Reticulation in photoshop

Reticulation is another one of those darkroom processes that can either ruin your photo
When you’ve loaded it into Photoshop, just follow these steps.
1. Create a duplicate layer of the tower image (Layer > Duplicate Layer), to give
you a fresh canvas with which to work.

2. Choose Filter > Sketch > Reticulation to produce the Reticulation dialog box


3. Change the Density slider to a value of 24, Foreground Level to 4, and
Background Level to 13 (although you’re free to experiment with different
settings).

4. Click on OK to apply the filter. You’ll find that the texture looks very much
like real reticulation. If you’d like to see reticulation in color, you need to
merge this reticulated black-and-white version with the original color image
in the layer below.

5. To create a color reticulation, make sure the black-and-white reticulated layer
is selected in the Layers Palette, then choose Overlay from the drop-down
layer modes list at the left side of the palette This
merging mode allows the color of the underlying layer to show through, while
retaining the reticulated texture of the layer on top. (Color Dodge can also be
used to provide an interesting effect.)

6. Merge the two layers (Layer > Merge Layers or Ctrl/Command + E) to produce
the finished image.
