5.6 Colour temperature
For true color reproduction you must compensate for the ambient lighting conditions by
selecting a color temperature value.
5.6.1 Presets
Four presets (3.2K, 4.7K, 5.6K and 7.5K) for reference color temperatures are available:
– 3200K (3.2K) - for tungsten light (indoor)
– 4700K (4.7K) - for mixed lighting (tungsten and daylight)
– 5600K (5.6K) - for HMI (daylight) lighting or outdoors, clear sky with full sun
– 7500K (7.5K) - for outdoors, shaded conditions
5.6.2 Memory positions
Three memory positions (FL50 / FL60, AW1 and AW2) are available to store the results of the
auto-white measurement process. The memory positions are filled with measured values
using the automatic white balance switch at the front of the camcorder. The FL50 / FL60
position is recommended for shooting with fluorescent light. The three memory positions are:
• FL50 / FL60 - combined memory position for fluorescent light sources
– FL50 is for 50Hz fluorescent light sources (the color matrix is automatically set to
CoolFL and exposure to 50Hz.)
– FL60 is for 60Hz fluorescent light sources (the color matrix is automatically set to
CoolFL and exposure to 60Hz.)
• AW1 - memory position 1
• AW2 - memory position 2

Note
The measured values for FL50 and FL60 are stored in a single memory position. When a new
value is stored the old value is deleted.
5.6.3 Continuous white balance
A continuous automatic white balance position (AWC) is also available. This function
continuously measures the ambient light and adjusts the white balance accordingly. It can be
used when a constant color balance is required under variable lighting conditions (sunrise/
sunset, moving between indoors and outdoors). The automatic continuous white adjustment
can range between 2000K and 20,000K.
