A group of photos (3-6) is required to process multi-frame noise reduction with Low Light NR. To achieve the best result, these photos should be shot at the same scene with the same shooting parameters.
1. Three to six photos are required;
2. This group of photos should be with the same resolution and shooting parameters like ISO, shutter speed, aperture value, etc;
3. This group of photos should be shot at the same scene.
Please first set the camera to the high-speed burst mode, and then shoot photos at the same scene. Please do not move the camera when you are shooting the photos (It's better to fix the camera). Make sure these photos are shot with the same parameters including resolution, ISO, exposure time, aperture value, etc. After you finish shooting the photos, please do not adjust the resolution of the photos so that multi-frame noise reduction can be processed later to achieve the desired results.
To use the Auto Grouping feature in the program, the photos being selected should have the EXIF information including resolution, creation date, exposure time, aperture, and ISO. Low Light NR will then help you automatically select the photos shot at the same scene. In some cases, for example, photos with different resolution or ISO cannot be auto grouped.
For importing, Low Light NR currently supports JPG/TIFF.
For exporting, Low Light NR currently supports JPG/TIFF.
