This up/down scroll selection switch allows a choice between three preset colour temperatures:

•3200K (3.2K) - for studio lighting conditions

•5600K (5.6K) - for outdoors, clouded conditions

•FL- memory position for fluorescent light

•AW1 - memory position 1

•AW2 - memory position 2

and an automatic continuous white position:

when using the +++ position.

7Clean Scan button

When shooting computer monitors with higher frame frequencies than the camera use the Clean Scan function to avoid horizontal noise bars in the picture.

Press the Clean Scan button for two seconds to directly access the variable exposure (clean scan) function. Use the rotary control to change the value and so remove the bar. When you are finished shooting the monitor press the Clean Scan button for two seconds to switch off the Clean Scan function.

When the Clean Scan function is on, the non-standard indicator in the viewfinder lights. Refer to Section 5 for more information on shooting screens.

8White Balance switch

This momentary switch is used to start the automatic white balance process. The camera, when pointed at a white area in the centre of the picture, measures and stores a colour temperature setting in the FL, AW1 or AW2 memory position.

The white balance switch only operates if the colour temperature is set to the FL, AW1 or AW2 position. Refer to Section 5 for more information on how to use the automatic white balance.

Note

Black balance is not necessary with this camera because of the continuous automatic black control circuits.

Nom.	- nominal setting
Var.	- enables the exposure to be varied
Crt	- for shooting sync-locked monitors [FT]
EVR	- enhanced vertical resolution position [IT]
