Have you ever experienced that the colors of your photos does not seems to
correspond to the colors of the scenes in front of you? Let this app help you
to get more realistic and better looking photos!

How to Use the App?

Find a surface that is white or gray. A white paper with or without text works
perfectly. Just make sure to avoid any colors. Point the camera towards that
surface and click the Analyze button. The app will then show the measured
color temperature of the light that falls on that surface. The app will also
recommend a white balance setting for you to use on your camera in these
lighting conditions.

What is Color Temperature?

Color temperature is a characteristic of visible light that measures the hue
of light from a light source. Color temperatures are usually measured in
Kelvin (K). Low color temperatures (below 3000 K) are called warm colors (red
and yellowish white) while high color temperatures (above 5000 K) are called
cool colors (blueish white). Technically the color temperature is the
temperature of an ideal black-body radiator that radiates light of comparable
hue to that of the light source.

When is Color Temperature Important?

Color temperatures are of special interest in all kinds of color photography.
The human eye easily compensates for the color temperature of different light
sources. Most cameras today have a feature called Automatic White Balance,
AWB, which tries to do the same. In some conditions this works OK, in other
conditions the results are poor. Many photographers therefore prefer to
manually set the white balance value on the camera to match the color
temperature of the current scene. With this application you can measure the
color temperature before doing the white balance setting on you camera to get
a more accurate setting.

You can also use this app to learn about the color temperatures in your
environment. With this knowledge you can develop a better understanding of how
the color temperatures varies which helps you when you are trying to master
the light and colors in your photography.

How Accurate are the Measurements?

To measure the color temperature accurately is a complex issue. On an
Android(TM) device is it complicated further by the fact that all devices are
slightly different from each other. See the measured values as fairly good
approximations.
