Diffuse Glow filter problem.

[Garry S]

Hi everyone,

This is my first post here and I'm hoping someone can help me out! I'm try to add a Diffuse Glow filter to an image and it's not working as expected. When I increase the Glow Amount slider, the high lights in the image turn BLACK, shouldn't they get brighter? This happens with all images JEPG's, TIFF's and PSD's with layers or not. I'm running PS7 on a PC. What am I missing? Thanks in advance for your help!

Welcome to the community Garry. [excited]

it's not working as expected

I think you're 'expecting' the wrong result here. Albeit i think the name of this filter is a tad fluffy or misleading, it does just what it says: diffuses glow (highlights). The results you're getting are exactly what it's supposed to do.

What's the effect you're after Garry? A glow effect? If so, you're using the wrong filter here... use "Outer Glow", "Inner Glow" (Layer Blend Effects), or "Neon Glow" (Filter/Artistic/Neon Glow).

The Diffuse Glow filter sprays a coat of dithered, background-colored pixels onto the image. Sounds as though your background color is set to black.

Oh, let me echo... Welcome to the forums Garry S.

Sorry, but I'm confused now Mark, because Garry is saying that he's getting black and I don't think that this is what the filter is supposed to do;

When I increase the Glow Amount slider, the high lights in the image turn BLACK, shouldn't they get brighter?

This is how the effect should look like (Welles, forgive me for stealing your Big Berta )

I'd like to thank everyone for replies!

Welles hit the nail on the head, I must have had the background color set to black. I never knew that about "diffuse glow" spraying the background color. Something new to file away!

Thanks also for the warm welcome!

Haw! That's one of my favorites of the stock photos which ships in the Goodies folder on the Photoshop install disc. Pretty silly picture!

I agree with your results Joe. I think my lack of sleep lately has my brains in a scramble. [confused] I was thinking of something completely different, hehe. Good grief. :\

Sorry for any confusion Garry.

PS: Seth's been really sick the past 3-4 days... haven't had much sleep. [sleepy] Sorry about the misinformation guys.

Yeah, that's it Welles! I was only testing with a black foreground color which didn't change anything of course, my mistake :\

Welcome to the Forum Garry S...!
I?ll just add something here:
This filter is quite handy when used in inverse colors [ctrl+I] to add
more contrast, and in normal mode [like shown above]
to reduce surface imperfections and smooth the image. [try fading it at different modes by pressing ctrl+F and changing the blend mode & opacity...]
hope this helps [excited]
