automatic unsharp mask

Hello

I do not know if it's possible to do what I have in mind

I use the unsharp mask filter very much

And I created an action to apply the effect

Unfortunately the sharpness is fine for photos of 6000x4000 px

When using smaller or larger photos I have to go to modify the values of the unsharp mask filter

I would like to know if there is a script that, depending on the size of the file, applies the right clarity.

Thank you

You could use if-clauses (or a switch-clause).

But if you think there are »correct« settings for the sharpening depending on image dimensions alone that would be an incorrect assumption.

// 2017, use it at your own risk;

#target photoshop

if (app.documents.length > 0) {

var myDocument = activeDocument;

var originalUnits = app.preferences.rulerUnits;

app.preferences.rulerUnits = Units.PIXELS;

var theWidth = myDocument.width;

var theHeight = myDocument.height;

if (theWidth <= 1000) {unsharpMask (120, 1, 5)};

if (theWidth > 1000 && theWidth <= 2000) {unsharpMask (120, 2, 5)};

if (theWidth > 2000) {unsharpMask (120, 4, 5)};

app.preferences.rulerUnits = originalUnits;

};

////// unsharp mask //////

function unsharpMask (amount, radius, threshold) {

// =======================================================

var idUnsM = charIDToTypeID( "UnsM" );

    var desc2 = new ActionDescriptor();

    var idAmnt = charIDToTypeID( "Amnt" );

    var idPrc = charIDToTypeID( "#Prc" );

    desc2.putUnitDouble( idAmnt, idPrc, amount );

    var idRds = charIDToTypeID( "Rds " );

    var idPxl = charIDToTypeID( "#Pxl" );

    desc2.putUnitDouble( idRds, idPxl, radius );

    var idThsh = charIDToTypeID( "Thsh" );

    desc2.putInteger( idThsh, threshold );

executeAction( idUnsM, desc2, DialogModes.NO);

};
