I am getting weird halos around the head of my model?
I had this once on an outdoor pic but currently struggling with a photo where I made the background transparent, then saved it as a jpeg. The resulting JPEG has the white background, with this white halo still there? What am I doing wrong? Driving me bananas. Thanks so much!

Your masking isn't quite 100% transparent.

Make sure your 'transparent' area truly IS 100% transparent.

Looks to me as if you have maybe a 1% opacity setting on those pixels that you call a 'halo'.

Don't quote me on that though....it could be 2%.

If you set up your INFO Panel like this...

info_opacity_A_01.png

...you can constantly check the transparency.

...Thanks Mr Tom!... ...you're right but how do I change this? I also had this with the outdoors photo below, not sure what's going on in the first place?
No worries.

I couldn't say for sure but all you need to do is just delete any pixels in the affected area.
If you can still make a selection around what you want to keep then you could invert that selection and hit 'delete' a couple of times.

That should ensure that any pixels remaining are completely removed.

Without knowing how you made your original selection its difficult to say why you had this issue....just make sure in future that you check the surrounding area with the info panel for transparent pixels that are not visible to the naked eye.

One trick I use is to temporarily apply a drop shadow to a layer with transparency....crank up the settings so its good and dark and any 'stray' transparent pixels will stand out like a baboons bum.

This makes it dead easy to then clean everything up.....then just delete the drop shadow when you're done.

Its not shown in your screen shot but did the problem area have an opacity other than 100%?

Regards.

Thanks Mr Tom!

I had a look at the info panel and it appears you're right but how do I change this?

I also had this with the outdoors photo below, not sure what's going on in the first place?
In your first post's screenshot, I see you've used a mask. If you had one applied on the model layer, maybe the areas around the head aren't 100% black?..... Brush black in the areas to completely hide it.

Or ... if you simply deleted the background, the halo are leftovers - the result of not fully selecting everything in the background. Maybe the result of using Select Color Range or if you created the mask in Mask Mode with a brush at a lower opacity or strength. If so, use the eraser tool to see if it clears the halo.

MrToms add a shadow suggestion will also work for as long as there's enough transparent pixels for the filter to base the shadow from. Play around with the shadow direction angle so you can determine the extent of what and where to delete.

Try his suggestion, too.

I agree with MrT that this appears to be leftover pixels from the masking process. It would help us to know what the original background looked like.

I would like to see your layer mask. You show this by hitting Alt/Option + clicking the layer mask.

Show this version....

And this hit Command/Control + I to invert the selection, show that version....

Hit Command/Control + I to set the layer mask back to normal.

Hit Alt/Option + click the layer mask OR just click on the layers thumbnail to return the layer back to normal.

Although both can, the inverted mask view will show any leftover pixels like this............

Thanks for that!

I have tried selecting with magic wand tool, selection tool etc and then deleting but it still stays. :(

Here are the images with it showing:

Here is another image and it looks like a certain process (see history panel) seemed to cause the halo? Random..?

Also, it seems to always be in the same place?

Thank you!

To be honest it would be much easier to see what's going on if you could upload the PSD file.

The screen shots are great but its not possible to see whats going on just by looking at them.....with this sort of thing you have to do things by the numbers and that means on the original file.

If you can see your way to uploading the PSD file it'll take out all the guesswork.

Again, I totally agree with MrT.

To state the obvious, there's something in your work flow that your doing causing the issue. A PSD would help us to weed it out.

I would start by just turning off layers (and back on) until I find the layer causing the issue. Process of elimination.
