Magic Wand Tool

A tool in Photoshop used to quickly select a part of a picture. If clicked on a the fender of a red car,
the magic wand will select the entire fender and maybe the hood and door. A setting called "tolerance"
allows the user to define the relative selectivity of the magic wand. A tight tolerance and the magic wand will only
select the highlights of the car fender. A loose tolerance and the magic wand will select the green trees behind the car.
The selections made by this tool always select areas that are connected and not divided.
