A halo / fringe or not?

[k_5099]

I am new to photoshop. I have an image which I removed the background. After removing the background I added a black layer to check the background was removed ok and there were no stray white edges and it appeared correct in photoshop so I saved as a PNG. When looking at the folder where the PNG is stored it looks like there is a white halo surrounding it - but I cannot see it in photoshop. Any ideas why it looks like it has white edges in the desktop folder? Thanks!

Hey @k_5099!

Try Layer > Matting > Defringe to remove edge pixels. Let me know if that helps.

Hi @CMass  thanks for responding 🙂 I tried that and saving but when I look at the folder where I saved the image as a PNG it still looks like there is a white line outside the letter - but I find that hard to believe since when I removed the background I removed a fex pixels and then I also used the contract feature to remove a pixel or two and now the matting defringe feature. 

When looking at the image with a black background I don't see a halo/edge, it's only when I see it in the desktop folder, before opening (see screen shot). Any ideas?

Not sure how the OS generates the thumbnails, but I'm guessing that it sees the semi-transparent pixels in the image, is matting them with a white background so that they are fully opaque (leaving the fully transparent pixels alone), creating this white halo, even though the file itself looks correct when viewed in Photoshop

Thanks @BrettN

That's what I would have donr

Your attached PNG is OK.  No halo at all.  

I turned on the bounding box to show that the 'A' has no content outside of what it should have.

I don't know if it is a clue, but the PNG has a transparent border beyond the A.

The bottom line is that the graphic is fine, and has no actual halo.
