Photoshop lens blur: radius 4 = no effect?

Why allow me to specify a radius < 4 if values below that will have no effect?
Try it yourself: set up a Lens Blur with no other effects (brightness, DOF etc) and apply it to a duplicated layer. Now run difference between the two layers - all balck = no difference.
Why can't I get more subtle values below 4?
Same thing with Gaussian blur, though the threshold in that case is .25

Lens Blur in After Effects

In einem Tutorial auf Englisch wird der Effekt "Lens Blur" in After Effects verwendent. In AE CS4 hiess dieser Effekt auf Deutsch "Verwackeln". In der Version von CS5 finde ich den "Verwackeln" Effekt nicht mehr. Wie heisst der "Lens Blur" Effekt im CS5? Oder handelt es sich beim Lens Blus um ein Plugin? Herzlichen Dank für alle nützlichen Tips.

Hi Olli,
"lens blur" übersetzt heisst nach meinem dictionary "Objektiv Unschärfe". Du findest das unter weich/scharfzeichner effekte.
Wenn Du also absichtlich DAS tun willst: "Mit „Verwackeln“ haben Sie die Möglichkeit, jeder Eigenschaft Zufälligkeit in Form von Schwankungen im Zeitverlauf hinzuzufügen." so gibt es dafür diese Adobe Hilfe:

Lens Blur not showing in After Effects CC 2014 Release

Hi,
As I'm new to the After Effects - Video Copilot environment I can't figure this out that why, after having the plugin in the Effects folder I can't see Lens Blur in Effects>Blur and Sharpen>Lens Blur?
I'm working on the project named ParticleDesign which can be viewed here. How can I fix this problem?
I can only see Camera Lens Blur as the only blur effect close to Lens Blur...

There has not been a Lens Blur effect in After Effects for several versions. It was replaced with the Camera Lens Blur effect years ago.

Lens blur effect used on Heroes

Hi, I'm trying to figure out if the effect used so much on Heroes is an in camera effect or just a lens blur/mask? It's kind of a depth of field effect but it has a little harsher blur than you usually see in camera.
For those of you who don't know what I'm talking about, it's usually based around the actor for medium to close up shots. The actor is even sometimes partially blurred. I can't say that I've seen it in action shots so it could easily be a static mask of a lens blur?
Thanks.
Caleb

I know some of the effects in earlier versions of Premiere were Windows only, perhaps this is one of them.

PSE 12 Lens Blur

I tried to the lens blur in PSE12 with the method of selection (exactly like the tutorial) but it doesn't blur the the mask at all........very very little?

Blur with gradient tool / Lens blur

Hi everybody,
I want to make some blur effects like miniature effect or open apperature lens blur.
Currently I'm using the gradient tool with negative sharpness. But I think in 100% zoom, the effect looks a litte bit like on/off. Or is the visible effect just non-linear??
Furthermore it would be create to simulate a lense blur effect in the corners. Currently I have to add at minimum 4 gradients, one in each corner. That's no effective
Otherwise it would be possible to implementate a radial gradient mask additionally to the normal linear gradient. Also a reflected gradient mask, would be useful.
Lightroom is great!!
Thanks,
Leschi

-51 to -100 sharpness is lens blur. It's power is limited by the amount of time it takes to calculate this sort of effect - bigger = longer.

Lens blur problem (depth layer gives a hard edge)

I have rendered out an RGB pass and a depth pass from my 3d package and dropped them into AFX using the lens blur filter to create some depth of field
After juggling with some of the settings I have got the focal distance I want but as you can see from the image I have a hard edge to my RGB layer.
Its as though the LensBlur effect is only working inside the matte of the layer its been applied to.
Ive tried precomping the layers and turning alpha channels off to see if that makes difference but no luck.
Can anyone suggest why the depth pass isnt blurring the edge too?
Thanks

Thanks for your input guys.
I did have the effect applied to the layer so I then precomposed it as suggested which has worked...... (see attachment)
However I now have a new problem!
I actually need the the focus to be reversed, with the background sharp and the foreground blurred.
I tried 'inverting the depth map' in the lens blur settings but it gave me the same problem as before with the hard edges....
Any ideas on how to get the focus working the other way around?

