Filtered B&W is a controlled color to black-and-white conversion. Rather than perform an exact conversion (as is done when applying the B&W effect; see page 82), Filtered B&W is accomplished by simulating the use of a color filter with black-and-white film. The resulting image depends on the colors in the original photo and the color filter selected.
.Open the picture for editing, click the Effects tab, and click Filtered B&W. In the Filtered B&W panel, click in the Pick Color box to set the shade of the initial color filter.
When you're satisfied with the effect, click Apply. Or click Cancel if you've changed your mind.
