User Manual

Temperature Reference
When the Method menu is set to Temperature, the Temperature reference control is used to set
the color temperature of the source image. If the Lock Black/ Mid/White checkbox is
deselected, different references can be selected for each color range.
Temperature Result
Use this control to set the target color temperature for the image. If the Lock Black/Mid/White
checkbox is deselected, different results can be selected for each color range.
Use Gamma
This checkbox selects whether the node takes the gamma of the image into account when
applying the correction, using the default gamma of the color space selected in the Space
menu at the top of the tab.
Ranges Tab
The Ranges tab can be used to customize the range of pixels in the image considered to be
shadows, midtones, and highlights by the node.
Spline Display
The ranges are selected by manipulating the spline handles. There are four spline points, each
with one Bézier handle. The two handles at the top represent the start of the shadow and
highlight ranges, whereas the two at the bottom represent the end of the range. The Bézier
handles are used to control the falloff.
The midtones range has no specific controls since its range is understood to be the space
between the shadow and the highlight ranges.
The X and Y text controls below the Spline display can be used to enter precise positions for
the selected Bézier point or handle.
