Rules of thirds : Exposure and Aperture

Photography


Rules/ Guidelines

- Natural frames
- Think about cropping before taking picture

The picture above shows the bee in the middle third and the flower in the right-hand third

Natural Frame

This could be trees, buildings, structures, fences or anything which acts as a frame around the subject of your image.

Organising People

Be assertive, balance out the subjects in your image if there is more than one person.

Exposure

Shutter speed: how long the light is let light in

Aperture: how much light is let in to the camera

ISO: the sensitivity of the camera sensor




ISO: International Organisation for Standardization

ISO: Measured in hundreds.
The higher the number the more light is let in.

Shutter Speed 

Shutter speed is measured in seconds – or in most cases fractions of seconds. The bigger the denominator the faster the speed (ie 1/1000 is much faster than 1/30).

Aperture

How much light is let in to the camera

Shallow depth of field (focus on one thing) f/22

Deep depth of field (focus on everything) f/2.8





Shallow depth of field testing in class,

We experimented with different shutter speeds to create different lighting pictures.
