In this exercise I waited until the evening light was closely matching the output from the tungsten bulbs in my apartment and took some portrait pictures with the white balance adjusted to three different settings to compare the resulting images. The settings used was daylight, auto and tungsten. The idea behind this exercise is to have a better understanding of the control of white balance and create ideas of how white balance can be used to manipulate the mood of an image and also to consider what more artistic options may be available by using white balance as a tool in the composition process.
WB-Daylight
In this image the overall effect is a warm golden yellow tone. Nikon D800e, 50mm f/1.8, 1/30sec, f/1.8, ISO-640, +1 step exposure compensation.
WB-Auto
The auto white balance has produced a similar image to the daylight setting, perhaps more orange to the tone. Nikon D800e, 50mm f/1.8, 1/90sec, f/2, ISO-1250, -1 step exposure compensation.
WB-Tungsten
The tungsten setting had created a very cold blue tone to this image. Nikon D800e, 50mm f/1.8, 1/90sec, f/2, ISO-1250, -0.5 step exposure compensation.
Fluorescent
Using fluorescent type technology energy saving bulbs to light this room, I took the following photos using the settings options of white balance from Auto, Fluorescent, Fluorescent A6 and Fluorescent B6 on my Nikon camera. Nikon D800e, 24-120mm f/4 @ 120mm, 1/60sec, f/4, ISO-6400.
WB-Auto, colour temperature 2900.
WB-Fluorescent, colour temperature 3950.
WB-Fluorescent A6, colour temperature 4550.
WB-Fluorescent B6, colour temperature 3350.