Removing "Lens blur" halos in shallow DOF photo

I'm working on a portait where I want to give it a more shallow DOF (depth of field) than originally shot. In other words: I want to turn the background blurry while the foreground and subject should be sharp. I decided to use the Lens blur filter (Filter-Blur-Lens blur) for this.
Basically I just duplicated the image to a new layer, turned that layer into a smart object, added lens blur to it, then used a gradient filter on the mask in order to make the blur fade away in the front (just like a camera lens wide open would). Finally I used a brush to carefully remove (mask) the blur from the subject, revealing the (unblurred original image) bottom layer.
The problem is that the blurred layer also introduces a "halo" around things which isn't very attractive (see screenshots below). Is there a way to make the background blurry without adding halos? I've tried Gaussian blur as well but the same problem was there. I'm using Photoshop CS4 on a Mac.
Original image
Duplicated layer blurred (lens blur) -notice dark "halo" above hair
Masked to reveal sharp (original) layer for subject. The halo is of course still there. Not very flattering

Mask it ahead of time, using Refine Edge to make a new masked layer showing just the portion of the image you want in the foreground.
Then use the mask to select the subject in the background, expand the selection some, then use Content Aware Fill to remove the subject from the background.
THEN blur the entire background. The results can end up surprisingly believable.
Refine Edge makes it possible to do quite complex subjects...

Disappearing Icons/Controls in Blur Gallery and Lighting Effects Filters

About a month ago (after I downloaded Photoshop 2014 but BEFORE the most recent update); I found that the adjustable tack icon (in Field Blur) and the light icons (in Lighting Effects) have disappeared. I can still adjust their controls but they don't appear on the screen so I'm not sure where exactly they are and thus can't move them. Anyone else had this issue? This has persisted after the most recent update.

Could you please post a screenshot to illustrate the issue?
What are the Performance Preferences?
What have you done for general trouble-shooting so far (restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be of special interest)?

CS 5.5 plug-ins - sans Lens Blur Filter

hello the BASIC Lens Blur filter from AE 5 is NOT showing up in AE 5.5 - and yes its in the correct folder in AE 5.5 but its not a choice in the effects menu
any solution suggestion?

Lens blur is not included in 5.5 as a selectable option.
However, you can add lens blur to a layer in CS5, then open or import the project in CS5.5. The filter will show up and you can copy and paste it to another layer. It's kind of a wonky workaround, but it will work.
I'd love to see a project where the new filter won't do what the old one did. Blur map is the new Depth Map. If you have an example, even WO footage I'd love to take a look at it.

Lens Blur Speed

I have recently upgraded both my computer (from a 2005 G5 to a 2010 Quadcore Mac Pro) and my Photoshop (CS4 to CS5). I've extensively optimized my new Mac Pro to work best with CS5 and in general I'm seeing excellent improvements all around. CS5 is about 5x faster with the new system. The selection and masking tools are an absolutle joy to use as they are not only faster, but are producing profoundly better results.
However, the Lens Blur filter is running at just about the same speed as before. Using the same image and the same mask to drive the blur, I'm getting a time of just under 5 minutes on both machines. You would think even at the most redumentary level, the faster CPU speed would confer some sort of benefit on the new system.
Worse still, whatever is happening with the Lens Blur process on the new system is stalling most other tasks on the machine, preventing me checking e-mail or accessing other programs during the Blur. This was not true on the G5 with CS4. Activity Monitor shows CS5 only using one of four cores (though the task gets broken up into chunks in a seemingly random pattern)
My theory is that this task was able to use both 2.3GHz CPU's in the G5, or at least could leave one free, but it is only able to use one Core, but is somehow tying up the entire processor ont he new 2.8GHz Quadcore.
Old system:
2005 G5 dual 2.3GHz
4GB RAM
OSX 10.4.11
CS4
New system
2010 2.8GHz Quadcore Mac Pro
12GB RAM
OSX 10.6.4
CS5

Thanks for your response. I am using a 1024K tile size and a RAID0 scratch disk. (My understanding was that SSD is not appropriate for scratch.) My previous system does not have the benefit of any optimized disks - in fact, that computer's disk are nearly full, which should slow the performance on the older machine and at least give the illusion of better perfomance on the new one.
Is the scratch disk an issue here if RAM is not full? (I would be surprised if all 12GB were filled by this operation.)
As I said, the general performance has been good, but the Lens Blur filter, even at one core, seems to be awfully slow.

