| I like using high frequency and low frequency in the 'Lum channel'.
Use favorite method to extract Lum.
For the high, use High Pass and flip it over. Leave it for now.
For the low, use Gauss and flip it over.
Gross painting over the Gauss copy for major highs and lows.
I like to flip between Normal and Lum blending modes for this.
Eventually clip the High Pass copy, set to Linear Light, and lower Opacity as needed.
Various cleaning along the way, like Layer Masks, clipping groups, and things.
If you can get the Lum to look good, the rest should fall into place without too much fuss. |
