Black and white filtration compared 2

Colored filters are used in Black & White to control contrast within an image. A colored filter will let colors similar to it pass through the filter, creating exposure. The same filter will block colors of the complimentary color, blocking exposure. The net result is lightening of similar colors and darkening of opposite colors.

White Balance and Outdoor Photography

White Balance is a feature dealing with the color of your images. It does not effect how light or dark the photo appears.

In addition to evaluating the amount of light for exposure, digital cameras can detect the color of the light. If the camera senses too much of one color (such as amber) the camera can automatically filter the light to correct it back to daylight. This feature is called Auto White Balance.

When should you override the Auto White Balance? When the color of your photo looks incorrect.

How do you choose the setting? Look at your light source and change the white balance to that setting.
Auto White Balance (AWB) – Your camera senses the color of both your light and your subject and automatically neutralizes the color. For most people, this setting works the majority of the time. In the garden, AWB may result in colors which are not realistic due to the intense colors of the flowers, fall leaves or other vibrant subject.

Take a test shot. If your colors do not look realistic, consider changing to daylight, cloudy or shade white balance.

Daylight White Balance (sun icon) – If you have taken your test shot and find the colors to be unrealistic, consider changing your white balance to match the type of light you are shooting in. Daylight White Balance is used in sunlight for neutral color cast. Be sure to change back to AWB when you are finished shooting as Daylight will give an amber cast if used indoorsCloudy or Overcast White Balance (cloud icon) – Used on overcast or cloudy days to warm photos. Will give an amber cast if used indoors.

Shade White Balance (house with shadow icon)– Used on a clear, sunlight day when shooting in the shade. Warms photos considerably. Will give a deep amber cast if used indoors