LR/PS - Applying the Lens Blur Filter for Selective Focus | Adobe Evangelists - Julieanne Kost | Adobe TV

In this episode of The Complete Picture, Julieanne Kost shows us how to get great results with the Lens Blur Filter in Adobe Photoshop CS4.
http://adobe.ly/x3bXus

After you make the blur over the full picture, you quickly switch to the gradient panel, but you say it so fast that I don't know what you pressed to get there. It sounds like you say tap the "g" key for gradient. But when I do that, the paint bucket tool appears. Help?

Scrubby sliders in the Lens Blur Filter in PS CC 2014 behaving erratically.

The scrubby sliders in the Lens Blur Filter in PS CC 2014 are behaving erratically. In PS CC no problems. I may be mistaken, but I think I read somewhere that this filter only works on 8bit images.
In PS CC it works on 16bit, and in PS CC 2014 (no third-party plugins) nothing works. Could this have something to do with the Graphic Card, or Cache Levels? All advice appreciated.

Sorry, no solution to the problem, but a confirmation. I do have the same problem (Intuos Pro and Pen & Touch) showing the problem with ACR 8.5 and Photoshop (2014, CC and 6, these were updated with ACR 8.5) . No such problem before ACR 8.5 and no problem with LR 5.5 (also containing ACR 8.5).
I hope there will be a solution from Adobe soon, since sems to be caused by the ACR update.
Windows 8.1 in my case and latest Wacom Intuos driver installed.

Maya z Depth Lens Blur in AE CS5 Problem

Hello,
The lens blur effect with a z depth file mapped in the depth map layer does not seem to work in CS5. Although when I use lens blur in CS4 with the same file, it works. Is there a solution for this?
My z depth file is targa extension and rendered in Maya.
Any help would be greatly appreciated, thanks!

I just tried it, and it works for me. If you upload your project, I can take a look.

Crummy Camera Lens Blur CS6

The Camera Lens Blur effect that came with AE CS 5.5 and CS 6 doesn't look nearly as good as the old Lens Blur effect that came with CS 5; it's pretty much unusable for my purposes. Foreground elements that should be sharp render sharp, but with a blurry halo around them. The old Camera Lens blur does not exhibit this behavior, nor the Frischluft Depth of Field plugin.
Here's an image showing the depth map and how the three plugins render it:
CameraLensBlur.png
The images are composited from 16-bit PNGs rendered out of Cinema 4D. There's a nasty halo visible around the foreground particle in the upper left in the CS6 Camera Lens Blur version. I saved the old Lens Blur effect as a preset out of a CS5 project and am, fortunately, still able to use that approach in CS6 since the "improved" version of the plugin looks pretty crummy (I skipped AE CS5.5). As a test I installed the demo of Frishluft's Lenscare plugins, and after inverting the depth buffer in the plugin I got a good result.
The "new" Camera Lens Blur is acting like the Compound Blur effect. Foreground elements appear sharp but with a blurry halo since the entire "background" is being blurred, creating a blurred ghost of the foreground element. The old Lens Blur effect was very slow, but it did work.
Anyone know how to make this new "improved" Camera Lens Blur look like the other plugins? I've posted a zipped file with the image and depth map in a small AE CS6 project here if anyone here would care to check my settings. Maybe I'm missing somthing.

Thank you.

It's been now more than 2 years now that Shawn referred to you this "bug". Thing that I doubt to be a bug. However, after 2 years now, and being on CC 2014.2, this is still ugly when using a depth map. The bokeh is nice, I give you that. But you clearly can't use it with a Dmap. I know it's pretty useless to tell you things that you already know, either make a bug report. It's clear now that it won't get any update.
And as someone here said, if you can't/don't wonna fix it, why can't you simply pack the old Lens Blur from CS5 as an obsolete effect ? Or let's go crazy, just buy the Frischluft (Dat name...) blur which works and pack it.
I would love, of course, to hear from you that you're on it and that a new release is coming soon... Anyway.
Just to remind you, here some pictures of what we are experiencing with your Lens Blur using a depth map.
Halo around the lens on the middle until the screw top right... and cannot be fixed by any way with the focal distance. But yes, the bokeh is really nice.
And here with the Frischluft
It simply works.
You could say then, why am I not buying it ? I'm considering it a lot now.
