Making selections:

Important points about selection.

• A selection isolates one or more parts of your image. 
• By selecting specific areas, you can edit and apply effects and filters to portions of your image while leaving the unselected areas untouched.
• Photoshop provides separate sets of tools to make selections of raster and vector data.
• To select pixels, you can use the marquee tools or the lasso tools. 
• You can use commands in the Select menu to select all pixels, to deselect, or to reselect.
• To select vector data, you can use the pen or shape tools, which produce precise outlines called paths. You can convert paths to selections or convert selections to paths.
• Selections can be copied, moved, and pasted, or saved and stored in an alpha channel.
• A mask is like the inverse of a selection: it covers the unselected part of the image and protects it from any editing or manipulations you apply.
• To select a specific color or a range of colors within an entire image or within a selected area, you can use the Color Range command.
