Applying filters

To conclude the project, you'll apply two different styles of filters to the leaves and dandelion images. Because there are so many different filters for creating special effects, the best way to learn about them is to try out different filters and filter options. ImageReady supports the same filters that areincluded with Photoshop.

To save time when trying various filters, experiment on a small, representative part of your image or on a low-resolution copy.

Improving performance with filters

Some filter effects can be memory-intensive, especially when applied to a high-resolution image. You can use these techniques to improve performance:

• Try out filters and settings on a small portion of an image.

• Apply the effect to individual channels—for example, to each RGB channel—if the image is large and you're having problems with insufficient memory. (With some filters, effects vary if applied to the individual channel rather than the composite channel, especially if the filter randomly modifies pixels.)

• Free up memory before running the filter by using the Purge command. (See "Correcting mistakes" in Photoshop 7.0 online Help.)

• Allocate more RAM to Photoshop or ImageReady (Mac OS). You can also exit any other applications to make more memory available to Photoshop or ImageReady.

• Try changing settings to improve the speed of memory-intensive filters such as Lighting Effects, Cutout, Stained Glass, Chrome, Ripple, Spatter, Sprayed Strokes, and Glass filters. (For example, with the Stained Glass filter, increase cell size. With the Cutout filter, increase Edge Simplicity, decrease Edge Fidelity, or both.)

If you plan to print to a grayscale printer, convert a copy of the image to grayscale before applying filters. However, applying a filter to a color image and then converting to grayscale may not have the same effect as applying the filter to a grayscale version of the image.

Understanding Adobe Photoshop Features You Will Use

Adobe Photoshop can be a complex tool only because you can do so much with it, however for in this video series, we're going to keep it as simple as possible. In fact, in this video you'll see an overview of the few tools and Adobe Photoshop features we will use. When you see this video, you'll see how you can do so much with so few features, but you'll learn how to use them in depth in the future videos.
