I’ve been trying to get the "Gaussian Glow" effect that Photoshop 3 or 4 had as a filter. I have been doing the following:
1-make a duplicate layer
2- use Gaussian Blur on original layer
3- make duplicate layer 50-60% opaque
4- get frustrated

It works a little but isn’t as good as the old filter.
Any suggestions?
Thanks

Instead of adjusting the opacity (is that a word?) try using a mask instead – you’ll have better control over what will show through as blurred or not. Start off with using gradients as the mask.

Hi, this technique works very well but only on linear image data.

To experiment, dowload this profile package:
http://www.aim-dtp.net/aim/download/aim_profiles.zip and extract the profiles to your /color directory where all the other profiles are.

Then open the image, convert it to the AIM-RGB profile (using Image/ModeConvertProfile) and then do the GG steps.

I don’t know the filter to which you refer but it sounds to me that you’re after what I know as the "Penthouse Blur" effect. The steps you’ve outlined are almost right for that effect except for one thing. You have duplicated the entire layer. Try duplicating the highlight values only ( ctrl-alt-tilde; ctrl-c; ctrl-v). Apply gaussian Blur on the duplicated highlight layer and adjust opacity. By fooling around with the blur setting and the opacity setting you can get a lot of control. I think the effect looks better also if you add a brightness/contrast adjustment layer and boost the brightness of the highlight layer (only).

Another option is to set blur and opacity at maximum acceptable values, merge that with the original and set the new picture to be the History state. Using the history pallette return to the pre-modified version of your original and using the hisrory brush, paint the blurred version in however you want. Try setting the Histroy brush to 40-50% and use multiple brushstrokes until you get the effect you’re looking for.

Works great for portraits but there’s no reason you can’t apply these techniques anywhere you want creative blur.

Have fun

One filter I’ve been using alot the past couple years has been KPT 6 Equalizer. You can shape the sharpness or bluriness just as you would shape the sound on an audio graphic equalizer for your stereo. Thus, you can blur or sharpen within specific parameters (i.e., 256 step greyscale is divided into 9 sliders).

Following are a few examples of some KPT equalizer blur / sharpen effects:

If you’re looking for more of a glow, the following photos used KPT 3 Gaussian Electrify:
