Adobe Photoshop/Eraser Tool
Almost everyone knows what an eraser does. It removes a section of a picture. It can be very easy to use if used basically, or very complicated if used to its full potential.
The Tool
[edit | edit source]Start by clicking the eraser tool 
. Then scroll over to the Image and click + drag to remove portions of the image. It can be that simple.
Complicated Options
[edit | edit source]You already have seen how to use the basic eraser. But this tool can do much more then just remove squares.
Mode
[edit | edit source]The mode option sets the eraser to act as a block, a brush, or a pencil. A block acts as a simple square eraser, a brush acts a brush with varying opacity, and a pencil acts as a 1px*1px eraser.
Brush
[edit | edit source]The brush, unlike the other options, requires a little more explanation. Next to "Mode" you will see the "Brush" option. This allows you to set the shape. This is explained further in the Brush lesson.
Opacity
[edit | edit source]This sets how much it erases off the picture. at 100%, it removes everything it touches, and at 0% it removes nothing.
