Removing remnant border around selected objects

[Grey24601]

Hi All,

Everytime I select an object using Object Selection or any other method and create a new file, I get a remnant border around it. I have looked at the tutorial for removing them by creating a mask and using the burn tool but it doesn't seem to work. Any ideas???

Hello and welcome!

I get a white halo around it. .................. Any ideas???

Select and mask...........just like you have showing in your sample image. Shift your edge and decon colors on output. If you still have some white remnant left, use the Brush Tool on the layer mask to remove.

Still some white!

In Select and Mask, you can try shifting the Radius under Edge Detection to bring in the selection and eliminate the white fringe.

I've also selected the mask and then used the smudge tool around the edge to bring the layer mask in towards the subject. Bit tedious on a somewhat complex image.

Another way is to select the mask, then go to Filter>Other>Minimum and try several pixel choices. Keep the setting for ssquaremess to preserve the tips of the image.
Here's my try with this:

Always many ways to get to a result. Here's another approach:

• Create a layer mask as best you can, but it will still have the problem of the white halo.
• Activate the layer mask itself and apply a Gaussian blur of one or two pixels. I used two pixels.
• Here's a side-by-side comparison of the upper-right corner of the original mask vs. the blurred mask.

• With the layer mask active, open a Levels adjustment using Ctrl+L (or Cmd+L).
• Move the black slider pretty far to the right until the mask looks good. You can also experiment with moving the white slider slightly to the left. (See red arrows, below.)
• The Levels adjustment takes the blurry gray-tones of your mask and sharpens them by either darkening or lightening.
• Finally, use the brush tool to manually clean up the few large white halos that are too big for this technique.

Thank you for your help. I tried contracting the selection but it still created a halo.

HI Thank you for your help. I tried it and it made no difference.

Hi Thanks for your help. I have tried contracting the selection but that made no difference. I will try the the smudge tool but there are a lot of complicated edges.

I can't select decontamination of colours. ?

I can't select decontamination of colours. ?

A couple things
- you need to have the layer selected that has the mask you want to adjust
- a secondary factor that may not matter yet when you initially select the object, you don’t need to delete the background, just turn the selection into a mask. You effectively have both the mask and the layer transparency working at the same time. Sometimes that has some undesired side effects

Just some quick thoughts
