Is there a way yet to save a picture without metadata?

In Safe for Web you can choose to excluded all metadata and there seem to be

scripts that can strip the metadata of files, if you have only a few you can

copy past the file to a new one and that strips also all metadata (open a

file, cmda / Cmdc / cmd n/ cmdv and flatten the new file to one layer.)

If not, why not?

In general metadata are very useful for various reasons and other

applications can benefit from metadata also.

Not many people have the need for such a method hence such a feature will

not be implemented until many user request for it

I'm dismayed that Bridge -- which was created to help manage your photos -- cannot do the simple task of clearing all metadata.

As professionals we are fully aware that metadata can be very useful. But you said @Omke_Oudeman, "so many photographers so many workflows".

Not all photos I take are for clients -- there are several use cases for clearing all metadata, since there are many general practical needs for photos that I send to various parties that I don't want to know details about me, my equipment, my location, etc. And I'm not even thinking about generally public cases like social media.

Further, since metadata manipulation is already a part of the product, it can't be a huge ask to simply clear it all. At least for a couple major file types.

You really don't want to clear out ALL metadata, and what you can remove depends on file format and application. EXIFTool can remove the most but even it doesn't touch everything. However, fearmongering isn't helpful either. Its trivial to remove most identifying metadata (or you could just maybe, I dunno, not add it in the first place?)

Use a script, or Save for Web, or manually, or use EXIFTool.

It's possible to remove all the metadata in bridge using a script, this should work on most file types except some raw files.

Using ExtendScript Toolkit copy and paste the code into a new window, start Bridge - Edit - Preferences - Startup Scripts, click the "Reveal" button. This will open the folder that the script should be placed. Once that has been done close and restart Bridge and accept the new script.

To use select the documents in Bridge then "Mouse Control/Click menu" select "Remove XMP data"


#target bridge  
if( BridgeTalk.appName == "bridge" ) { 
removeXMPDAT = new MenuElement("command", "Remove XMP data", "at the end of Thumbnail");
}
removeXMPDAT.onSelect = function () {
   removeXMPData();
   }
function removeXMPData(){
if( xmpLib == undefined ) {
  if( Folder.fs == "Windows" ){
   var pathToLib = Folder.startup.fsName + "/AdobeXMPScript.dll";
  } else {
   var pathToLib = Folder.startup.fsName + "/AdobeXMPScript.framework";
  }
  var libfile = new File( pathToLib );
  var xmpLib = new ExternalObject("lib:" + pathToLib );
}
var sels = app.document.selections;
for (var a in sels){
var thumb = app.document.selections;
  var md = thumb.synchronousMetadata; 
  var xmp = new XMPMeta(md.serialize());
        try{
        ...

Wow Paul; you are helpful.  Thanks

and in answer to the other note: I cannot possibly see why when people distribute files, for print for example, they would want to distribute personal data, like camera serial number to strangers.

I cannot possibly see why when people distribute files, for print for example,

they would want to distribute personal data, like camera serial number to

strangers.

To speak personally I really have no problem with that whatsoever, and also

as a professional photographer I have no problem that my clients can see the

other information also. There is nothing I wish to hide and there will be

very less clients that will look in to that information, they probably don't

even know it is there...

And stripping metadata from files while distributing means also stripping

copyright info and IPTC for description etc. That really sounds as horror to

me!!

But as said, that is personal, and the metadata with e.g. serial number

gives me the opportunity to filter all files taken with that camera in a

very easy way.

I often have stated: so many photographers so many workflows. But makes it

very hard for any vendor to fulfill all the wishes there are for

applications.

Hi,

I see your point. Maybe I am (and have been) being foolish.

Hi Paul,

 

Hello from 2020! I've followed your steps to a T, but Bridge is telling me that something is wrong with the script file. Do I copy every single line of text in what you pasted? Including the ellipses at the end? 

 

Once that's done successfully, what does the "Mouse Control/Click menu" mean exactly? Right-click and look in the menu that pops up? 

 

I hope you're well all these years later. 

 

Thank you,

 

Kelsey

I tested the previous two scripts in Bridge 2020 and they both still work. The first script appears in the contextual menu (right-click) while the second script appears in the main Tools menu.

 

Keep in mind that there are other metadata types in files which are not XMP based so may remain after running these scripts.

Thanks!  I used the second script to delete all the metadata, then I imported the correct metadata in from a similar image.  Then I tried adding more keywords to the file and it did not go black as before.  So this fixed the problem.  I had never ran a script before.  Thanks for the documentation on how to do that, and for the fix!

I stumbled over this old post, so just in case somebody else is asking the same... The following script is for Photoshop, not Bridge.
