First up….The Selection Tools
The selection tools are used to create selections of shapes, colors, and objects on the canvas, and manually positioning them in the working image area.
In Photoshop, selections are used to work in a specified area, while not altering any of the area around it.
Marquee Tool
When you want to make a rectangular, elliptical, horizontal or vertical line selection you use the marquee tools. To create a selection with a marquee tool, hold down your mouse button over the active image area, and create your shape.
Lasso Tool
The Lasso Selection Tool is used for those times you need an irregular shape. To use the tool, click and drag a your selection with your mouse.
When you use the Polygonal Lasso Tool, you can click to make various points that will define a custom selection, when you return to your starting point you are finished.
The Magnetic Lasso Tool uses the the first two tools mentioned. You click once, and begin to drag a manual selection around the object you wish to select. The magnetic lasso tool attempts to dynamically create target points itself while you follow the edge of your object (you can define points by clicking if needed). The end result is generally a much cleaner and smoother selection than the polygonal lasso tool is able to do.
Magic Wand Tool
The Magic Wand Tool selects areas based on color. To use this tool, click the color you want to select in the active image area.
Combining Selections
Sometimes, you need to combine multiple selections in order to select the entire area you want to work with. In these situations, it’s possible to combine multiple selections using an easy keyboard shortcut.
When you need to highlight an unusual shape sometimes you will want to combine multiple selections. There is an easy shortcut that allows you to add to an already existing marquee. By holding down shift it will add your new selection to the existing selection.
Subtracting Selections
In order to subtract from an existing selection hold Alt when using the marquee tool
Move Tool
The Move Tool is used for moving selected areas of an image, layers, shapes, and other objects.
To move a selected part of an image (marqueed), select the move tool, and then click and drag your selection. This will cut out the selection from its location, and allow you to move it .
Crop Tool
The Crop Tool is used to re-size a canvas. To use the crop tool, drag out a square that encompasses the area which you want to become the new canvas size. You can set it to delete the cropped out area or just make it invisible.
