I'd like to see a few additions to the Grad Filter. First I'd like to be able to change the shape of the line. Take the classic valley situation. I'd like to match the grad to the edge of the mountains. A single point in the line could be dragged down to create the need shape.
Modify Graduated and Radial Filter masks with a brush:
After adding or selecting a Graduated or Radial Filter instance, click the new ‘Brush’ mode (next to existing ‘New’ and ‘Edit’ mode buttons) to reveal brush controls that allow you to modify the selected mask.
Use the ‘Brush +’ and ‘Brush -’ icon buttons in the brush controls pane to add to or erase from the selected mask.
Press the ‘Clear’ button to remove all brush modifications from the currently selected mask.
When a Graduated or Radial Filter instance is selected, Shift-K can be used to enter and leave brush modification mode.
Mask visualization is now available for the Graduated and Radial Filters. Use the Mask checkbox at the bottom of the Local Corrections pane or press ‘Y’ to toggle the mask overlay.
