Digital Noise Pustules

What Is Digital Noise Pustules
Clusters of hot pixels or noise artifacts (“pustules”) that appear as bright specks.

How to Spot Digital Noise Pustules

• Tiny white, red, or green dots especially in dark areas.
• Popping when zooming into the image.

Causes of Digital Noise Pustules

• Long-exposure sensor heat.
• High ISO in low-light conditions.

Fixes for Digital Noise Pustules

• Use a pixel-repair tool or median denoise filter (e.g., DaVinci’s temporal noise reduction).
• Capture dark-frame calibration to subtract sensor noise.
• In post, apply a subtle patch-based cleanup brush.
