What is the best software to manage photos? I know this is a question which has been asked in the past, but I want to add two constraints:
- Open format. If in 50 years someone wants to look at the photos I have taken, I want them to be able to extract the metadata from my photo no matter if the software I used to tag the photos exists or not.
- Free. I cannot imagine paying a monthly fee to Adobe for the rest of my life. The day I stop paying, I lose the metadata.
- Works on Windows.
I really like using Lightroom 5, but I am worried that Adobe will tell us in a few years that we cannot use it anymore (https://www.vice.com/en_us/article/a3xk3p/adobe-tells-users-they-can-get-sued-for-using-old-versions-of-photoshop).
Over the years I have taken 30,000+ pictures and I would really like to be able to tag them all with confidence that the tags won't be lost because of a software license.
