Hello everyone!

How can i make frosted glass effect like a independent layer, which i can use with any picture. It should look like smart object with smart filter, but i won't convert every picture to smart object, because my psd documend include many picture. Anyway i will be able to use this filter on any place for every picture.

Thank you ...

This seems rather simple, unless I missed something so I'm not sure why people are saying it can't be done. Make a cool looking frosted glass effect with methods others mentioned above but make sure the background is transparent and the layer's white areas are blank, not actually white. Then, save it as a PNG-24 file with transparency. Those can handle variable transparency so for any future projects you want to overlay it on, just open that PNG file, select all, copy, and paste it overtop the other file as the top layer. If you can't end up with anything other than an image with a bunch of white instead of mostly transparent, you can just do everything I said previously but then change the layer blending method to overlay or possibly others.

I seem to expect something different than you from a »frosted glass«-effect, namely it affecting the underlying image in more ways than brightness, color or blending with other pixel content.

But as the OP has not provided an example of what they expect your approach might fit their expectations after all.

hello,

I found this topic while searching for a way to do this exactely but with Adobe Fireworks, anyways, can you tell me please how to add that layer on any image using Photoshop or Fireworks (if possible) please?

Thanks all for replying! And sorry for my language..:)

c.pfaffenbichler ,R.Kelly ...yes i may many layers, but i've big poster, and i can't merge and convert all layers, and i want moving this fragment of frosted glass on all surface of the poster.

Noel But it's not hard for Adobe to make some tools like a Adjustment layer, simple layer with some filters, which applying effect for layers under itself.

You would appear to be wrong.

As mentioned above Adjustment Layers work pixel for pixel and can therefore operate relatively fast.

Filters can produce results for each pixel that are dependent on huge numbers of other pixels and are therefore more calculation-intensive. (Edit: Or rather »can be«, naturally a Filter can also operate on a pixel by pixel basis.)

For heaven's sake, man!

I've explicitly stated that I do not think that GPUs are a panacea. I used the damned word PANACEA when stating that I do not regard GPUs as a panacea.

How can I make it any clearer that I do not think GPUs are a panacea?

Sorry I used the word panacea. No accusations were intended on my part.

It occurs to me that if Photoshop were designed from the ground up today things would likely be done differently than they are (and which probably can't be practically changed without doing that ground up rewrite).

An anecdote: I was just doing some testing on one of my plug-ins with a preset that maxes out all controls to do a stress test. This embodies a large number of operations multiplied by a huge number of pixels, just as I mentioned above.

The GPU displayed the preview with the (tens of thousands of) effects the plug-in generated rendered on top of the original image in just a few seconds. The screen was basically covered. Not interactive, but not unusably slow.

When I hit [OK] to commit the effects back to the image, the plug-in switches to using the CPUs (all cores simultaneously, of which I have 8) to render the effects, since they're done in a bit higher accuracy than what's done for the preview. That's been running now, pushing a progress bar across and speeding up my cooling fans, for about 5 minutes. It's only a small percentage of the way through.

For graphics tasks specifically suited to GPU operations, yes, GPUs can be hugely faster than CPUs. But let me tell you, it weren't no easy job to make it work like this. My version 1 of the plug-in did everything in the CPU, and it became clear that while it was acceptable when a fairly small number of effects were generated, people would expect more. The task of porting the plug-in to use OpenGL / shaders / etc. was literally about 1.5 man-years, just to make it do the same things it did before, but GPU-accelerated. Part of that was development of a new framework which can be re-used, but part of it was simply reorganizing the task to be GPU-compatible, which would need to be repeated for another GPU-based development.

The short answer is that you can't, at least not exactly as you've stated. That said, there's no reason to think that a filter or some other series of steps can't be found or assigned to a function key that would allow you to create the effect easily on whatever image document you have open.

It sounds, though, like what you're hoping for is some kind of magic mixture of layer contents, blending mode, and layer styles that will give you the effect when that layer is pasted over the top of anything else, and I don't believe that's possible.

Basically you can’t (if you and I have similar assumptions on what the effect should look like, posting an example might help clarify).

Adjustment Layers affect each pixel on its own, so I think at least one Filter application is necessary.

Your reasoning for not using a Smart Filter seems unclear to me; if by »many pictures« you mean many Layers those could be converted to one SO.

If the Filter>Distort>Glass gives the effect you want, you can use Layer>Smart Objects>Replace Contents to insert a different photo

while keeping the effect.
