I have created a video explaining the pros and cons of using single versus multiple catalogs that you can watch here. With that in mind, I know that there will be some photographers who’s workflow require using multiple catalogs. However, there are a few items that need to be set up every time you select File > New Catalog (such as Identity Plates and Collections). To avoid this repetitive step, I would suggest that you create a “template” catalog. In the template you could set up your Identity plate and Collections. Then simply duplicate the catalog for your new client and go right to work.
Note: To create a new catalog select File > New Catalog, choose where to save it and give it a name. Set up your identity plate (for a video about Creating Your Own Identity plate click here). You will need to import one photo into the catalog (any photo) to set up your Collection Sets and Collections.
