TR's Pixel Sharpener Plugin v2.0 (Dec 21, 2014)

[TechnoRobbo]

TechnoRobbo's Pixel Sharpener V2.0

 

This is the real deal.

Use it on that photograph that you thought you messed up.

 

Menu: Effects-> Photo

 

v2.0 adds horizontal and deblurring and larger deblurring range

 

 

 

 

These are actual examples - try it for yourself.

How it Works

 

When you take a digital photograph the lens focuses the light rays from point of detail on your subject onto a pixel on your camera's image sensor.

 

did this on Google Sketchup

 

 

When the your subject appears out of focus the camera has focused the light from a point of detail in front of or behind the sensor in your camera.

 

As you can see from the diagram the pixels around the intended pixel are now polluted by the unfocused light.

 

TR's Pixel Sharpener subtracts the light levels of the adjacent pixels from each pixel then amplify's the level of the pixel back to it's intended brightness.

This effectively removes the light pollution from the image and focus is achieved

 

 

Hope that makes sense.

 

I'm not very good at writing equations but I believe it should look like this

done in Microsoft Equation 3.0

 

where "a" is the current pixel and the "b" series are the immediately adjacent pixels.

Reminds me of this: http://forums.getpaint.net/index.php?/topic/16610-enhance-details-plugin/

BoltBait,

It's not an embosser. It actually removes the adjacent pixels influence.

Try it, I ran a whole bunch of old family pics through it. Blew my mind, and I'm the one who wrote it.

Please show us some results.  A picture paints 1K words - just like your excellent explanation images.

[TechnoRobbo]

EER,

 

I'm not going to post my kids on the internet but I will message them to you.

How is this different from the built-in Sharpen ?

[TechnoRobbo]

RB,

Very different , observe and try

nevermind...i found the "CodeLab" plugin....(I was trying to use Visaul Studio)....derp..

 

Just wanted to change the default value of his plugin..it set to high imo.

It depends on the resolution,but that's why I always publish the source code. Fell free to customize.

Just wanna say thanks for this, I seem to get much better results than the inbuilt sharpen.

Wanted a way to sharpen without going to far and this seems to work great.

Your examples go a little to far for my liking, so below is one of my tests.

It was made by duplicating the original to a new layer, tr sharpen by .25, set blend mode to lighten at 127 opacity, duplicate the sharpened layer again and set to darken 255.

PS...Ever thought of moving all your code to Github so its easier to get?

Thank You,
