HISTOGRAM MODE
–
EXPOSURE
The histogram provides a graph that indicates the total number of pixels at each
brightness level, with brightnesses going from black on the left to white on the
right. It is a valuable tool for evaluating captures. A well-exposed shot usually has
a full range of levels, while under- and overexposed shots tend to show levels con-
centrated at the left or right part of the scale, respectively. The histogram is only
an indicator that should be interpreted – there are several situations in which a
‘bad’ histogram will match an exposure that could be perfect for the intended ef-
fect (and vice-versa). Look at the histogram examples and the explanations below:
EVEN EXPOSURE
A histogram display that is spread across the full range indicates a likely good ex-
posure. There may still be a few pixels at the extremes, indicating a few spectral
highlights and saturated shadows, but this is often normal in a good exposure.
UNDEREXPOSURE
A histogram display that is concentrated on the left with few pixels elsewhere indi-
cates a likely underexposure. Many details will be lost in the shadows.
OVEREXPOSURE
A histogram display that is concentrated on the right with few pixels elsewhere
indicates a likely overexposure. Many details will be lost in the highlights.
 BROWSING
In Browse mode use the front scroll
wheel (or left or right arrows on
the navigator button) to browse cap-
tures in a folder. Zoom out to Folder
View if you want to select another
folder to browse.

HISTOGRAM TYPES
There are three types of histogram representation available: Histogram and Full details , Combined histogram and Histogram
mode.
In Histogram and Full details mode,
you can read a list of camera set-
tings, plus see the histogram and, in
the background, a darkened preview
of the image. The setting details are
stored with the capture file, so you
can also refer to them in Phocus and
other applications.
In Combined Histogram mode, the
RBG channels are represented to
show individual distribution against
a luminosity histogram.
In Histogram mode, the individual
RBG channels are represented to
show a comparitive display.
