White Peaking Factor
It's obvious that the minimum of the White Peaking Factor equals 1 (no white segment, no spoke light
recapture).
The maximum of the White Peaking Factor (all three contributions) is about 1.8. It varies slightly with different
lamps.
The White Peaking Factor can be linear scaled between its minimum and its maximum by
means of thw White Peaking Value.
The White Peaking Value can be set by means of the command Service|Color/Brightness|White Peaking.
A dialog box is opened where the desired White Peaking Value can be entered.
A White Peaking Value of 10 is related to the max. White Peaking Factor (1.8; incl. white segment, spoke
light recapture).
A White Peaking Value of 0 is related to the min. White Peaking Factor (0, no white segment, no spoke light
recapture).
The intermediate values are set by means of the corresponding White Peak Value, which are listed in the
following table. Please note that the table lists approximate values:
