Hi all . . .

What if we set the pixel ratio? For example, 1000x1000 pixel is Blur 3 radius pixels. 2000x2000 pixel is blur 6 radius pixels. If it's 1500x1500 pixels, can you make scripts to add how much blur radius... Before clicking the scripts, I'll set the selection with rectangular marquee tools and how many pixels to set.

If performing frequency separation, it is normally done on the entire canvas, not a selection. It can always be masked afterwards.

For one thing a function that takes three arguments should be fed three arguments.

You can use the bounds of the active Selection to determine its width and height and then calculate the Filter-value. 

But what about non-square Selections? How exactly should those influence the target-value?

@c.pfaffenbichler – that's some pretty good voodoo you have there!

 

var theValue = Math.max(theWidth, theHeight) * 0.003;

 

I would have used a whole lot of if/else or other conditionals, which isn't as elegant as your approach!

But does it make sense in this process? 

It would give the same result for a Selection of 1000px x 10px and a Selection of 1000px x 1000px.

Perhaps not!

 

But it makes as much sense as a one size fits all frequency separation based on pixel dimensions rather than unique image content and further editing requirements.

You needn’t use AM-code, DOM-code offers the method applyHighPass (edit: for ArtLayer)

You need to use the ScriptingListener plugin for legacy ExtendScript .jsx code that isn't covered by the legacy DOM... Or UXP batchPlay .psjs code if this isn't in the UXP DOM.

 

EDIT: Here it is in a function for ExtendScript:

 

surfaceBlur(5, 10);

function surfaceBlur(radius, threshold) {
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};
	var descriptor = new ActionDescriptor();
	descriptor.putUnitDouble( s2t( "radius" ), s2t( "pixelsUnit" ), radius );
	descriptor.putInteger( s2t( "threshold" ), threshold );
	executeAction( s2t( "surfaceBlur" ), descriptor, DialogModes.NO );
}

There are no magic numbers, although resolution plays a part, it is all about the level of detail that is required in the HF layer vs. the LF layer.

Yes, gaussian blur radius is not a magic number. . . But in order to separate the image from the low layer and the high layer, we have to adjust the gaussian blur radius again.
For example, in a 4000x6000 pixel image, a close-up face image is blurred by adding a blur radius more than normal when dividing the lw layer vs high layer.
If that 4000x6000 image has a full body image, the blur number should be used a little bit. thank you sir
