LBD Photography – Using exposure compensation, an image of white

Learn by Doing Photography – Practice your photography skills with weekly photography assignments. I will post a new assignment every Friday, you can post your pictures at the bottom of this post or on the DigitalCamFan Facebook. If you have any questions please refer to the guidelines, if you have no questions jump right in any time!

Photography Assignment #6 Find an image that is mostly white – snow, white rabbit on the snow, white bed comforter. Set your camera on aperture priority, expose the first picture when the camera says it’s perfectly exposed. For the next few pictures adjust your exposure compensation, as your increase your exposure you will see your gray turn to white.

Settings: ISO 100 1/500 sec at f/5.6 Exposure Compensation = +2
At the bottom of the post I have all five examples of this picture -2, -1, 0, 1, 2

Our camera sees the world as a mid-toned gray. It looks at all the light and dark in the scene and averages it out so it’s not too dark or too light but a nice average mid-tone color. This week we’re focusing on if there is too much light in the scene. For example, white snow, someone wearing a white dress next to a white car. Any scene you can think of where there is more light in the scene than dark.

When there is too much light in the scene the camera will reduce the exposure to make sure your end result is average. In general most scenes we shoot are a mix of light and dark so with an average picture your exposure is usually going to be right. It’s when there is too much dark like shooting a black cat against a black wall, or in my case too much light with all the white snow that our camera says wait a minute, too much and tries to compensate by adjusting the exposure  closer to mid-toned gray. This is when we want to use our exposure compensation…. All camera’s are differed so take a look in your manual to see exactly how to adjust your exposure compensation.

Here is  tutorial on explaining exposure compensation a bit more in depth from LyndaPodCast.

Here are my examples using -2, -1, 0, 1, 2 on the same exact picture.

Settings: ISO 100/ 1/500 sec at f/5.6 Exposure Compensation = +2

Exposure Compensation +2

Settings: ISO 100  1/1000 sec at f/5.6 Exposure Compensation = +1

Exposure Compensation +1

Settings: ISO 100 1/2000 sec at f/5.6 Exposure Compensation = 0 (Camera was happiest with this exposure)

Exposure Compensation 0

Settings: ISO 100 1/4000 sec at f/5.6 Exposure Compensation = -1

Exposure Compensation -2

Settings: ISO 100 1/8000 sec at f/5.6 Exposure Compensation = -2

Exposure Compensation -2
