Registration
:
Registration
allows you to correct for mis-registrations of images
caused by filter-induced optical shifts. Use the directional keys to shift the selected
image in the x- and/or y- direction, with respect to the rest of the input images. One
click moves that channel one pixel in the direction indicated. Blank areas are filled
with black. The key labeled “0,0” will re-center the selected image.
The registration shift for the selected channel or the overall image is displayed in the
static text box below the directional keys.
Contrast
: Use the
BCG sliders
along with the
Best Fit
and
Reset
buttons to adjust the
contrast of the selected image or the composite.
BCG sliders
: The
Brightness
,
Contrast
, and
Gamma
sliders are the similar to the
Contrast Enhancement
feature in ToupView. You can also adjust each channel
individually or collectively by using the
Selected
or
All
radio buttons (to the left of the
BCG
sliders in the
Adjust
group box).
Best Fit
: Click this button to perform a
Best-Fit
contrast stretch on the selected input,
automatically setting the Brightness and
Contrast
settings accordingly (
Gamma
will
be reset to 50.). This method is identical to the
Best Fit
contrast adjustment under
the standard
Contrast Enhancement
feature of ToupView.
Best Fit
is useful for first
pass adjustments.
Reset
: Pressing the
Reset
button automatically resets the
BCG
settings. If the
Adjust
radio button is set on
All
, the
BCG
settings for the overall color image will be reset.
Frame
: Use the frame slider to adjust the frame of the selected image that is used for
the preview, or the active frame of the composite. (Please see the discussion of
Color
Composite
and
Image Sequences
that follows this section.)
Background
: Select one of the available images to be the background color in this
combo box. The rest of the image planes are subtracted from the background image
— effectively punching “holes” into it and allowing the foreground colors to show
without mixing with the background. This is most effective where the background
covers large areas and the other images have smaller objects within the background
objects.
