LASSO TOOL
-Used for drawing free-form segments
of a selection border.
Three types of Lasso tools in
Photoshop
1.Lasso
2.Polygonal Lasso
3.Magnetic Lasso
-- Used for making free-form
selections.
Lasso Tool
1.Lasso Tool
(default)
- It is the basic selection
tool and is used to draw
freehand selection.
2. Polygonal Lasso Tool
This tool is used to select box
shapes or flat edges, etc. This lasso
tool creates a straight line in
between each mouse click. So, just
simply click on any edge of the area
that you want to select and release
your mouse pointer, this will create
a starting point or anchor point.
3. Magnetic Lasso Tool
-It is also known as an edge
detection tool. This tool is more
automated as compared to the
default lasso and polygonal lasso
tool. It automatically detects the
edge of the area or object that you
want to select as you move around it,
then snaps the selection outline to
the edge and holds it like a magnet.
QUICK SELECTION TOOL
--IS ONE OF MANY SELECTION TOOLS IN PHOTOSHOP. WHEN YOU CHOOSE AN AREA, PHOTOSHOP DETECTS
AND SELECTS THE EDGES, SO YOU DON’T HAVE TO TRACE THEM MANUALLY.
MAGIC WAND TOOL
--you can select the Magic Wand simply by
clicking on its icon in the Tools palette.
1. Tolerance
The Tolerance option tells Photoshop how different in tone and
color a pixel can be from the area we clicked on for it to be
included in the selection.
2. Contagious
Any pixels that are within the acceptable Tolerance range but are
separated from the area you clicked on by pixels that fall outside the
Tolerance range will not be included in the selection.
3. Anti-aliased
---can smooth out the edges by applying a
slight blur to them
4. Sample All Layers
---selects colors using data from all the
visible layers
