Colour temperature selection

Auto-White Balance

For true colour reproduction the ambient lighting conditions must be compensated for by selecting a value for the colour temperature. The standard file setting is 3200K (normally used for tungsten light). Two other reference colour temperatures are available; 5600K (for outdoors, clouded conditions) and 7500K (for outdoors, clear blue skies).

Three similar memory positions (FL, AW1 and AW2) are available to store the results of the auto-white measurement process. The FL position is recommended for shooting with fluorescent light.

A continuous automatic white balance position (AWC) is also available. This function continuously measures the white balance and adjusts accordingly. It can be used when a constant colour balance is required under changing lighting temperatures (sunsets, indoors/ outdoors use). When AWC is selected none of the colour temperature indicators in the 1.5-inch viewfinder light.

The colour temperature is selected via the up/down scroll switch (White Bal.) at the left-front side of the camera. The viewfinder displays the current value. A new value is chosen by scrolling up or down through theavailablevalues.Thecolourtemperaturesareshown in the following order:

White balance : 3200K

White balance : 5600K

White balance : 7500K

White balance : FL

White balance : AW1

White balance : AW2

White balance : AWC

The viewfinder displays the selected value and the actual measured colour temperature. The range of the auto-white balance is from 2.5K to 20K.

In the auto-white positions an electronic colour filter can be adjusted in the system Video menu. This varies the colour balance to obtain warmer or colder colour effects. When an automatic white balance process is performed, the electronic colour filter is reset to its default value.

If the reference colour temperatures do not match your lighting conditions carry out the auto-white procedure as follows:

a.Use the colour temperature switch to select one of the memory positions FL, AW1 or AW2 in which to store the measured colour temperature value.

b.Press once on the white balance switch at the front of the camera to start the automatic white balance procedure. The following appears in the viewfinder:
