P: "smart" watermark to include data (location/name/date/lens/camera - EXIF/metadata etc.)

This can be done with a script embedded in an Action in Photoshop. I currently have a script which processes the filename and then feeds that to an action which adds a text layer to images.

I've been needing this for several years as well.  It's no fun.  Watermarks for published folders with variables would be insanely useful.

Add original file numbers to watermarks. Very hard to discuss selections with clients without visible file numbers.

Hello Adobe STAFF !

 I really can’t understand why you refuse (for 4 years !!!) to implement the possibility to use the EXIF tokens in the smart watermark ???

In Lightroom I can program the file name by using special inserts for template {Date (Month DD, YYYY) »}. I propose to implement this feature for watermarks in later versions? 

you can do this with watermark pro, unfortunately not in LR or Bridge or anything (as far as I know...)

I would love to see the ability to export photos in the library module with a watermark of the filename.

I would love for a feature to be not just exporting with watermark, but allow for that watermark to be dynamic -- some keyword, filename, shutter speed/aperture, etc.  

Watermark Pro does this, outside of LR, but having the feature to export, within LR, small JPEGS with the filename or some other identifying information, would help clients and customers pick the images they like.  We can then go back, just search for that keyword and put them up.  

I'd like the ability to use "tags" in my watermarking text. For example, I currently have to create separate watermarks for copyrighting my photos depending on the dates of the photos. e.g., "Copyright 2013 Jeff B", "Copyright 2014 Jeff B", etc.

I'd like to just use a metadata tag (e.g, "Copyright {capture date year} Jeff B.", or "{Copyright}") in the watermark text so that LR automatically fills it in from the metadata fields.

That way I only need to concentrate on how the copyright looks, not so much on what the text says.
