8.0 ADJUSTING THE IMAGE
R599790 - FORCE Series User Manual 57
Standard settings are:
• 9300K, is close to the white of many computer monitors
• 6500K, is the standard for color video, in both standard and high definition forms
• 5400K, is a standard for graphics and black and white video
• 3200K, is useful if the projected image is to be filmed or shot as part of a studio set illuminated with
incandescent lights
For all color temperatures the color primaries; red, green, and blue are unchanged and reflect the native colors of
the projector. SD Video and HD Video - Sets the output color to a specific standard value. Adjusts the colors; red,
green, blue, and white.
• User# - Select 1 of 4 user defined sets of color adjustments; defined in the Configuration menu.
Dynamic Iris
The Dynamic Iris adjusts the aperture to allow more or less light through. This will allow for deeper blacks in dark
scenes.
• Enabled
Enable either Manual or Per Channel operation of the Dynamic Iris. If set to Manual, set the Iris Position control to
set the iris to a fixed position, as a percentage of fully open. If set to Off, the position of the iris will be fixed at fully
open. If set to Per Channel, the iris will operate as selected by the current channel, which may be Off, Manual or
Dynamic. This control is a global setting. All other Dynamic Iris controls are applied to channels.
NOTES:
1) Dynamic iris should not be used on blends, as this could result in image distortion.
2) Dynamic mode is only permitted in Dual lamp mode. If the global setting is set to “Per Channel” while in Dual
lamp mode, then switching to Single Lamp Mode will ignore the channel settings and will grey out the “Per Channel”
option and set the iris to 100% open. If the Dynamic Iris mode is not changed, then when switching back to Dual
Lamp mode, the iris setting will return to “Per Channel”. If the Dynamic Iris mode is changed, then when switching
back to Dual Lamp mode, the iris setting will remain at the current setting. The user will have to specifically go and
set it back to “Per Channel”.
• Iris Position
Set the fixed manual iris position as a percentage of fully open.
• Mode
Set the Dynamic Iris Mode for the current channel. Off will place the iris in a fully open position. Manual mode allows
the user to adjust the level of light to statically increase the black levels. Dynamic mode allows the iris to open/close
based on the frame content and Dynamic Iris Settings control. This will produce optimal black levels.
• Dynamic Iris Settings
There are 3 predefined settings: ‘Dark Scenes’, which produces high contrast ratios, is for movies primarily
consisting of dark content, i.e. thriller or horror scenes. ‘Medium Scenes’ is for video content containing a moderate
level of dark scenes, i.e. action movie. ‘Light Scenes’ is for movies containing only a few dark scenes, i.e. animation
or a PC source. The 4 User settings allow you to fine tune the dynamic iris and save your own settings.
• Sensitivity
Adjusts how sensitive the iris control algorithm is to small bright objects entering and leaving an image, such as
stars or candles. With a lower sensitivity value these small bright objects are more likely to be ignored, producing a
more stable light level for the image, with the side effect that some detail in those bright objects will be lost. It is often
best to adjust the sensitivity and white compression together to find the optimal settings.
• Open Speed
The open speed of the iris represents the maximum iris change per frame. Increasing this value will allow the iris to
travel further in a frame. Decreasing this value will allow for a more gradual change. A slower value will reduce any
flicker in the image, but it will also mean that the iris will not react quickly to a scene that suddenly becomes much
brighter; resulting in a image that will show a significant loss of detail for several frames.
• Close Speed
The close speed of the iris represents the maximum iris change per frame. Increasing this value will allow the iris to
travel further in a frame. Decreasing this value will allow for a more gradual change. A slower value will reduce any
flicker in the image, but it will also mean that the iris will not react quickly to a scene that suddenly becomes much
darker, resulting in an image that does not have as much contrast as it could for several frames.
• White Compression
The level of white compression adjusts amount of detail in bright parts of dark scenes. It does not eliminate the
detail in affected areas (as the sensitivity control does) but merely reduces it. The amount of detail reduction epends
