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
