How to add words in the description field on multiple selected photos without deleting previously inserted parts

[Stephen Marsh]

@bersani_4639 

Unlike Keywords/Subject, Description is a single string of text, so we can't append an item to a list of multiple entries.

This requires a Find/Replace in the Description metadata, which can be performed via a custom script.

Can you provide a before and after example of the edit you would like to perform?

[Stephen Marsh]

The following script from Paul Riggott can find/replace in the Description:

https://github.com/Paul-Riggott/PS-Scripts/blob/master/Find%20and%20Replace.jsx

P.S. As this is an old script, the following version has been edited with cosmetic GUI updates for later versions of Bridge:

Try the script on copies of the original images to find/replace the text.

[bersani_4639]

I don't think I'm capable of doing this operation

Full instructions were provided in the link to my blog on how to copy and save the code and how to install it into Bridge, it's easier than you might imagine. Give it a go!

[bersani_4639]

I added the script. In the caption field the text is not added but replaced. I don't understand why in ligtroom and other programs with metadata this doesn't happen. The text is added to the pre-existing one

[Stephen Marsh]

@bersani_4639 

I'm having problems understanding the separate image attachments, inserting inline images is usually easier to follow:

Can you simply type out the before/after description for the find/replace?

[bersani_4639]

after adding the script there were no changes. it is not possible to add
text to the caption metadata field.

[Stephen Marsh]

Again, please type a before and after example of the text (instead of the screenshot attachments). Then I can provide an example for you.

[Stephen Marsh · Accepted solution]

@bersani_4639 

Here is an example of 3 files, each with different, unique Description metadata.

When all 3 files are selected, the Metadata Panel indicates "(Multiple values)" in the Description field.

Now, in this example, I wish to add a common extra description to the 3 multiple selected files:

Before:

Red

Green

Blue

After:

Red_NEW TEXT

Green_NEW TEXT

Blue_NEW TEXT

In the screenshot above, I have used a regular expression to find the end of the current text, which is the $ (Dollar symbol, Shift + 4)

The common text replacement is _NEW TEXT

Here is a screenshot of the final result:

Where _NEW TEXT has been added to the end of all 3 selected files, retaining their original unique description and adding the new common description.

To add a common text entry at the start of the existing text, one would use the ^ (Caret symbol, Shift + 6) instead of the dollar sign.

Thank you so much. the method is very slow. impossible to do without knowing the program thoroughly. isn't there a keyboard shortcut to speed up the process?
with lightroom just position the cursor after the bracket of the text (multiple values) and double click to add the new text without changing the previous one. what i don't understand is why in a program like bridge which is expected to intervene on the metadata there are no faster paths to perform the changes. thanks again

[Stephen Marsh]

Thank you so much.

You're welcome!

the method is very slow. impossible to do without knowing the program thoroughly. isn't there a keyboard shortcut to speed up the process?

I wouldn't call it very slow, however, it's definitely not as simple or fast as you mention in Lightroom. Yes, it does require extra knowledge and a 3rd party script, such is life and the benefit of these forums to learn from other's knowledge and experience.

Bridge predates Lightroom and has a different development team.

This is not to say that Bridge shouldn't be able to do what Lightroom does, just that it currently can't.

image search using the "image description" metadata can make work efficient and fast, making the various tags, keywords, colors superfluous. I mainly use captions. unfortunately the few programs that manage workflows with metadata are very expensive and aimed at large archives. a useful program for managing metadata for personal or medium-sized archives was fotostation by foto ware. unfortunately now there will be no new versions. thanks
