Tilt-Shift Blur alters perspective.and hazed out everything except the
selected center candle. Unlike the Field
Blur, which works best with multiple Pins
or multiple layers, the Iris Blur reacts to
everything not Pinned.TILT-SHIFT BLUR
Photographers use tilt-shift lenses to
photograph panoramic views, to modify the
scale of an area so it appears miniature, to
correct vertical lines that converge, and to
blur specific areas of an image.
In Photoshop, the effect is much the
same. A tilt-shift lens alters perspective. It
looks like it adds a rectangular window (or
strip) of sharpened focus to a blurred photo.
But, in fact, it maintains the sharp focus inside
the window and blurs out the rest in a
graduated fade.
In our example, we decided to focus on
the cabin and make the trees, mountains, and
sky on top gradually fade from sharp to hazy;
then phase out the water and reflections on
the bottom to simulate an eerie, ghostly
feeling. We divided the image into five
sections, maintained the sharp center, and
fuzzed out the rest. We chose 144 pixels for
the Blur and 55 for the Distortion.PATH BLUR
The Path Blur does the obvious: It creates a
blurred area along a selected path that
simulates motion. When you select Filter >
Blur Gallery > Path Blur, a line with an arrow
and a large pin dot appear on the right, a
small pin dot appears in the center, and
another large pin dot appears on the left.
If you drag the pin dots in any direction,
the line that connects them bends and arcs
up, down, left, right, or in and out of spirals,
