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 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.

Any suggestions on how to remove an "aura" from around a selection in an image? I shoot pictures at rodeos. To make the rider stand out, I create a mask around the rider and then blur the background with Gaussian Blur. This results in a noticeable blur around the outside of the selection. I have tried using Feathering as well as other Refine Edge Tools. The only thing that works is to go around the edge with the Clone Tool. This is time consuming and not totally successful. So, my two big questions are: (1) Is there a better (simpler) way to avoid the aura? and (2) If not, is there a way to remove the aura that is simpler??
Thanks in Advance,

Sorry, what with the long title I had neglected the body of the message and your statement
The only thing that works is to go around the edge with the Clone Tool. This is time consuming and not totally successful.
seems to answer my first question.
Did you do that before or after blurring?
Have you alternatively tried using Content Aware Fill?

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...

How do I get rid of the banding I see in Ai's gaussian blur?

There's banding in the gaussian blur, in Ai.
I'm new to Ai. I created a logo in INKSCAPE, (an open-source free vector program), and the gaussian blur worked fine. But the people that will carry the logo to the next step, use Ai. When I send svg files, (or other types of files), from INKSCAPE, the blur didn't carry over. So I'm trying Ai now... and I'm pretty upset. Do you have a work-around for this?
I was directed here from a survey I was asked to take part in by Adobe. The survey window gave me the impression I would be talking to the company... but I tend not to believe that!
When I tried to contact Adobe regarding the banding problem, I was only directed to the forum. I was already there... and now I wanted to talk to the company.

Try increasing the raster effect resolution to 300 - Effects menu > Document Raster Effects Settings...
If that does not solve your banding issue, post the screenshot and sample file and little more detail on what you are doing.

How to avoid darker color behind a gaussian blur effect?

I have used the effect gaussian blur with black text on top to make a logo.
My problem occures when I try to place the file on a coloured background e.g. a photo and print it. A darker colored area appears behind the gaussian blur. The logo is to be used by others and hence I would like to keep it a vector/illustrator file (not a pixelated photoshop file).
- I have saved it as an ai
- I have all the artwork in one layer
- I have tried object > flatten transparency (but then the area turns white)
- I have tried effect > Document raster effects settings (resolution 1200 dpi / add 35,28 mm around object)

- I use Illustrator CC v. 17.1.0. 64-bit
- the file is cmyk and I only use process colors
- the line is 8 pt and effect is applied with 8 px blur
- everything else in the document is outlines and some text and lines are crossing the blurred object
- color settings: European coated offset ECI
I hope I haven't missed anything. The logo is not launched, but I have enclosed I photo file that is similar and where the same problem occur. The file is placed in InDesign on a blue square and printed from InDesign to a OKIC8660 laser printer.
The light blue to the left is the correct color. The darker blue is not supposed to happen. The yellow is where the gaussian blur is applied.

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.

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.

Gaussian Blur Problem

Hi there
I am having trouble getting the gaussian blur to work properly.
I have an image that is split up into layers using photoshop and I am trying to blur one of the layers. The only problem is that I am getting a white halo round the image as it blurs. My image is a colour image with black lines round it. It is as if the colour is seeping out underneath the black lines as it blurs, even though it's all on the same layer.
The blur does exactly what I want in photoshop, but in Final Cut I have this annoying problem. I can't do the blur ahead of time as I need to animate the blur.
I can't even begin to tell you how amazingly urgent this problem is.
Cheers

OK. I see the problem you have with white bleeding in.
Here's a different approach:
Click the film frame icon with the A on it at the bottom right of your Viewer.
Choose Matte > Color. Go to the Controls tab and set the color you want.
Press F9 to insert edit or drag to the Canvas.
Open the Effects tab in the Viewer. Video Generators > Shapes > Circle. Press F12 to superimpose on V2 in your Timeline.
Go to the film frame icon again and choose Slug. Switch the source/destination patch button to V2
Press F12 to superimpose on V3. Right click the Slug clip on your Timeline. Go to Composite mode > Travel Matte Luma.
Click the Shape clip to send it to the Viewer. Use the Softness contols to keyframe your blur effect .
My result using the above method:
This took about 30 seconds to set up.

Gaussian Blur

Hi folks!
I am trying to understand gaussian blur, but can't get it to work how I imagined.
I have a square let us say 200x200 and have added a fill. When I try to apply gaussian blur it stll leaves square edges:
OK! If I drastically reduce the size of the square to say 75x75 - then the problem goes away....
The second image looks square only because of editing it in paint...lol
The problem seems solved; but if I enlarge my square with the applied gaussian blur - then it leaves square edges again.This causes problems when enlarging objects.
Is there a way around this problem?
bookie56

What actually happens is Illustrator creates a mask larger than the original object, then applies the blur within the mask.
You can control the size of the mask to a degree via Effect > Document Raster Effects Settings.
If your blur is greater than the area added for the mask, you get hard edges or you start seeing corners peek out around the blur.

Gaussian Blur issues

I am having dificulty with Gaussian Blur. I created a selection outline in an image and then filled it with black. I then selected Gaussian Blurr from the Filter Menu a set the radius to 100 and then deselected my previous selection. In CS5 the edges faded into the backgroud image however in CS6 the outline of the previous selection was still visible and the Gaussian Blur did not blend the selection as expected. Even ramping the radius up did not solve the issue as the outline still remained visible. how do i resolve this issue in CS6?
Thanks

Thanks for the responses. I was working along with a tutorial (the first screen shot is of the result that was achieved in the tutorial). I made the mistake of leaving the selection in place when I applied the Gaussian Blur and so i got the result shown in the second image. I only realised this after reading your comments and trying it again. Thanks for your help.

Gaussian Blur displays smaller in CS4

I'm using Mac OSX and have just upgraded to CS4, from Illustrator 10. Our house style is a gaussian blur of 10 pixels, but it doesn't display correctly in CS4 - it's much thinner. I've had this problem before and just exported from CS4 then created the blur in Illustrator 10. On Wednesday last week I tried CS4 again and the blurs displayed at the correct size, then on Friday afternoon (I had used the blur tool successfully in the morning) it started making the blurs too thin again.
It's set to 100% on all the different projects with 10 pixel blur, so why are my gaussian blurs thinner in some and not others in CS4, but all the correct width in Illustrator 10?
This is really frustrating as it would be such a waste of money not to be able to use CS4, and have to go back to Illustrator 10.

Thank you so much! I didn't even know it displayed rasterised effects in different resolutions. I checked Illustrator 10, which was set to 72 dpi and changed it on CS4 so now my blurs are all the right size.
You have no idea how grateful I am. Thank you!

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.
