Learn how to reduce noise in Photoshop using the Reduce Noise filter and a Surface Blur pass, and understand what actually causes noise in the first place.

We start with the exposure triangle, ISO, aperture, and shutter speed, to explain why noise shows up in your images, then dial in the Reduce Noise filter's Preserve Details and Reduce Color Noise sliders before finishing with a Surface Blur to clean up what's left.

CHAPTERS
00:00 What creates noise: ISO, aperture, shutter speed
03:30 Identifying noise in your image
04:01 Opening the Reduce Noise filter
05:09 Preserve Details and Reduce Color Noise sliders
06:36 Reducing remaining noise with a Surface Blur
09:55 Combining both techniques for a final pass

THE STEPS
1. Duplicate your background layer
2. Go to Filter, then Noise, then Reduce Noise
3. Bring up Strength until noise reduction becomes visible
4. Lower Preserve Details to reduce more of the grain
5. Raise Reduce Color Noise to clean up red, green, and blue speckling
6. Leave Sharpen Details at zero so you don't bring noise back
7. Duplicate again and apply Filter, then Blur, then Surface Blur
8. Balance the Surface Blur's radius and threshold for a clean final image
