Filing System for Digital Photos

[Oogiem]

Are there any suggestions on what application works well to file and backup photos? What filing system is working well for you folks to manage your digital photos?

I use Adobe Lightroom, and ham working on thousands of my own digital photos. separate catalogs for hundreds of scanned historical photos and also scanning a backlog of my own running into the thousands of old slides, negatives and prints.

Powerful, hard to learn on occasion but very good once you get it.

Buy Victoria Bampton's book, very useful!
