Today’s Question: What are the pros and cons of Lightroom versus Lightroom Classic other than the cloud?
Tim’s Quick Answer: The core difference between Lightroom Classic and Lightroom relate to the fact that Lightroom Classic uses a catalog to manage photos while Lightroom provides a combination of local browsing and cloud storage. The catalog represents both advantages and disadvantages, depending on your perspective.
More Detail: The feature that is unique to Lightroom Classic is that it uses a catalog to manage the photos you import. The catalog enables you to quickly search across your entire library of photos incredibly quickly, and also enables you to work with photos (such as reviewing them and updating metadata) even if the source files aren’t available, such as when an external hard drive containing photos is not connected to the computer.
Of course, the catalog also introduces a risk into your workflow, in that if you rename or move folders or photos through the operating system rather than from within Lightroom Classic, you can end up with a large number of missing folders and photos and potentially have a significant mess on your hands.
Lightroom (the non-Classic version) had previously revolved exclusively around cloud-based storage, but now allows for local browsing as well. This takes away some of the advantages of the catalog, but it also enables you to avoid the risks of the catalog. You could, for example, only use the Local tab in Lightroom and skip cloud storage, or use cloud storage for limited purposes.
In addition, Lightroom Classic includes more sophisticated mapping features for photo locations, the ability to print photos, create slideshows and web galleries, and to create photo books that can be printed by Blurb.
When it comes to core features or organizing and optimizing photos, both Lightroom Classic and Lightroom are pretty much on par. When it comes to sharing photos Lightroom Classic provides an advantage. But the core issue is the catalog that is used in Lightroom Classic. I consider the catalog to be a considerable asset as noted above. You need to be careful not to make any changes outside Lightroom Classic, but as long as you follow this rule you can benefit from the catalog.
Perhaps most importantly, when making a decision between the two, I very strongly recommend that you only choose one of the two, and never mix-and-match using both of them in the context of your overall workflow. At the very least, using both version of the Lightroom desktop applications will likely lead to significant metadata mismatches for your photos between the two.
