Is moire ruining your shots? You can work with the Selective Moire Reduction tool, and easily add to or subtract moire from your selection.
1. After selecting your image, go to the Adjust Panel and open the Grain and Moire Reduction menu.
2. Choose 'Selective' and then choose one of the selection tools:
- Ellipse Marquee
- Rectangle Marquee
- Polygonal Lasso or the Lasso.


3. Now you can make you selection.


To add to your selection
Press and hold down the SHIFT key, while adding to the existing selection. If you add a selection to an existing selection area, these two selections will merge to become one selected area. If you add a selection from somewhere else in the image (not touching the existing selection), it will simply add another (a second) selection.

To subtract from your selection
If you have an area selected, and you want to subtract from it, hold down the ALT key and select the area you want subtracted.
You can only subtract from an existing selection.
