Chapter Lessons


Filters alter the look of an image by altering pixels

Use filters to apply special effects:– Realistic textures– Distortions– Changes in lighting– Blurring

Understanding Filters


Applying Filters

Apply filters to any layer except the Background layer

Use commands on the Filter menu

Adjust filter settings and preview the filter effect in the Filter’s dialog box


Learn About Filters and How to Apply Them Understanding the Filter Menu

The Filter menu sorts the filters into 14 categories and sub-categories

Many filters are memory-intensive:– Use of them may slow down the

computer’s performance


Sample Filters

Filter TipsDistort filters:

– Completely reshape an image– Highly resource-demanding

Pixelate filters:– Applied when the command is clicked– Do not include a preview box

Digimarc filters:– Notify users that the image is copyright-

protected

Adjusting Filter Effects

Use any of the functions listed under the Adjustments command on the Image menu

For example, modify the color balance or the brightness/contrast of a layer before applying a filter


Add Unique Effects with Stylize Filters Using Stylize Filters

Produce a painted effect by displacing pixels and heightening the contrast within an image

Apply a stylize filter to an entire layer or to a specific area of a layer

Use a marquee tool to define the area, then apply the desired filter


List of Stylize Filters

Diffuse Filter: breaks up the image– Darken Only option: replaces light

pixels with dark pixels– Lighten Only option: replaces dark

pixels with light pixels

Wind Filter: conveys directed motionExtrude Filter: converts the image into pyramids or blocks


Sample Stylize Filters

Reducing File Size

Use filters to reduce file size

For example, apply a slight Motion Blur filter to a grassy background:– Reduces the number of green colors

that Photoshop must save in the image and so reduces the file size


Applying a Filter

Flame area is selected

Alter Images with Distort and Noise Filters Understanding Distort Filters

Distort filters create a 3-D effect or reshape an object:– Difuse Glow

– Ocean Ripple

– Glass

– Wave

– Ripple

– Twirl


Sample Distort Filters

Glass

Zig Zag

Understanding Noise Filters

Noise filters give an image an appearance of texture

Apply to an image layer or to the Background layer

Rasterize a Type layer to convert it to an image layer before applying a noise filter


Optimizing Memory

Layer masks and filters can be memory-intensiveTo offset resource loss, free up memory: – Adjust settings in the Preferences dialog

box– Lower the number of states in the History

palette– Use the Purge command to free memory

used to story Undo commands, History states, and items on the clipboard


Changing Memory Settings

Windows:– Click Edit on the menu bar, point to

Preferences, then click Memory & Image Cache

Macintosh:– Select the Photoshop application, click File on

the menu bar, click Get Info, click the Show list arrow, click Memory, then change the amount of memory allocated to Photoshop in the Preferred Size text box


Alter Lighting with a Render Filter Understanding Lighting Effects

Use the Lighting Effects filter in the Render category to set an atmosphere or highlight elements in an image

Options:– Select the style and type of light

– Adjust the properties of the light

– Texturize the light


Using Lighting Style and Type

A dozen lighting styles are available:– Spotlights– Floodlights– Full lighting

Lighting types include:– Directional– Omni– Spotlight


Understanding Lighting Types

Directional lighting:– Washes the surface with a constant light

source

Omni lighting:– Casts light from the center

Spotlight lighting:– Directs light outward from a single point


Adjusting Light Settings

Adjust light settings in the Lighting Effects dialog box:


Properties to Adjust

Gloss property– Controls the amount of surface reflection

on the lighted surfaces

Material property– Controls the parts of an image that

reflect the light source color


More Properties to Adjust

Exposure property– Lightens or darkens the ellipse

Ambience property– Controls the balance between the light

source and the overall light in an image


Adding Texture to Light

Use the Texture Channel to add 3-D effects to the lighting filter

Procedure:– Select one of the three RGB color

channels, then drag the Height slider to the relief setting required
