qj GAIN selector
This selector switches the gain of the video amplifier to match the
lighting conditions during shooting. The gains corresponding to the L,
M, and H settings are selected from the setup menu before use. The
factory settings are L = 0 dB, M = 6 dB, and H = 12 dB.
When this selector is adjusted, the new setting will be indicated on the
setting change/adjustment progress message display area of the
viewfinder screen for about 3 seconds.
For information about setting the gain values, see Section 4-7-4 “Setting the GAIN
Selector Values” (page 4-49).

1) DCC (Dynamic Contrast Control)
Also called automatic knee. Against a very bright background with the iris
opening adjusted to the subject, objects in the background will be lost in the
glare. The DCC function will suppress the high intensity and restore much of the
lost detail and is particularly effective in the following cases.
• Shooting a subject against a bright sky
• Shooting a subject indoors, against a background through a window
• Any high contrast scenes
