Halo when using Gaussian Blur

[chris-p]

There must be something in your Flickr settings that is re-sizing the pictures. What do you use to upload?

You can delete by clicking on the "organize & create" tab, dragging the photos you want to delete into the selection and then choosing delete from the "edit photos" menu.

Another way of doing a blur, is to use Median - It's under Noise in CS4 and I guess in Elements.

One of the advantages is that the colours bleed into each other less.

Worth a try, I would say.

Chris, I am using Flickr itself to upload, so there should be no reason for the resize. In the mean time, I will try one or two other methods/settings. I first noticed this when the image to blur from the DCM CD tutorial. The poor horse looked as it its ears had developed additional shadows of their own.

Dunno why it's resizing as they're a decent size on Flickr...



I can see the haloing on Flickr. This is happening because Gaussian blurring smudges the pixels together so it's dragging the white pixels from the petals into the background.

What I would try would be to select the flowers themselves, feather your selection (this will feather "outwards from the flowers" and then invert it. Tjat way the selection "fades away" as it gets closer to the flowers. Then try blurring that.
If you do it the other way round (that is, you select the background and feather it) you will feather into the flowers. It's difficult to explain - does that sort of make sense?!

That is how this came about. I selected the flowers, then inverted the selection. But thanks for all the advice, I will try certain other suggestions this weekend. Something has to work
