Figure 8.36

The Channel Mixer adjustment Layer

You have flexibility with the Channel Mixer. As long as the sum of the red, green, and blue channels adds up to 100%, the image will maintain the same exposure level. However, each image has different data stored on its three color channels, so you'll have to experiment in your illustration by mixing the three channels in a way that is aesthetically pleasing to your eye.

4. Try mixing Red at +40%, Green at -40% and Blue at 100%. Try another combination that sums to 100% until you are satisfied with the results that appear in the document window. Click OK to close the Channel Mixer dialog box.

5. Create a new layer and rename it Composite B&W. Press Alt+Shift+Ctrl+E to stamp all the visible layers onto this layer without flattening. This layer contains a record of all your work to date.

Let's explore artistic possibilities by applying Sketch filters to your black-and-white composite image. It's always a good idea to duplicate a layer before you alter it, so you can easily dispose of it (without altering your compositing) if you don't like the results.

6. Press Ctrl+J to duplicate the Composite B&W layer. Rename this layer Filtered. Choose Filter > Filter Gallery to open the Filter Gallery dialog box. If there are any effects in the effect layer stack, delete them by clicking the Delete Effect Layer button, repeatedly if necessary. Click the Create New Effect Layer button, expand the Sketch folder, and select Halftone. Set Size to 1, Contrast to 9, and Pattern Type to Dot.

7. Select the Graphic Pen filter. Set Stroke Length to 6, Light/Dark Balance to 52, and Stroke Direction to Right Diagonal.

8. Add additional effect layers and/or tweak the settings given in steps 6 and 7 if desired to produce a traditional artistic look for the Filtered layer. When satisfied, click OK (see Figure 8.37).

If you think the filters applied in the last step are okay, but perhaps too much of a good thing, try using Fade to reduce their cumulative effect.

9. Choose Edit > Fade Filter Gallery. Drag the Opacity slider down to 35% to partially fade out the filters you applied in steps 6 through 8.

10. Save your work as Farmhouse3.psd. Figure 8.38 shows the black-and-white illustration. If you're going to continue working through the last section, you can leave this file open for now.
