I was looking at Image keyword tools, this Photoshop plug-in that helps photographers to add metadata keywords to their images efficiently and easily. Main tools: spell checker, correction suggestions, synonyms suggestions, sorting, deleting duplicate, and counting. Saving groups of words and complete Templates of Meta-data.
The plug-in has no limitations and is from 2006, I tried to visit the website for Deep Perspective but the link was not valid, but I thought it may be worth looking at the tool anyway.
First download the tool from CNET:Deep Perspective:
and save the zip file to a folder on your PC, the next step is to locate the folder and unzip the file to a new folder:
Open the the new folder and run the Install.exe file
When you run the Install it will ask you to drill down to the Photoshop folder on your drive and find the Plug-Ins folder
Finish the Install and Open up Photoshop, open any image you may want to save the details as a keyword template, or even a new image, then from the menu choose File > Automate > Keyword Editor
If the image already has the data you will see it in this dialog box.
There are a number of options to look at on the drop down like Groups, Spell Check, these you can experiment with, if you want to save the Images data as a template you just select the Save Template button.
Enter a Name for the new template and select OK
When you want to add this data to another image you just select the template from the menu, you can also create Groups and apply these to an image and save the metadata to the image file.
This is just an overview so you know where to find the Keyword editor, the way it could be used is to save Photographer, Copyright Notice as a template, and build and use the keyword groups for quick keyword insertion, and for sites that have a limited keyword set you could save these as well as a full set of keywords for an image type.
