Need help with diffusion technique

I need a certain effect for a job that I am shooting this week. I have seen it a number of places and can only describe it as the rough equivalent to englarger diffusion in the old days where hard dark edges bleed into lighter areas. The best image example that I can present in a pinch are images by Philip Warner (aka Lithium Picnic)

Like http://rwboyer.com/tartan4.jpg

I have been driving myself crazy in PS trying to reproduce this effect.

Any help would be greatly appreciated.

Please, no conjecture. I have tried a bunch of stuff that I thought might work and have not gotten there. If you know how to do it great. If you have a guess please try it on an image first and then let me know if you can.

Thanks

RB

Re: Need help with diffusion technique

Been there done that, tried everything I could think of. As I mentioned please don't speculate, try it, if you get results then by all means post them.

Re: Need help with diffusion technique

I used Diffuse Vignette without a selection.. filter set available here

You want no conjecture but it is sort of difficult to look into your minds eye and see your vision without a good sample to go on and especially when the sample you provided (which to me looks like a surface blur) is not what you want..
Anyway I think this looks pretty close to what you get from a opal glass

Thanks,

What I am looking for is not the vignette, Look at the sample closely where the dark edges of the clothing hit the lighter background (most apparent in the lower left of the image) can you see the subtle bleed of the dark wardrobe into the background? That is what I am talking about.

LOL, There is no vignette in the sample provided (No selection=no vignette)

Do you want the whole image affected or just the edges? Because on the low resolution sample provided these old eyes SEE NOTHING!

Re: Need help with diffusion technique

I have an action set that might help. You can look at the steps in the actions to see how they work.

http://www.thelightsrightstudio.com/TLRDiffuseGlows.htm

It makes diffuse glows, high key glows, low key glows, soft dreamy effects, etc.

Cheers,

Mitch
