    Photoshop CS6 Magic Wand

    Mickyです Level 1

      Hi,

      When I select the area with magic wand tool and refilled, the edge of the selection is way rougher than before.

       

      This is before refilled.

      This is after refilled.

      How can I fix this?

          Could you show your entire screen with the layers panel open? Also capture your image size dialog box. (Image>Image Size...)

          I want to find out why your image is that pixelated. I assume it is a low resolution issue, but I hate assuming.

           

          This image is a good example to show what alising is. The edge your having an issue with is called alising. The black line which looks a bit blurred is called anti-alising. some commands have a check box for antialising and this image shows what that does.

          Anyway, back to your issue, I will wait until I see more.

            Yes. Like Bruce says.

             

            Magic wand is prone to all sorts issues if used in this way.  Refine edge will each smoothly into the AA, but I wouldn't dream of filling the spaces created with the MW.  Much better to use a new layer underneath, and fill that, using a selection to constrain the outline if required.

              This is whole screen shot.

              and this is the image size.

              I'm quite interested in the story about alising.

              Could you tell me what and how I improve this?

                OK, your pixel dimentions is high enough. For the two circles, I recommend that you use shapes instead of pixels when creating them. This will produce a better quality circle. It will also make it much easier to change its color.

                 

                When you create a selection it tends to be a hard edge. In the selection menu you will find a feather command. You can also use refine edge which will be a more visual approach. The feather will blend the edges.
