You may experience artifacts at the edges where the blended region of one projector overlaps the
pond of
mirrors
of its neighbor. In the example below, the blended image comes from
two projectors
,
1
and
2
. Both
images have black level uplift applied; as a result,
artifacts
3
and
4
have emerged at the edges where the
black level uplift region of one projector overlaps the pond of mirrors of the other.
To remove the artifacts, you need to slightly reduce the size of the black level uplift region of each projector so it
does not overlap the pond of mirrors of the other projector.
l
Depending on your array, use
Top

Bottom
,
Left
and/or
Right
to reduce the black level uplift size. In the
example below, use the
Right
slider of the
projector on the left
1
to remove the
artifact on the right

, and the
Left
slider of the
projector on the right
2
to remove the
artifact on the left
