Photomatix Pro User Guide 18
Moving them to the left reduces clipping at the extremes. The White Point slider sets the value for the
maximum of the tone mapped image (pure white, or level 255). The Black Point slider sets the value for
the minimum of the tone mapped image (pure black, or level 0). The default values are 0.
• Temperature: Adjusts the color temperature of the tone mapped image relative to the temperature of
the HDR source image. Move the slider to the right for a warmer, more yellow-orange colored look. Move
it to the left for a colder, more bluish look. A value of 0 (default) preserves the original color temperature
of the HDR source image.
• Saturation: Adjusts the color saturation of the tone mapped image. The greater the saturation, the more
intense the color. The value aects each color channel equally. The default value is 0.
3.5 Fusion/Natural Settings
• Strength: Sets by how much local contrast is accentuated.
Moving the slider to the right tends to brighten the shadows
and to show more details in the highlights. Moving the slider to
the left produces a more 'natural' eect. The default value is 0.
• Blending Point: Adjusts the weighting given to the
underexposed versus overexposed images. When you move the
slider to the right, overexposed images are favored, which has
the eect of brightening the image. The reverse applies when
you move the slider to the left. The default value is 0.
• Shadows: Adjusts the brightness of the shadows. The default
value is 0.
• Local Contrast: Increases the contrast and sharpness of details
in the image. Increasing local contrast may have the side eect
of making noise more visible, and of creating thin halo eects
around strong luminosity edges. Values near the maximum
tend to give a surreal look to the image. The default value is 2.
• Color Saturation: Adjusts the saturation of the color channels.
The greater the saturation, the more intense the color. A value
of -10 produces a grayscale image. The default value is 0.
• White Clip: Species how much the highlights are clipped.
Move the slider to the right to increase contrast and remove
details in the brightest highlights. The default value is 0.
• Black Clip: Species how much the shadows are clipped. Move
the slider to the right to increase contrast but remove details in
the darkest shadows. The default value is 0.
Fusion/Natural Settings
• Midtone: Positive values brighten the image but reduce the overall contrast. Negative values darken the
image but increase overall contrast. The default value is 0.
• 360º Image: Checking this option eliminates the seam between the left and right sides of a panorama
viewed in a 360º panoramic viewer. The seam would otherwise show because Fusion Adjust takes into
account local contrast, assigning dierent tonal values to the right and left parts of the image. The default
value is unchecked.
