This fortnight's photography challenge is....Nailing White Balance!
How to Set White Balance White balance is a term for how the colour temperature of the light in a scene is reflected in a photograph.
Light sources vary from cool (blue coloured light) to very warm (bright orange coloured light).
The automatic white balance (AWB) setting on an SLR camera evaluates the colour temperature of the light source that reaches the camera sensor and balances the RGB (red, green and blue) channels inside the camera to get the best result. AWB works fine for many types of light, especially outdoors.
However with some light sources one of the three RGB colours is dominant and the AWB setting canít balance it with the other two colours. This produces a colour cast in the final photograph.
For example, shade and overcast light have a slight blue cast, fluorescent light has a green cast, and Tungsten light and candlelight can have a yellow or orange cast. These types of light are most often found indoors. Flash also has the effect of making a photo appear too white and cold.
Setting your white balance is essential for capturing the colours around us correctly, and showing the world in true to life shades.
Did you know that the measurement for white balance can be described by a Kelvin Number? This is a four digit number, such as 5000 that determines how cool or how warm the photo appears. Try adjusting the Kelvin Number in the settings on your camera, or using the white balance slider in your editing software.
Cool - Neutral - Warm tones
The whites in this image appear to have a blue tone, which could indicate that the white balance is on a 'too cool' of a setting
Things that should appear white in this photo have an orangey tinge, which means the white balance could be incorrect.
There are no restrictions on the subject you choose for this theme, but we'll be looking for entries that show a good understanding of how to accurately capture colour, especially under tricky light conditions such as in the shade or with a flash.
