Photography 1 - Light - Project The intensity of light - Exercise Measuring exposure

Part 1 - Deliberately Darker or Lighter

 Metered

 +1 stop

+2 stops

The Metered exposure accurately exposes for the street scene beyond the bridge. It requires an increase of 2 stops to give an acceptable exposure for the sign and area under the bridge. However, this completely over exposes the area beyond the bridge. The single stop increase provides probably the best balance.

 Metered

 -1 stop

Reducing the exposure by 1 stop increases the depth of the colours.

 -1 stop

 Metered

 +1 stop

A slight over exposure is required if the name of the pub needs to be read. It may be possible to reduce this over exposure without losing the readability of the signage.

 Metered

 +1 stop

Exposure of an additional stop slightly burns out the shutters but brings out the details in the signage that is otherwise indistinguishable.

 -1 stop

 Metered

Exposure of minus 1 stop returns the detail to what otherwise would be a washed out image.

 Metered

 +1

 -1

The image at minus one stop exposes the principle to its best advantage.
