Collections allow you to create virtual groups of photos across your catalogs without any need to move the files themselves. You can also create sub-collections within a larger collection. Each collection tells you how many photos are in it, and you can pull them up just like other contact sheets.

Create a collection by right-clicking in the collections section.

Photo Mechanic Plus is currently in a limited public beta. 

You can discuss any questions, support issues, or other feedback in the Photo Mechanic Plus Beta forum. Camera Bits staff can respond to your questions and feedback there.  As with any beta release, we strongly recommend caution when installing and using Photo Mechanic Plus Beta with any important projects or when you are on a tight deadline.
