Enhance Preview Checkbox

Click the checkbox or press E to toggle.

This checkbox allows you to enhance the brightness of your image so that you can more easily see whether you've got the flattening controls just right. It does not affect the final output after you choose [ OK ].

• If the [  ] Enhance Preview checkbox is checked, the Preview Viewport will be brightened just around the flatness base level, allowing you more easily see into the dark areas.
• If the [  ] Enhance Preview checkbox is NOT checked, the Preview Viewport will show your flattened image, per your current settings, just as it will be written back to your editor.
