Chris Cox: Fade a gaussian blur on a layer with a mask, who should I thank?

I remember in the past that it was impossible to fade a gaussian blur if it was applied on a layer with a layer mask with the link icon active, as the blur also affected the mask. (some sharpen filters also affect both layer and mask)
Now, even in Ps 13.0.1.3, I notice that it is possible to fade, both the layer and mask using the fade function.
I'm gladly surprised it had been implemented, as I felt reluctancy to do it in the past when I mentionned the issue.
It now makes a more natural and discoverable workflow.
Thanks to whoever implemented it, or corrected that bug according on how it is seen!

Not sure who made that change.

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.

Reproduce Unsharp Mask Using Gaussian Blur

Hello,
I know the effect of Unsharp Mask can be achieved using Gaussian Blur and Blending Mode only.
Given a layer 'L' (The original) its USM(L, Amount - 100, Radius - 10, Threshold - 0) is given by:
GBL = GB(L, Radius - 10) - Gaussian Blur.
Difference = L - BGL.
USM = L + Difference.
I made it using 'Image Apply' and Gaussian Blur yet the result is different.
Does Photoshop uses different method?
How can the accurate result be achieved?

Hi Chris,
All I did was as follwoing:
1. Created black image in 32 Bit Mode (RGB Mode so numbers will be the same in MATLAB).
2. Applied GB with Radius 3.
3. Saved as 32 bit TIF.
4. Loaded at MATLAB using imread.
5. Extracted the first channel (They aer all the same).
The result is up.
Something went wrong with the numbers.
Anyhow, how come the result of my classic Gaussian Kernel are so different from Photoshop's?
Here are the example:
This is the GB Kernel of Photoshop for Radius = Sigma = 2:
Here is the GB Kernel of a classic GB using STD of 2 and support of size [11, 11] (Just like photoshop):
And here is the difference:
As you can see, it is very noticeable difference.
The blur using the classic kernel is much harsher.
Moreover, Using the classic kernel trying to replicate USM ( USM(O) = O + 2(O - B) )yields something completely different.
What am I missing here?
Thank You.
P.S.
Well, I'm just playing for fun, so I don't have "Run Time" limitations :-).

Banding after applying Gaussian blur

Hey all.
I'm working with a project in FCP7 running Lion. What im trying to do is add a gaussian blur with a light ray effect for the end of a song. It slowly blurs up and the light rays add a glow. Fades.
The video quality i'm working with is very good, so I don't believe there should be any problem applying these effects. When they are applied though, i get a banding effect which i really don't want to be there.
Still seconds before the effects begin to keyframe into existence
Still once the effects are being applied. It's a bit hard to see because the image was resized to be smaller. But if you look you can still see the banding around the brighter areas. The banding occurs after the Gaussian Blur is applied, so that seems to be the root cause.
Anyone have any ideas of how I can solve this? Footage is 1920x1080i Pro

That's the first thing that came to my mind...the order. I tried that and it did no good. I'll go back to that part of the project and see if it's still doing it. I added a directional blur and it worked. HMMM...

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.

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?

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.

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.

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

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...

Gaussian blur does not blur all the way creating a weird box

hi when i apply a gaussian blur to an object it is confined within a box....anyway to fix this?
thanks

Yes in the Document raster effects setting under Effects there is a input filed that says Add (pixel input field) Around Object.
change that to something like 60 pixels or higher the is no preview of it but after hitting ok it will be smoother like the screen shot.
I got it to preview by reopening the dialog after already applying the new setting. The setting is sticky so it looks like it was alsopreviewed.
this tip is thanks to one of Mordy Goldings blogs!

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.
