The Liquify View Options control what you see in the preview window.
For example, you can choose to view or hide a mask, or even change
its color. If the image you're working on is in a transparent layer you
can even choose to view the image with or without the other image
layers. How you view the image is up to you; however, having choices
gives you greater control over the final results.

You may have noticed the Load Mesh and Save Mesh buttons, located
at the top of the Liquify dialog box. A mesh is a predefined Liquify oper-
ation. When you activate the mesh option, a mesh or grid is placed over
the image, and then as you use the Liquify tools, the mesh distorts and
bends. After applying a lot of work to a particular image, it's quite pos-
sible you might want to use that exact mesh on another image. That's
where the Load Mesh and Save Mesh options come into play. With the
click of a button you can create a mesh and use it over and over again.

You can display the distortion created
by the Liquify tools.
Check this option
to display a mesh (grid) over the image
preview. When you select the Show
Mesh check box, a mesh is applied to
an image, which distorts as you apply
the Liquify tools. When you clear the
Show Image check box (dimming the
image), you get a visual grid that repre-
sents the distortion values applied to
the image.

Applying a mesh to an image is a lot easier than redoing a particular
Liquify operation and to be honest, it would be virtually impossible to
reproduce a Liquify adjustment from scratch. That's why Adobe gives
you the option of creating, saving, and loading your very own personal-
ized meshes.

You can modify a loaded mesh.
Open a
mesh, and then use the Liquify options
to further distort the mesh pattern. That
way you can create a generic mesh
pattern and modify the pattern to fit
any design need.

The Lens Blur filter creates a varying depth of field so that certain
objects stay in focus and other areas become blurred. What stays in
focus and what is blurred is determined by a user-defined selection or
alpha channel. When the filter is activated, a depth map is created to
determine the three-dimensional position of the pixels in an image. If
you use an alpha channel, the black areas in the alpha channel are at
the front of the photo, and the white areas are in the distance.
Experiment with selections and alpha channel masks to see how pre-
cisely you can control the visual effect of blurring in an image.

The Photo Filter command reproduces the same effect of placing a col-
ored filter in front of the camera lens when you take a picture.
Photographers place colored filters in front of a camera lens to adjust
the color balance of the image and control the color temperature of the
light transmitted through the lens. In addition to simulating a color filter,

the Photo Filter command also lets you select a color preset and apply
a specific hue adjustment to an image. If you want to apply a custom
color adjustment, the Photo Filter command lets you specify a user-
defined color using the Adobe Color Picker.
