In-Depth Information
You can also create a multiple-point path or a shape. Blur shapes
describe the local motion blurs, similar to camera shake (see
“
Camera Shake Reduction
” on page
132
). The Speed slider in the
Blur Tools panel determines the speed for all the path blurs. The
Centered Blur option ensures that the blur shape for any pixel is
centered on that pixel, resulting in more stable-feeling motion
blurs; to make the motion appear more fluid, deselect this option.
You can add a
strobe effect
to spin and path blurs. Select the
Mo-
tion Blur Effects
tab to bring its panel forward. The Strobe
Strength slider determines how much blur shows between flash
exposures (0% gives no strobe effect; 100% gives full strobe ef-
fect with little blur between exposures). Strobe Flashes determ-
ines the number of exposures.
In the Blur Effects panel, you specify the bokeh parameters to
control the appearance of blurred areas. Light Bokeh brightens
the blurred areas; Bokeh Color adds more vivid colors to
lightened areas that aren't blown out to white; Light Range de-
termines the range of tones that the settings affect.
Creating a panorama
Sometimes a vista is just too large for a single shot. Photoshop makes it easy to
combine multiple images into a panorama so that your viewers can get the full ef-
fect.
