to get consistent exposure.
♦IRIS
With this option, the IRIS priority is higher than SHUTTER and AGC; SHUTTER and AGC circuit will function automatically in cooperating with IRIS to get consistent exposure. If the IRIS is modified manually, the action of exposure compensation depends on the AGC circuit.
♦AGC
With this option, the AGC priority is higher than SHUTTER and IRIS; SHUTTER and IRIS circuit will function automatically in cooperating with AGC to get consistent exposure. If AGC is adjusted manuall, the exposure compensation depends on the changing of IRIS.
B-3-6 WBC MODE
A digital camera needs to find reference colour temperature, which is a way of measuring the quality of a light source, for calculating all the other colours. The unit for measuring this ratio is in degree Kelvin (K). You can select one of the White Balance Control modes according to the condition. The following table shows the colour temperature of some light sources.
Light Sources | Color Temperature in K |
Cloudy Sky | 6,000 to 8,000 |
Noon Sun and Clear Sky | 6,500 |
Household Lighting | 2,500 to 3,000 |
2,820 | |
Candle Flame | 1,200 to 1,500 |
¾18x MODEL ♦ AUTO
In this mode, white balance works within its colour temperature range. This mode computes the white balance value output using colour information from the entire screen. It outputs the proper value using the colour temperature radiating from a black subject based on a range of values from 3000K to 7500K.
