Combining Filters

Some people like things plain. I'm not one of them. I want the whipped cream, marshmallow, nuts, and cherry on my ice cream, and I'm seldom satisfied with using just one Photoshop filter. And with an arsenal of about 100 Photoshop filters (plus dozens of third-party add-ons), why shouldn't you take advantage of as many as possible? In the remaining few minutes of this hour, let's look at some interesting combinations.

Texturizer

You can add a texture to any photo, no matter what you have already done to it. The Texturizer filter (FilterTextureTexturizer) places a pattern resembling canvas, burlap, brick, or sandstone over your image, making it look as if it's on paper with that texture. The canvas texture is particularly nice if reduced in scale. Figure 16.23 shows a photo of a seascape, first treated with the Dry Brush filter and then texturized. Look for it in the color section.

Rough Pastels and Film Grain

The Rough Pastels filter adds a strong directional quality to Figure 16.24, another view of the same beach. A single filter is applied to it. However, because the Rough Pastels includes a texturizer, it's effectively two filters.

In Figure 16.25, I kicked it up a notch by adding Film Grain over the pastels, which lightened the image, and came up with what I think is an even more interesting result. Both beach pictures are in the color plate section.

The possibilities are endless. If you can imagine a style or treatment for a picture, chances are excellent that Photoshop can do it. As a final picture and final filter combination, here's how you can turn a photo into an instant mosaic. Start with any picture that has reasonably large areas of flat color. Figure 16.26 shows my original picture, the yellow lily.

At the risk of sounding like a broken record, let me leave you with a final reminder to keep experimenting. You never know what a filter or combination can do to a particular picture until you try it. The way that Photoshop calculates the filter effects means that some filters can look very different, according to the kind of picture to which they are applied. You can't always predict what will happen, but the unexpected effects are frequently wonderful.
