Here are some ways to reduce noise in Photoshop:
1. Click on “Filter,” hover over “Noise,” and click “Reduce Noise.” Set the value of “Strength” to 0% to start. After you reduce the noise as much as you can, drag the “Preserve Details” slider to the right to bring back the detail of the image.
2. Use the Adobe Camera Raw noise reduction panel.
3. Try the advanced noise reduction filter in Photoshop.
4. Use an external noise reduction plugin, such as Topaz Denoise AI, Noiseware, or Luminar.
5. Stack several images via smart objects.
