Light or dark patches appear on saved image

After applying Ghost Reduction to my image, strange light or dark patches have appeared. How to I remove them?

These light or dark patches on the image have appeared as the result of improper ghost reduction. If there is no movement in your image, turn Ghost Reduction off. If there is movement in the image and Ghost Reduction is necessary, there are a couple of ways to address the issue:

1. Change the strength of the Ghost Reduction.
2. Select a different image for your Ghost Reference. A normal exposure is recommended for the best results.
