Having an issue with the eraser tool.

Hello All,


I am quite new to photoshop, so thank you in advance for your patience.


When I use the eraser, I get a black line outlining the path that the eraser took.

Here, I drew a square, then erased a path through the top and left side. I now have two discrete, closed sections. I intended to get a clean erasure resulting in a two-line shape in the upper left, and a four sided, open shape in the rest of the image. Basically, I want it so they are not closed shapes.


And advice? Thanks.

    Welcome to the forum.


    I think you are doing something different than you think you are.


    To check open a new document (file/new).  Draw a black square with the paint brush then erase a section as above.  Think you will just see erased section.


    Do you have eraser in brush mode (box in eraser tool bar)?


    Do you really have a white canvas with a black line?

    I'm thinking you are erasing pixels on a layer that has a Stroke layer style.  Stroke means that wherever the layer borders between visible pixels and complete transparency there will be a line drawn.

    If it's indeed what Noel suspects (stroke layer style) then you could add a layer mask, set in the Blending Options>Layer Mask Hides Effects

    and paint on the layer mask with the brush tool set to black (the foreground color in the toolbox).

    You can use the rectangular marquee tool to draw a square and then go to Edit>Stroke, but you loose the ability of easily changing  your edits.


    You could also save a layer style and use that with shape layers (or any layer), but you would still have to add a layer mask unless you recorded an action.
