One advantage of Lightroom is that it really good for cataloging your photographs. I think the aforementioned free programs can do this as well but they may not be as efficient. I use digikam to organize my photos, process then in rawtherapee, and then send them to affinity photo for any final edits. Affinity photo is a Photoshop competitor that is a one time fee of ~$50 on sale.
