or darkened rooms. 

ISO values increase as follows 50, 100, 200, 400, 800, 1600.  

For each step change the light sensitivity doubles

Apature:

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

Changes the field of depth. 

High F number means lots of detail/ but lots of noise
(noise = grainy bits)

Narrow Field of depth: Low F value (Below 4/2.8)

Shutter Speed:

Measured in fractions of a second.

These are the main Shutter Speeds:

1/500  1/250  1/125  1/60  1/30  1/15  1/8  1/4  1/2 1”  15" 30"

Note: reducing the shutter speed from 1/60th of a second to 1/30th 

increases the amount of  light exposure by a factor of 2.

The Main Setting Examples:

ISO: 100/200/400/800/1600/3200

Low ISO = low light sensitivity and high image quality
High ISO = high light sensitivity and lower image quality

F:(Apature) The size of the hole that controls the amount of light hitting the sensor
