Assists: allows the operator to choose a signal analysis waveform. Selections include Wave-
form Exposure, RGB Parade Histogram, Focus Assist and Focus Overlay.
If Waveform is selected, a color-coded waveform illustrates the exposure values using the full
width of the lower section of the camera display. As exposure reaches maximum, waveform
color changes to yellow and then red. At minimum exposure, the waveform color changes to
light blue then dark blue. These colors match those used in the False Color Meter.
If RGB Parade is selected, a corresponding histogram illustrates the exposure distribution in
the R, G and B channels using the full width of the lower section of the camera display.
If Focus Assist or Focus Overlay is selected, a full screen width red rectangular box will ap-
pear centered on the center cursor of the image. The vertical position of this sample box can
be adjusted by rotating the Joystick, and its height can be adjusted by moving the joystick left
or right. Press the joystick to fix the sample box. The average focus value of the pixels in the
sample box are shown in a full width graph restricted to the lower section of the camera dis-
play (Focus Assist) or overlaid in the lower section of the active video (Focus Overlay)
Zebras: To adjust Zebras, highlight the ZEBRA label, and then push the joystick.
Zebras: enables and adjusts the upper and lower values for two independent Zebra indicators.
One zebra may be used for highlight exposure, and the other for mid tone or shadows.
Zebra 1 default settings are for highlight indication with LOW IRE at 90 and HI IRE at 108.
Zebra 2 default settings are for 18% gray indication with LOW IRE at 44 and HI IRE at 47.
To use Zebra 2 as a shadow exposure indicator, set Zebra 2 LOW IRE to 0 and HI IRE to 5.
This corresponds to Dark and Medium Blue in the False Color Meter
Areas of the image exposed within these ranges will be indicated by crosshatched overlays.
Zebra 1 crosshatch pattern is oriented NW/SE and Zebra 2 is oriented NE/SW. Where the Ze-
bras overlap, Zebra 1 has display priority.
