Global effect 2
A DMX value of 20 enables fine adjusting of the red, green and blue gamma curve at overlaping edges to achieve
consistent colour (brightness) of these parts of image.
Note
. After selecting desired image segment for the gamma correction (by means of the
Global effect 1 -
Parameter 2
)
,
set
the channel
Global effect 1 - Parameter 3
to 0 in order to display blended edges of the picture
segment.
Global effect 2- Parameter 1
The parameter adjust the red gamma value at respective image adge.
Global effect 2- Parameter 2
The parameter adjust the green gamma value at respective image adge.
Global effect 2- Parameter 3
The parameter adjust the blue gamma value at respective image adge.
The second way how to adjust the red, green and blue gamma curve at overlapping edges is by means of the
channel
Gobo effect 2 Selection
on a gobo layer. The option works on the global layer and it doesn´t matter on
which layer the channel
Gobo effect 2 Selection
was activated. This option can be a suitable solution in a case
that the channel
Global effect 2
is used for another effect.
To activate the fine adjustment of blending curves.
1.
Set the channel
Gobo effect 2 selection
to 200 on any gobo layer
.
2.
Now parameters 1-3 of this effect changing the red, green and blue gamma curves.
23.2 Picture merging example
Here is an example of the image field 3x2.
1
. All fixtures that are a part of the picture merging should have a different fixture ID (
The fixture ID= the last
number of its IP address)
. The fixture´s IP address consists of four numbers separated by the dot e.g.
002.168.002.
010
.
2
. Select the same gobo/video on the six DigitalSpots 7000 DT.
3
. On all fixtures you are configuring set a DMX value=1 at the channel
Global Effect 1
.
On all fixtures you are configuring set a DMX value=6 at the channel
Global Effect 1-Parameter 1
.
4
. Set a DMX value at the channel
Global Effect 1- Parameter 3
between 151-160 to define a sharp edges of
segments for a fine alignment.
5
. On each individual fixture set a DMX value between 0-5 at
Global Effect 1 - Parameter 2
to select the segment
that the fixture will project.
6
. Use pan/tilt/zoom and keystone channels to align the projections of individual fixtures in such a way that there
is some overlap between the separate portions of the image. This overlap is necessary for the picture merging
adjustment.
7
. Set a DMX value at
Global Effect 1- Parameter 3
between 131-141 to display the segment with sharp edges for
fine adjustment by means the fine pan/tilt and keystones channels. After it set this parameter to 0 and the
channel
Global Effect 2
set to 20 to enable fine RGB gamma correction by means of the
Global Effect 2 –
Parameter 1-3.
8
. To execute the picture merging ,run the same gobo/video on all six fixtures and set the channels
Global Effect 1-
Parameter 3
to a DMX value of 0-130.
Note: In order to assure a correct playback of videos sequences , all fixtures in the picture merging system should
be synchronized to the one (master) fixture - see the chapter bellow.
