ToneZones
™
Tool
Selecting the ToneZones™ tool from the top set of buttons will colorize the preview image to
allow for rapid assessment of the image tones. When the ToneZones™ tool is selected, the grayscale
beneath the histogram display will be replaced by a color zone display and a popup menu. is easy-
to-use exposure tool assigns false colors to user-defined ranges of data to quickly identify areas within
the preview that fall into those exposure levels. ToneZones™ can be used to rapidly locate areas that
might be under or over exposed or to adjust certain regions of an image into a specified data range.
e default color zones are set to show highlight regions without much detail as red, highlight
regions with detail as yellow, midtone values as green, dark values with detail as cyan and dark tones
without detail as blue. ese are only default values and each zone may be adjusted, deleted, have the
color changed and additional zones can be added.
A zone may be turned off by clicking and releasing the mouse in the colored area of that zone.
When a zone’s color is white, the portions of the preview image with those tone values will be shown
normally. Clicking once again in the zone’s color bar region will turn that zone on and those sections
of the preview image with the values for that zone will be replaced with the zone’s specified color.
To change a zone’s range, click and hold the mouse button on the vertical bar at either end of
the zone and move the bar to the left or right. e RGB values for all the zones will appear at the top
of the ToneZones™ display and the bar being adjusted will be highlighted in red text. Moving the bar
to the left will decrease the RGB value and to the right will increase the value.
A new zone may be added by pressing and holding the Option key
(Alt on Windows) while
clicking the mouse at the location in the ToneZones™ bar for the new zone end. New zones are
assumed to begin at the end of the previous lower value zone. e default color for the new zone is
assumed to be gray until it is changed. You may need to create an “empty” or normal zone to isolate a
new zone.
e color for a zone may be selected by pressing and holding the Command key
(Control key on
Windows) and clicking on the color bar for a zone. e system color picker will appear. e color will
be applied when the color picker is closed.
