other value/other value (emission)
To be not bound only to standard settings, it is possible to adjust the
lightbooths luminance to a custom value. The values can be entered in
the measuring units Lux (lx) or candela per square meter (cd/m

).
4.10.4 Edit calibration
In principle there should be no need to edit the calibration performed
by SpectraView Profiler 5. There are rare occasions when the monitor
still shows a color cast after calibration (depending from the filter set
in the instrument and the phosphor or LCD filter set of the monitor). In
these cases you can edit the calibration curves manually. SpectraView
Profiler 5 offers two edit modes:
White point
In this mode you can influence the brightness in all three channels
or in 1 selected channel without affecting the shape of the calibration
curve. If you click and drag the white point, you reduce or increase white
luminance in the selected channel. Once you have reached 100% and
continue dragging, contrast, but not the intensity will be increased, but
you will lose definition in the highlights.
If you click and drag the black point, you can increase black luminance
in the selected channel, which affects the contrast ratio as well.
White point edit: On the left, the white point was raised. You can see
how many colors turn to white. On the right, lumi- nance and contrast
have been reduced
Black point edit: On the left, the black point was reduced. You can see
how many colors turn to black. On the right, lumi- nance was raised
which results in a reduced contrast
