| ||||||||||||||||||||||||||||||||||||
Focus, Frost, Iris, and Zoom are functions in the DDFs for DMXControl 3, which are assigned to the group Light beam and primarily affect the width of the light beam. The GUI provides a corresponding Control Panel for this purpose.
Focus
The focus function is particularly used for the motorized "sharp focusing" of gobos for moving heads and scanners and can be expanded to a resolution of 16 bits by inserting finedmxchannel="1".
| Case | Code example |
|---|---|
| Standard | <focus dmxchannel="0">
<range mindmx="255" maxdmx="0" minval="0" maxval="100" />
</focus>

Frost
The frost filter can be used to soften a light beam. Some devices have a so-called linear frost filter, where the light beam can be increasingly softened. Other devices, on the other hand, only insert a disk with a frost filter into the light beam.
| Case | Code example |
|---|---|
| Linear frost filter | <frost dmxchannel="0">
<range mindmx="0" maxdmx="255" minval="0" maxval="100" />
</frost>
Frost on DMX channel 1:
|
| Simple frost filter | <frost dmxchannel="0">
<step type="open" mindmx="0" maxdmx="127" />
<range type="linear" mindmx="128" maxdmx="255" minval="100" maxval="100" />
</frost>
Frost on DMX channel 1:

| Attribute | type | mindmx | maxdmx | minval | maxval |
|---|---|---|---|---|---|
| Description | DMX value for no frost filter | DMX value for frost filter inserted | No frost | Frost inserted | |
| Permissible attribute value | open |

Iris
With the iris, the size or projection range of the light beam can be varied. The iris works in lighting technology just like the iris in a camera. Unlike the zoom, the beam angle does not change with the opening and closing of the iris. With the iris almost closed, only a small portion of the light beam is allowed through the aperture.
The iris function can be expanded to a resolution of 16 bits by inserting finedmxchannel="1".
| Case | Code example |
|---|---|
| Standard | <iris dmxchannel="0">
<range type="linear" mindmx="0" maxdmx="128" minval="0" maxval="100" />
</iris>
Iris on DMX channel 1:
|
| Attribute | type | mindmx | maxdmx | minval | maxval |
|---|---|---|---|---|---|
| Description | DMX value for smallest aperture | DMX value for largest aperture | Smallest aperture (closed) | Largest aperture (open) | |
| Permissible attribute value | linear

Zoom
The zoom function changes the beam angle / opening angle of the device's light beam. It should not be confused with the iris. The zoom function can be expanded to a resolution of 16 bits by inserting finedmxchannel="1".
| Case | Code example |
|---|---|
| Linear zoom | <zoom dmxchannel="0" >
<range mindmx="255" maxdmx="0" minval="14" maxval="30" />
</zoom>
Zoom on DMX channel 1:
|
| Zoom in multiple fixed steps | <zoom dmxchannel="0">
<step val="15" mindmx="0" maxdmx="85" />
<step val="20" mindmx="86" maxdmx="171" />
<step val="25" mindmx="172" maxdmx="255" />
</zoom>
Zoom with three fixed opening angles on DMX channel 1:
|
| Attribute | type | mindmx | maxdmx | minval | maxval |
|---|---|---|---|---|---|
| Description | DMX value for smallest opening angle | DMX value for largest opening angle | Smallest opening angle | Largest opening angle | |
| Permissible attribute value | linear
