What do they do?
Noise Filters add or remove noise or pixels with randomly distributed color levels
Types of Noise Filters
- Add Noise - Applies random pixels to an image, simulating the effect of shooting pictures on high-speed film
- Despeckle - blurs image except for edges
- Dust & Scratches - reduces noise by changing dissimilar pixels
- Media -- Reduces noise in an image by blending the brightness of pixels within a selection. Eliminates or reduces the effect of motion on an image
- Reduce noise - Reduces noise while preserving edges based on user settings affecting the overall image or individual channels by clicking the advance radio button and reducing noise in each color channel. This can help an image shot in low light or with noise from scanning.
