Using PS5/Quickmask - Giordan on Graphics | 2
Step 5- Using Filters to Distort A Quickmask
One of the most exciting ways to modify a quickmask is by using filters.
Filters will effect an active mask in the same way that they effect
a standard set of pixel values, (excluding color modifications). This
means that you can apply a texture or pattern to a mask, which in turn
can become a texture selection for you to fill with a color, or another
image, or to simply delete to the background. The general range of effects
that can be applied to a mask are as follows:
- Sharpen/blur filters- Apply special Sharpen/blur effects
to a mask, such as motion or radial blur filters. Explore the Sharpen
/Blur submenus to appreciate the full range of options.
- Texture effects- Apply textures or patterns with any
of the filters found in the Artistic /Brush Stroke /Noise/ Sketch
/or Texture submenus.
- Distortion effects- You can apply twirl or wave patterns
to a mask using the filters found in the Distort /Render /and Other
The following step by step will apply multiple filters to a Quickmask.
It shows the basic procedure for filtering a mask, as well as giving
an indication of how filters can be combined for more complex results
- Enter quickmask mode by selecting the quickmask mode button
- Select Filter>Noise>Add noise. With the Preview button selected,
you will see the noise mask effect that will result(Figure 18.8). Adjust the
various noise controls until the desired noise effect is achieved, and click
- Select Filter>Artistic>Palette Knife, and modify the settings to
create a random speckle effect. I had to lower the stroke size way
down, and increase the softness to create the effect shown in figure
18.9. Click OK to apply the effect.
- Select Filter>Distort>Wave and modify the settings to distort the
pattern(Figure 18.10). Click OK to apply the effect.
- Exit Quickmask mode to convert the mask to a selection.
