Checking the INFO Window
7.1.1
Checking the Histogram of the Image
In the LIVE menu, tap [INFO] to display the [INFO:
HISTOGRAM] window in the bottom right of the display. If the
[INFO: HISTOGRAM] window does not appear, use the  or 
button (or swipe the screen) to switch the screen.
In the [INFO: HISTOGRAM] window, the distribution of
brightness of the displayed image (as calculated by the DS-L4)
is displayed as a histogram.
The histogram indicates distribution of brightness for each RGB
color, allowing for fine adjustment of the exposure level.
 The horizontal axis indicates brightness (dark (left) to bright
(right)).
 The vertical axis indicates RGB color intensity.
 To the right of the histogram, average RGB values are shown.

Reading and compensating for exposure
When the distribution reaches the right end of the histogram, bright regions of the image are saturated
(white-out). When the distribution reaches the left end of the histogram, dark regions of the image are crushed
(black-out).
Ideally, no white-out and black-out should occur in the entire image. However, in some cases, adjustment is
necessary.
If bright areas of the image are important, adjust the distribution to the left. If dark areas are important, adjust the
distribution to the right.
By adjusting the distribution appropriately for the image, insufficient gradation during image processing can be
avoided.
