® About the Highlight AJert
When the [D: HighJight alert] menu is set to [EnabJe], overexposed
highlight areas will blink. To obtain more image detail in the overexposed areas,
set the exposure compensation to a negative amount and shoot again.
® About the AF Point DispJay
When the [D: AF point dispo] menu is set to [EnabJe], the AF point
which achieved focus will be displayed in red in the shooting
information display and histogram display, if automatic AF point
selection was used, multiple AF points might be displayed in red.
® About the Histogram
The brightness histogram display shows the exposure level
distribution, overall brightness, and gradation. And the RGB histogram
display is for checking the color saturation and gradation. The display
can be switched with the [[]: Histogram] menu.
[Brightness] DispJay SampJe Histograms
This histogram is a graph showing the distribution of the image's
brightness Jevet.The horizontal axis indicates the brightness level
(darker on the teff and brighter on the right), while the vertical axis
indicates how many pixels exist for each brightness tevel. The Dark image
more pixels there are toward the Jeff,the darker the image. And the
more pixels there are toward the right, the brighter the image. If
there are too many pixeis on the Jeft the shadow detail witl be lost.
And if there are too many pixels on the right, the highlight detail will
be Jost.The gradation in-between will be reproduced. By checking
the image and its brightness histogram, you can see the exposure
level inclination and the overaJl tone reproduction condition.
[RGB] OispJay
This histogram is a graph showing the distribution of the image's brightness level of each
primary color (RGB or red, blue, and green). The horizontal axis indicates the color's
brightness Jevel(darker on the teft and brighter on the right), while the verticaJaxis indicates
how many pixets exist for each color brightness Jevet.The more pixets there are toward the
left, the darker and tess prominent the color. And the more pixels there are toward the right,
the brighter and denser the color, if there are too many pixels on the Jeft, the respective
color information witJ be lacking. And if there are too many pixets on the right, the color wiII
be too saturated with no detait. By checking the image's RGB histogram, you can see the
color's saturation and gradation condition and white balance inclination.
