If you own a Samsung device with a Samsung Expert RAW on board you will be glad to hear that there was a new feature added to your app.
The feature is called ND filter which stands for neutral density.
Once the ND filter is enabled, you’ll see an ND icon in the top-right corner of the viewfinder.
When You press that button you can adjust the strength of the ND filter in multiples of two.
It starts from 2 and goes up to 1,000, which is a good option for all users interested in photography.
