The next job is to flatten the layers by choosing Flatten Image from the Layers palette’s flyout menu (found in the upper-right corner of the palette itself). To sharpen the photo, I choose Filter > Sharpen > Unsharp Mask. When the dialog box appears, I specify 120% for Amount, 1.0 for Radius, and 3 for Threshold (see Figure 12). These settings give a nice punchy amount of sharpening. When your subject has a lot of well-defined edges, as a car does, the image can take a lot of sharpening like this without damaging the photo. If this were a portrait, on the other hand, that probably would be too much sharpening, giving the photo little halos around the edges and looking noticeably oversharpened.
