Transparent Background, Light Image?


Recommended Posts

I've been lurking around here for quite some time now, but I realized it's time to ask a question of my own instead of looking for similar questions.

I have a light-colored image that I want to make a transparent background of without having any of the jagged white edges and whatnot, to make a signature and avatar and so on. I've tried the magic wand, Alpha Mask, and Alpha Space, none of which have succeeded. As I said, the image itself is very light (the attached image), so it's difficult to achieve what I'm trying to do.

Any suggestions or ideas?

In trying to use the magic wand, there is no mention as to what settings you have tried or if maybe you were using the default settings. Another person awhile ago had an image that was essentially white on white and was able to get the background erased. Have a look here and see if this can't aid you:

If after going through the above you seem to have some "jaggies" around the edges, use the AA Assistant on the image (you may have to do it a couple times). One of the things I often do (especially with a light image) is create a new layer, move it down below the image I'm working on and using the paintbucket, paint that layer black. This permits me to more easily see the outline of the image I'm working on and whether I should apply the AA Assistant to the image again. Once all is well, you can delete the layer with the black.

EDIT:

As you can see from my screenshot, I was able to remove the background. Also, I started using the "Tolerance" at 25% but had to adjust it down in other areas. You can also see that I used the black background method I described above and had to apply the AA Assistant twice to get a favorable result:

Good catch, jim! I honestly wouldn't have thought to check up on that...

Before you do that, though, I would temporarily increase the canvas size by about 4 pixels per dimension. That way, AA's_Assistant won't leave anything stuck to the edges.

Find myself doing this too. (I think it's the first time I've seen it published)

I also find that using feather before AA assistant helps as well.

also if the image you are using is going to be shrunk down by a bit, lets say half size or more then gaussian blur could help you, run it at 2 px then resize the image to half or even smaller if needed.
