In-Depth Information
The big advantage of this tool over the Magnetic Lasso is that it's much easier to keep it
from getting into a snarl. Your only Tool Options settings for this tool are Feather and Anti-
aliasing (which are explained in the box on
Feathering and Anti-Aliasing
)
, as well as Refine
Edge (
Refining Selection Edges
).
Figure 5-15. If you have limited dexterity, the Polygonal Lasso tool and a lot of clicks eventually
get you a nice, accurate selection. You just need to zoom way, way in to use this tool to select an
object that doesn't have totally straight sides. Here, the Polygonal Lasso easily made it around the
curve of this stone by clicking to make extremely short segments.
Extracting Objects
Ever feel the urge to pluck an object out of a photo so you can use it on its own or some-
where else? For example, say you want to take an amazing shot you got of the moon and
stick it in another photo. How do you do that?
