Organizing Your Digital Media: 4. Working with Catalogs
Working with Catalogs
4. Working with Catalogs
This section discusses organizing with catalogs (databases) and metadata, using Adobe Lightroom for examples, including the following topics:
Digital asset management expert Peter Krogh writes that folders are ideal for storing things (The DAM Book, page 130), but are limited as organizational tools. According to Krogh, “metadata and cataloging software offer much more flexibility and efficiency for organizing than folders do.” (p. 131).
Adobe LIghtroom is a highly-regarded cataloging program used for images (and to some extent, video files). This guide focuses primarily on techniques using Lightroom’s Library module (not so much on image editing, which uses the Develop module).
Other software programs have different user interfaces but the concepts are the same.
How Lightroom files are organized
The following example shows one way to organize Lightroom files (as they appear in the Macintosh Finder).
Each Lightroom catalog includes both a catalog file (extension .lrcat) and a previews file (.lrdata), shown below in a folder called LR_demo_catalog. The actual image files are separate from the catalog files (in the above example, images are contained in a folder called demo_pix).
The images folder (demo_pix) and the Lightroom catalog are both in the same folder, called LR_demo. It is not required for them to be in the same folder. For example the catalog could be on your internal hard disk and the images could be on an external drive. But keeping them together helps to avoid confusion, especially when it comes to backing up your files.
IThe .lrcat file is the catalog itself, and the .lrdata file contains the previews of images (not the original images). The previews enable you to look at and manipulate images in your Lightroom catalog.
There is also a folder for catalog backups. (This folder contains backups of only the catalog, not the images.)
To avoid confusion you should know that while Lightroom is running, the folder containing the catalog files may look something like this:
Lightroom User Interface
The following is a brief overview of the Adobe Lightroom user interface.
The user interface is divided into modules (Library, Develop, Map, Book, Slideshow, Print, Web). The most relevant module for our purposes is the Library module, which is where you import and organize images.
The above shows Grid View, which displays a grid of image thumbnails. There is also a Loupe View, which show a single image at a time in the main content area:
Catalog settings and backups
Lightroom only allows you to open one catalog at a time. This is not normally a problem if you all your images in one catalog, which is recommended. To check catalog settings, choose Lightroom menu > Catalog Settings…
Lightroom automatically backs up your catalog according to the catalog setting for Backup in the Catalog Settings dialog box. Backup occur on exiting the program. If a backup is scheduled, the Back Up Catalog dialog box appears when you exit Lightroom:
Importing images into Lightroom
When you capture or import images and other media into your computer, consider how to import them in such a way as to make them easily accessible later. It is usually a good idea to keep your images (and/or video files) in their own space, separate from other files on your computer.
Often it is best to store images and video files on a separate hard drive devoted exclusively to that purpose, especially if you have a large number of images (and/or videos) that you are organizing using a Lightroom Catalog. Keeping images in their own space on a separate drive helps to avoid confusion and makes backing up files easier.
To import images into Lightroom, choose Import Photos and Video from the File menu, or click the import button.
The Import dialog box appears:
The import dialog box takes up the entire Lightroom interface throughout the import process. The components of the Import dialog box are described below.
In the left panel of the Import dialog box, choose the source (where you want to import from). Typically this will be a media card, but it could also be from a folder on a hard drive.
Copy, Move, or Add
An area at the top of the dialog box is where you to specify if you are copying, moving, or adding to your catalog.
- Copy as DNG copies RAW files and converts them to DNG format
- Copy copies files
- Move moves files
- Add adds files to the catalog without moving them from their current location.
Copy as DNG and Copy are usually the best options. What is the difference? DNG (digital negative) coverts proprietary RAW files to non-proprietary DNG format without losing any data. Many professional believe that this is a good thing to do. If you are importing files other than RAW (such as jpeg), there is probably no reason to convert the file to DNG.
Move is risky in the event there is a problem during the process.
Add prevents you from consolidating all your files to a central location (unless you want to import a file that already exists where you want to keep it). This can result in a Lightroom catalog referencing files from all over the place, which is not usually good practice.
Note: What is RAW?
