photoshop eraser tool
Photoshop provides you with multiple eraser options to work with as per your requirement namely eraser tool, background eraser tool and magic eraser tool. Lets have a look at each of them.
Eraser tool allows you to erase the contents of the document as effectively as an eraser would do on a piece of a paper. It erases the subject or content from the document and reveals the background color which is active on the foreground/background pallette on the tools bar.
Since, eraser tool too uses the brush tip to perform the erasing task, all the regular options like brush tip preset, brush panel, opacity, flow and pressure controls are available for this tool. Lets have a look at other options.
Erasing mode allows you to choose between the brush tip, pencil tip and block as your tool to erase the subject.
- Brush - allows you to use the brush as your eraser and lets you control all the regular brush options like size, hardness, tip, brush panel, opacity, flow and airrush effect.
- Pencil - allows you to use the pencil tip as your eraser and limits your control to size, tip style, brush panel and opacity.
- Block - allows you to use eraser block with maximum hardness as your eraser when no brush related options are available.
