Changing the region of interest
Use the Region of Interest button to create a rectangular preview of the composition window. Reducing the region of interest requires less memory when previewing, thereby improving interaction speed and increasing RAM preview duration. Changing the region of interest does not affect file output.
To change the region of interest: - In the Composition window, do any of the following:
- To draw a region of interest, click the Region of Interest button (
), and then drag the marquee tool across the area of the composition window where you want images to appear. - To toggle between viewing the region of interest and the full composition area, click the Region of Interest button again.
- To start over with the marquee tool, hold down Alt (Windows) or Option (Mac OS) and click the Region of Interest button.