RAW is a format for digital images that retains all the information captured by the camera. Unlike jpeg, RAW files are not compressed. They contain much more data that jpeg files which is a good thing for photo editing. Most professional photographers prefer to work with RAW files, and Lightroom is an ideal environment for that.
File Handling and Renaming
Lightroom allows you to select the quality of the previews it displays and to rename the files according to templates you can choose or create. For example, Custom Name + Original file number could result in filenames such as “SPHS_students-1236.DNG” (“SPHS_students” is the custom text you provide; 1236 is the number in the original filename).
Apply During Import
This allows you to assign metadata and keywords on import, which is not necessary but is very convenient. In this example I applied metadata from a template I created and the keywords “SPHS_students” and “HSL.”
Destination specifies where you want the imported files to be stored. Typically in Lightroom you would want all of you imported files to exist in a folder, which may include multiple subfolders, such as for year or year and month. In the example used for demonstration purposes in this guide the destination folder is called LR-demo.
Click Import and the files will be copied or moved to the destination, and the images will be added to your Lightroom catalog.
During the import process, and import bar appears that shows import progress. Importing may take some time, depending on the number and size of the images. If you choose to convert files to DNG format this will take some additional time.
After you import images, the Import dialog box goes away, and the imported images appear in the left panel of the Library panel user interface (along with any other images that you previously imported). Clicking on the folder in the left panel allows you to view and work with the files you have imported.
Moving Files and Folders
If you need to move or rearrange folders or files, you can do so from within the Lightroom. (And you should do it this way, because if you move the files outside of Lightroom, Lightroom will lose track of them, and you will need to re-import them.)
To move a file to another folder, you can drag its thumbnail:
You will get a warning message that allows you to back out:
If you want to verify where a file is, right-click on the file thumbnail and choose Show in Finder to find its location in your operating system:
Creating a New Folder
To create a new folder, click the plus (+) sign at the top-right of the Folders section of the left panel. Choose Add Folder…
To create a subfolder inside any existing folder, right-click a folder and choose Create Folder Inside…
Renaming Files and Folders
Ideally, it is best to rename files on import, as was described above. But there are often times when it is desirable to rename files that are already in the Lightroom catalog.
To rename images, select the image(s) you wish to rename, then choose the Library menu > Rename. This brings up a dialog box that allows you to rename the selected images.
When you click OK the images are renamed. The new names for the files will also appear in the Finder or Windows Explorer if you look at them there.
To rename a folder: Right-click on the folder in the left panel of the Library module.
Choose Rename Folder and then you can rename it.
Working with metadata
You can view metadata by looking at the Metadata section of the right panel:
Some metadata (e.g. exposure) cannot be changed, but some panel fields can be changed, such as Title, Caption, Rating, and Label.
It is optional, but good, to apply keywords and to images. This allows you to quickly search and find images later.
To apply keywords to images, select the images, then add keywords to the Keywords panel, either by typing them or clicking on keywords from the suggestions or keyword list.
Another way to apply keywords is by using the painter icon (in Grid view). Click the icon, choose Keywords from the popup menu, then click on thumbnails in the grid to “paint” keywords to additional images.
The easiest way too assign ratings (one to five stars) to images is to select thumbnail(s) and type the number on your keyboard. The rating is displayed in the filmstrip, metadata panel, and (depending on view options settings) in the grid thumbnails.
Another great way to organize images using Lightroom is through collections.
In Lightroom, collections are "virtual," meaning that a collection is a way of grouping images that can be located in different locations (folders). A single image could be in multiple collections, but only located in one folder. There is no need to create duplicate copies for different collections.
To create a collection, select thumbnails, then choose create Collection from the Collections section of the left panel.
Then give the collection a name, and click Create.
Using filters to find images
In Grid mode, you can use the Filter Bar to view images that match criteria.
To view the Filter Bar, choose View Menu > Show Filter Bar, or type the backslask key (\).
Click on a Filter heading in the bar (Text, Attribute, or Metadata).
Choosing Text allows you to enter text to search by several fields, including keywords, filenames, and metadata. In the following example, I search for filenames containing "sphs".
Attribute allows filtering by Flag, Rating, and Label. Just click on an attribute to filter. Below, I clicked on five stars to filter. Now, only thumbnails rated with five stars appear:
Filtering by Metadata has many options, including filtering by keyword, shown below:
