Scale gaussian blur

Hi there people,
I created a logo in illustrator with 2 gaussian blurs. I have a normal thin path with a stroke of 2px and a gaussian blur applied.
It all looks good, but when I scale the logo real big or small, the gaussian blur doesn't scale equally.
Can you tell me how I can set the layer/blur so it whill be exactly the same in any resolution?
I understand it happens because the gaussian blur is a photoshop non-vector based effect. this way the blur doesn't scale up or down.
is there any other way to get a similair blur in illustrator? (or any other solution)
greets,
jeroen

Hey Folks -- I'm working on CS3 (mac) and we're having the same problem with scaling the gaussian blur. I checked the prefs and made sure "scale strokes and effects" was checked off as an option but it's still not working. Could that be because the original was done as a filter and not an effect? How can you tell which method was used?

AI effects: Feather versus gaussian blur? which is raster or vector?

i`m looking at feathering versus blurring. both in illustrator effect drop down menu.
from what I I understand the blur/gaussian blur under photoshop effects (in illustrator) will pixelate the edge gradation, but the illustrator effect "feather, will keep it vector, is this correct?
from sample here they both look the same to me, and I noticed the feather effect was gaussian blurring the edge anyway to produce its result,,
from what I can see I should be able to make either of these as large as a billboard and they would both still be smooth gradients? or would the gaussian blur result in pixelation unless I had the vector object sized correctly in the document in the first place to suit the billboard.
what I am trying to ask is how do they work,
my take is the AI "feather" will allow resizing of the vector object shape to any size and not be pixelated on print output,
where as the gaussian blur PS effect, you would need to make sure your object is correctly sized on the correct document size to ensure that it prints smoothly.
any feedback is good,....

wildbirdsketch,
actually can I confirm, both produce a raster gradation to soften the edge, so its no longer vector once you apply a blur or feather correct?
It is, but with raster effects.
asking because if I create a blur/feather, I will have to consider the resolution or not as again I`m assuming no because each time I resize the object the effect recalculates itself as necessary to create the right blur and resolution for that size.?
As long as you keep the Effect>Document Raster Effect Settings the same, the resolution of raster effects will remain the same,
and when these vector objects print (in general for AI), i`ve never known, do they print as Vector or does the RIP turn them all into raster anyway?
Indeed.
just confused on this, I`m guessing their only vector while in illustrator, but once going through the printer it will all be raster via the RIP if thats correct,
Indeed.
its just that vector allows you to scale it to the required output size prior to print and have it print crisply without having to focus on resolution or resampling methods correct?
Indeed.

Script to Edit Gaussian Blur Effect

Hello
I have a complex piece of artwork which has to be scaled up by a factor of 10. No problem except the Gaussian Blur Effect will not scale.
Rather than go through each path and edit the blur amount (by a factor of 10) I had hoped I could write a script which would iterate through every path and if it had a Gaussian Blur Effect edit the value.
Looking in the AppleScript dictionary and online I can't see any way of accessing a path's Appearance or Effects.
I would be very grateful for some advice on this before I start the tedious process of manually changing the values.
Regards
Chris

Hello Mark
Thanks for your prompt reply. I thought as much. It's disappointing really.
The select filters will not unfortunately be helpful because the blurs are different so I can't select all blurred items because I don't want to set them all the same and equally I can't pick one and select all with the same blur amount because I don't know if I have changed all of the items.
I've just got my head down and am selecting them all individually and editing them!
Regards
Chris

Gaussian Blur is different when Scaling

Hi Guys,
I have a problem when I scaled one object which has Gaussian Blur effect. Before it is scaled it looks smooth and nice (1st image), however when it is scaled to larger size, the Gaussian Blur does not look the same (2nd image). Please refer to my screen shots for better understanding. Any help and tip is greatly appreciated. Thanks in advance.

David,
Just managing to collect my wits (easier here an hour after midnight).
The Gaussian Blur is fundamentally a Photoshop effect and therefore fails to answer to the Scale Strokes & Effects.
You will need to increase the value as suggested, or you may turn the object into a Symbol before scaling, and then it should behave as you wish.

Transform Effect and Gaussian Blur creates issues

Here is one issue I cannot figure out how to correct. At times, I apply the Distort - Transform effect on a clip to scale up/down, etc,...then the next clip (which I dissolve to) has the Gaussain Blur applied to it. When I apply the blur the previous clip (with the Transform effrect) shifts. I have the Blur effect above the Transform effect in the Effects pannel and it still does not help. I cannot figure out how to stop the clip from shifting.

I recall a similar bug with Gaussian Blur a while back. I winder if that bug is still around.

Layered PSD files getting corrupted when applying a gaussian blur.

A file is created then three layers to keep simple a red square is created using the marquee tool then filled with a colour this is repeated on the next layer with a different colour then the third layer is completely filled with another colour.
The first two layers are selected and scaled then made transparent.
Finally the layer in between layer 3 and layer 1 is selected and a gaussian blur is applied this is when the corruption occurs

After file is corrupted Photoshop has to be closed and re-opened because subsequent files that are opened are corrupted.
This has been reported in CS5 and CS5.5 extensively but not so much in CS6.

Below is the steps that where used to create the corruption in the files.
Gausian Blur corruption in Photoshop
Step 1. Create document with 3 layers + Background.
Step 2. Layer 3 - Create a box (Red)
Step 3. Layer 2 - Create a box (Blue)
Step 4. Layer 1 – Fill layer (Yellow)
Step 5. Select layer 3 & 2 & scale down & press
return
Step 6. Change opacity of layer 1 & 2 to 25%
Step 7. Go to layer 2 and select Gaussian Blur filter
Please Note that the blue & Red Box Have changed
colour.
As I Zoom in and out the corruption gets worse.
Sometimes this corruption dose’nt show up until you have
saved & reopened the file.

Gaussian blur vs smart sharpen

As far as I know, gaussian blur is a spatial convolution filter and smart sharpen is a deconvolution filter.
So I think that they should be opposite of each other when smart sharpen is at the gaussian blur mode.
But we can not remove gaussian blur (applied to a JPEG) with the smart sharpen adjusted for the same radius.
Why are they not opposite to each other?

As a long-term user of USM, I am confused about the function of threshold slider in USM now. Reference says that:
"Drag the Threshold slider or enter a value to determine how different the sharpened pixels must be from the surrounding area before they
are considered edge pixels and sharpened by the filter. For instance, a threshold of 4 affects all pixels that have tonal values that differ by a
value of 4 or more, on a scale of 0 to 255. So, if adjacent pixels have tonal values of 128 and 129, they are not affected."
Look at the following image please:
Initial tone difference is 40 and threshold is set to 30. According to the reference, USM should apply the indicated amount as sharpening here, but there is no change in the tone levels as seen at the info panel.
I think that threshold is working as a fine tuner for the amount slider, it is not functioning as said in the reference.
I would like to learn your thoughts,
Am I missing something?

Creating a symbol from shape with gaussian blur = problem

I am trying to create artwork to map to a globe using the 3D revolve effect...the problem is the shape/layer I'm using to create the "glow" effect (compound path filled with white and a gaussian blur applied):
When I create a symbol out of this, here is the problem (note the "excess" areas on the top and right):
...resulting in this messed up globe...
Doing an outer glow effect instead of gaussian blur results in the same thing (its definitely the blur causing this, deleting the shape fixes the problem). Expanding the shape with the blur results in an image the same size as the bounding box in image 2 above. Any ideas how to address this?
thx

Yep, that did it! (something strange going on now with the longitude/latitude lines going thru India, but I'll work on that later)...Thank you!

Gaussian Blur in Photoshop CS5 Corrupting files

We just got brand new systems at work less than a month ago and this event has happened twice since then. When using Photoshop CS5 Extended and using Gaussian blur the file becomes blocky and all layers as well as their masks become corrupted with these blocks. Can anyone help or is there any advice?
Here are my system specs...

I'm getting this same issue - or a similar one. It seems to only happen when I run the Gaussian blur command, and during the same process in my workflow. It also seems for me to happen when I have made a selection from a layer above that is a smart object.
Let me describe the scenario that I have experienced a couple times in the past week. (BTW I just upgraded to CS5 only a couple weeks ago).
Usually I have a document open with dozens or hundreds of layers. The effect that I am executing when this seems to happen is where I have a group of shapes or placed image smart object layer and I'm creating a shadow layer by making a blank layer below said group or image, making a selection from the above group or image, and then filling the selection in the blank layer with a color - which I then run the Gaussian blur filter on, and afterward warp transform to get my realistic looking shadow effect.
But the problem is in seemingly random instances and on seemingly random documents when I run that Gaussian blur, Photoshop freaks out and craps the bed. And by craps the bed I mean deletes pixel data from multiple layers in my document very randomly, and also generates odd bright colors all throughout the document.
You can see the initial freak out in this screen shot from when I just initially selected the Gaussian blur filter from the menu (but had not yet even clicked "OK"): http://cl.ly/3KTx . The strange thing is that I had just run this series of steps on the above layer which in the screen shot you'll see as "Layer 44", and all was well.
Here's a screen shot showing the file after I closed it out, restarted Photoshop, and opened the file back up: http://cl.ly/3K2C . In case you can't tell, data from several layers all over the file is missing and corrupted.
I'm sure I don't have to explain how exasperating this is, as this represents more than a year's worth of work on a client project, no joke. Fortunately I'm mostly done with the actual site build, but that makes the loss of the artwork files of no less consquence - especially seeing as how I'm not ACTUALLY finished and I did in fact need all of that data to complete the project.
Anyhow, some additional details which may or may not be related to the issue:
- The issue seems to happen randomly. As stated above the same steps did not produce the error just a few minutes before.
- I have had this issue with another file this week where I was doing the same processes on another shape.
- It seems that this is occuring when I make the selection from a layer that is a smart object of some type
- I also noticed artifacts in the weird colors (after I tried running the processes again, so not in the above screenshot) that were actually design elements from an entirely different document that I was working with earlier this evening.
- I have filed a bug report.
Dunno what else to describe, but I hope you guys can get this figured out, seriously. I paid way too much for my upgrade to CS5 to have bugs in key software features corrupt my files thank you.
Also, in regards to my system...

How to batch apply Gaussian blur in Aperture

I find myself applying Gaussian Blur to a lot of our shots via Photoshop CS3.
We keep all our shots in Aperture, so I click the image to edit it in CS3, copy layer, apply gaussian blur and set transparency to 30-40%....
Is there a way to automate this ?

You can set up scripts/actions in PS which will automatically be applied to every image that is opened, but I can't remember how you do it. And it would be applied to every image whether you like it or not...

P.S. Most people are trying to sharpen the images, why blurring?

How to "smooth in" a gaussian blur fx?

Hi there
I would like to know how can I "smooth in" a gaussian blur fx. I recorded a video and needed to add a tittle to
the video and when I add the fx it doesn't fade in smoothly it's like ON and then OFF. Is there a way to make it like
fade in/out a few frames? I'm a novice to FCX growing out of iMovie because needed more finer and powerful
adjustments but still need lots to learn compared to iMovie!!! Any help would be VERY welcomed!!!
THANKS ALL!!!
Serge
PS I have 10.0.9 for FCX

IIt sounds like you want to keyframe the blur to ramp it up. Set a keyframe, button next to the value box, and set the slider to zero. Move later in time where you want the blur to finish increasing and set the slider value to whatever you want. The additional keyframe will be added automatically.

I'm trying to isolate skin with a secondary layer and am successful. I want to blur the skin to reduce blemishes but when doing so the blur and degrain sliders don't seem to have an effect. Can I apply a gaussian blur fx on just that secondary? Can't see

I'm trying to isolate skin with a secondary layer and am successful. I want to blur the skin to reduce blemishes but when doing so the blur and degrain sliders don't seem to have an effect. Can I apply a gaussian blur fx on just that secondary? Can't seem to figure this out. Is there a better way to smooth skin?

Here's an Adobe help page for isolating skin with suggestion on the use of the blur slider also:
https://helpx.adobe.com/speedgrade/using/apply-secondary-color-corrections.html
And here's one of the original creators of Iridas/SpeedGrade, Patrick Palmer, a six minute vid-tut on using secondaries (specifically in CS6 but this hasn't changed):
http://tv.adobe.com/watch/learn-speedgrade-cs6/secondary-color-correction-in-speedgrade-cs 6/
I'd note, the "blur" and "denoise" tools on the Secondary tab are more about smoothing the keying of the secondary ... they apply a bit of blur or de-noising to make the secondary smoother and cover over the odd pixel or three or four that don't "fit" the key of the secondary in the middle of something you're aiming for.
In current SpeedGrade, I'd try using the Guassian Blur (Range) effect, and sample a good range of the skin tones.
And a lot of people use Red Giant's "Cosmo" plug-in over in AfterEffects or Premiere Pro ... it's a tool designed specifically for working skin tones, dealing with blemishes, wrinkles, spots, and such.

What's differences gaussian blur in Photoshop and Premiere?

I would like to ask about the gaussian blur of Photoshop and Premiere.
Normally, in Photoshop it says pixels in radius, but in Premiere it says only blurriness. Does anybody knows the differences of these two? I used Premiere to apply gaussian filter for our clips, but I want to know the value with pixels in radius.
Thanks in advance!

I'm not sure. But you could probably match it up pretty quickly.
Blur an image in Premiere with blurriness 50.
Open the original image and the blurred image in Photoshop, put them together in the same document and set the layer blend mode to "difference".
Then blur the original with Gaussian Blur and change the radius until it matches Premiere's result (image goes black because the 2 layers are the same).
My guess is that the numbers have the same meaning, but someone put a really wrong label on it in Premiere.

How to Gaussian Blur

How do I make a Gaussian blur in LR4 ?
I have tried to mask the area and unsharpen and unclairify but doesn't work.
Thanks, Penni

Generally speaking if you want to simulate a shallow depth of focus effect, a Lens Blur tool of the kind used in Photoshop will look a lot more nearly convincing.
The only truly convincing way - convincing for an expert eye, that is - is (of course) to go ahead and shoot with a shallow depth of focus in the first place .
However where any particular local effect is wanted in LR, and the adjustment brush does not have enough strength to deliver it - you can simply add a second (third, fourth) adjustment brush "pin" applying some more of the same parameter over the top. Quite soon though, it will be apparent how transformation (rather than development) of original picture content calls for a partnering, designed-for-the-job, image editor.

How to put gaussian blur in background of portrait in PSE 8

I have just spent four hours trying to blur the background of a portrait. Should be a simple task but something goes wrong. I make a duplicate layer, but when I try to gaussian blur the layer, it just goes to checkerboard. And the preview screen for gaussian blur goes black. Am I doing something wrong, or is there a glitch with the program?

Hi,
Are you creating two different layers of main object and background... Also make sure that appropriate transparency is porvided in each layer...
