Frequency Separation
- Create a copy of the Background Layer
- Rename the top: High Frequency
and the bottom: Low Frequency - Turn Visibility Off - Top Layer (High Freq)
on the Bottom: use Filter > Gaussian Blur > (use a radius that is high enough to smooth but not so high it obliterates all of the features) - Top layer / High Freq
Image > Apply Image - Layer: low frequency layer
- Blending: Subtract
- Scale: 2
- Offset: 128
- Set the Top Layer blend mode: Linear Light
- All tone corrections should be done first on the bottom Low Freq layer
Select with the Lasso, set the Option Bar Feather to something high like: 12px
Gaussian Blur (not enough to create damage) - Then use the Clone Stamp on the High Freq layer
Set to "current layer"
Use varying Opacity settings to smooth out irregular textures
Notes:
The Top High Frequency Layer - is the Texture
The Bottom Low Frequency Layer - is the Tone and Color
