Deleting Photoshop History Log in CS4?

[S. Levy]

Good Morning Forum Members,

I was wondering how to delete the history log of what was done in Photoshop CS4 from the metadata of an image?

Have a Good Day,

You have 2 practical options. The 1st is to open your file, Select All, Copy, New Document, Paste. This will create a new copy of your image but you will lose ALL of the metadata.
2nd option, is to use a Hex Editor, open the file, go to the section with the History tab info, and then just delete it / replace it with blanks (screenshot attached).

A better option would be to use ExifTool to remove the data..

Or use a Bridge script IE:

#target bridge
clearHistory = {}; 
clearHistory.execute = function(){
  var sels = app.document.selections;
  for (var i = 0; i < sels.length; i++){  
      var md = sels[i].synchronousMetadata;
     md.namespace = "http://ns.adobe.com/photoshop/1.0/";
     md.History = " ";
  } 
} 
if (BridgeTalk.appName == "bridge"){ 
  var menu = MenuElement.create( "command", "Clear history in Metadata", "at the end of Tools"); 
  menu.onSelect = clearHistory.execute; 
}
