Yes, Lightroom is available as a one time payment as @buddingphotographer said. Lightroom 6 will be quite a step ahead too. If you have time to edit photos, I would definitely recommend it! The results you can obtain so easily, are astounding. As time goes by, I keep learning how to do more and more, so it seems like the software never ends! You just keep finding new stuff. (I don’t have time to watch the tutorials….) You can also nearly entirely recover images that were “beyond redemption” if they were important -and shot in RAW. So glad you got the photos resolved!
