ZoneMapper: Adjusting contrast
5 of 8
One of several adjustments you can make to your photo
using the ZoneMapper tool is contrast.
Contrast adjustments using the ZoneMapper tool
are performed by stretching or compressing the luminance range.
Before adjusting contrast, however,
you first need to identify the luminance range you want to adjust.
You can use the
ZoneFinder
for this.
To increase the contrast of your photo:
-
Click the ZoneMapper tool button in the
tool bar.
(A new ZoneMapper tool will appear at the top of the
tool stack.)
-
Move the mouse along the zones in the ZoneMapper
to locate the zone above which
you do not want to adjust contrast.
(As you move the mouse,
you can see the zones highlight in the ZoneFinder.)
-
Click to add a zone lock
(a thin, blue line with a little 'X' at its right).
-
Similarly, move the mouse along the zones
to locate the zone below which
you do not want to adjust contrast.
-
Click to add a second zone lock.
-
Drag the upper zone lock upwards
and the lower zone lock downwards.
As you do so,
the contrast of the midtones of your photo will increase.
-
Optionally:
-
To delete a zone lock,
click the little 'X' at its right.
Note:
To decrease the contrast of you photo,
drag the zone locks towards each other
rather than away from each other.
