We recommend using the Polygonal tool, but you can use the
Normal or Magnetic tool if you prefer. Selection works dierently,
depending on the tool.
• Polygonal lasso
– Click to set the selection line’s starting point.
– Move the mouse and click to create a straight segment, attached to the previous point.
Repeat to create additional segments.
– To close the selection, double-click, or single-click on the starting point.
• Normal lasso
– Click and drag the mouse to draw a freehand selection.
– Release the mouse button to close the selection.
• Magnetic lasso
– Click and drag the mouse as with the Normal lasso. If an edge is within the Width setting, the selection
path snaps to the edge.
Fusion/Intensive Settings
3.6 Fusion/Intensive Settings
• Strength: Adjusts the strength of local contrast enhancements.
The default value is 0.
• Color Saturation: Adjusts the saturation of the color channels.
The greater the saturation, the more intense the color. A value
of zero produces a grayscale image. The default value is 0.
• Radius: Controls the area used to calculate the weighting of
the source images. A higher radius reduces halos, but increases
processing times. The default value is 70.
3.7 Replace Selection with Source
An HDR-processed image might look exactly the way you want, except for one area. For example, the sky
might have more contrast or be darker than desired. The “Replace selection with source” feature lets you
replace that area with the same area from any one of the source images, to bring the tonemapped or fused
image closer to what you want.
Selection Mode checkbox
3.7.1 Selecting the Area to be Replaced
To enable this feature, click the Selection Mode checkbox.
The Polygonal Lasso is the default tool.
