You may have heard about Catalogs before as there are two main opinions among photographers. Some think Catalogs are the best way to work with images. Others remain skeptical and prefer to access and manage their image files directly without a catalog-based management tool. But what exactly are Catalogs? What are the strengths of database driven catalog systems and are there any downsides to this approach? In this article I will talk about Catalogs and explain the benefits and downsides of such post-processing and image management systems. I will also show you how to create and efficiently manage new Lightroom Catalogs.
1) What is a Catalog?
Adobe Photoshop Lightroom is a catalog-based post-processing and image management software. For someone new to such photo managing approach it may sound complicated at first. Simply put, a Catalog is a Lightroom-specific database file. Employing a database system means Lightroom does not work with the original files directly. Instead, it stores information about them – along with rendered previews – in a set of files that make up a Catalog. The list of such information includes metadata, filters, rating and adjustments you may have applied to a specific photograph inside Lightroom. The actual image file is not stored within the Catalog, only information about the adjustments and an image preview. Image files themselves remain wherever you decided to put them in the first place before importing into Lightroom. As a result, whenever Lightroom prompts you to back up your Catalog, it does not back up the actual images. Only the relative information stored in that Catalog is copied.
