The Lasso Tool is a free selection tool.
With the Lasso Tool we can click and then drag to draw any shape selection that you want; if we release the mouse, the shape will automatically close itself by connecting the open ends with a line, or we can connect the ends ourself by dragging all the way to our starting point.
The options available for the Lasso Tool are:
We can click in a single area to select all values of pixels matching those in that area.
The magic wand is used to select a specific color in the image.For example if we had a picture of sky with clouds,and if we wanted to select the sky and not the clouds means we can use the Magic Wand tool.
Magic Wand Properties:
It controls the Magic Wand mode by setting Threshold value.If the threshold is high value, more area will be selected
we can draw your own custom shape but instead of being freeform, the shape is drawn in the form of interconnected straight lines.
