TR's Bokeh Plugin V2.0 (Dec 12, 2014)

[TechnoRobbo]

TechnoRobbo's Bokeh Plugin

a simulation of the Classic photographic effect

due to complexity - slow renders on larger images

higher the threshold the faster it renders.

 

v2.0+ better threshold control

How do I create the middle image with just the circles? And it takes kind of long to create the effect if the image is detailed, but it's a really nice plugin. Thank you!

[TechnoRobbo]

Welsh,

 

I just uploaded v1.1 threshold based on saturation not intensity - gives better color control 

 

Helen,

here's an image created by drawing dots running plugin drawing more dots running plugin again. Maybe that's what you want, The higher you set the threshold the faster it renders.

This one uses my pixel sharpener to give those bright outlines

 

 

 

Weird.  I'd never heard of Bokeh until Monday ... WelshBlue

 

me too!!! I never knew it had a name. I was looking at images of blurs to try and create a simulation and I stumbled on the the name "Bokeh"

 

Super Weird!!!

 

 

... I've been working on a tutorial and gotten this far:

 

 

... I'll hold back on finishing it 

 

Nice,  that's Art.  My plugin's a simulation - a tool. No sense in holding back.

Started with This

 

Ran your plug in to get this:

 

And after a play around with other plug ins I got this:

 

A great plug in with many uses, thank you.

[pdnnoob]

I read "TR's Broken Plugin" and thought huh?

 

Cool!

[TechnoRobbo]

if you don't mind I'll go ahead and post it but gear it towards photo manipulation rather than the conventional sense of image.  Your plug-in will do that ... 

 

Welsh,

 

Heck , I don't mind, that's why I publish my source codes - free knowledge for everyone.

[skullbonz]

I thought a Bokeh was something you smoke weed out of,lol.  

[blackpenny]

I read "TR's Broken Plugin" and thought huh?

 

Cool!

 

Thank God, I'm not the only one!

 

Looks really cool, I'll be playing with it!

[Lloyd]

Thank God, I'm not the only one!

 

Looks really cool, I'll be playing with it!

Make that three of us. I read it first as 'broken' Looks like it could be a good plug-in to explore.

Decent example DrewDale. It looks like a lot of other plug-in's were used to get that final image.

Hey guys,

I'm here looking for some sort of bokeh-plugin. This one comes close to the real stuff, but it still looks a little generic. (Still awesome to have it, and for free, so thanks a lot!)

 

Here's a page I stumbled upon some time ago, gets interesting in the middle and it even has the source code at the bottom of the page:

http://www.cs.ubc.ca/labs/imager/tr/2012/PolynomialOptics/

 

Any chance you could do an effect like this in paint.net?

[TechnoRobbo]

I see Bokeh, Star Filter and lens flares. I have a simulation for Bokeh and my GlamourShot is a star diffusion simulation. I do not have a lens flare but it does exist check the plugins index possibly Madjiks pack

This is an amazing plugin. I was actually wondering what this effect is called like when you use a DLSR, it blurs the background with these fantastic faded circles from a distance. I was a looking for a way to create it artificially. It turns out its called Bokeh. Gaussian blur just doesn't make a blur as good as this.

 

But it renders kinda slow on my computer, even with considerably low resolution and low quality images. I'm using a netbook with Atom processor and 2GBs RAM but many other plugins just render OK with it. Any way this could be made to render faster?

 

Thanks.

I can make it faster but I would have to migrate the code from CodeLab to Visual Studio. I have a couple of other projects right now though.

[Ishi]

Thanks.

 

But I see so much great potential with this plugin. Its one of a kind. Don't you think, it should be under Effects>Blurs section instead of Effect>Photo? And maybe add a little icon for this.

 

We can finally edit pictures taken from a phone camera or a digital camera and make them look like as if they were taken by a DLSR.

[TechnoRobbo]

When I transfer it to VS it will, but I have a lot on my plate right now.

Version 2.0 - adds a progress bar for larger images

Version 2.0 - adds a progress bar for larger images

 

@TechnoRobbo! Thanks so much for sharing. 

[ftlog666]

thank you TR now i can make my own instead of those weird 'images' you see  it

[TechnoRobbo]

Your Welcome Seerose

[bhark]

Thank you ever so much. This looks like fun😊
