I am one of the millions that subscribe to the CC plan at the approximate monthly cost of beer in a six pack. I believe it to be the most fun, adaptable and useful photographic system ever.

From Victoria Brampton, the "Lightroom Queen":

"Believe it or not, Adobe has been listening. A change was quietly made to the Lightroom 5.5 release to allay your fears.

As long as you’re running Lightroom 5.5 or later, if your subscription or trial version expires, you can continue to use Lightroom excluding the Develop module, Map module and mobile sync.

Yes, you read that correctly! You can import new photos, add metadata, organize them, search for specific photos, do rough edits using Quick Develop, apply Develop presets, create books, slideshows and web galleries, email and publish photos on social media, export and print your edited photos… nothing is lost!

And when you’re ready, you can renew your subscription or buy a perpetual license to unlock the main Develop module, Map module and mobile sync (sync is subscription only, of course) and use Lightroom to the full.

That said, if you want to ditch Lightroom, Adobe makes it easy. First, even on the CC plan, when you quit the Develop module will stop. But the Library module will continue for you to preserve, view and use your work."

Furthermore, Lightroom makes it easy to save all your work for any other editing system. Create a selection limited to all the images you've worked on. Then do a mass export to your favorite file format for use in any other software.

The steps:

Library menu: Select "New Smart Collection"
Choose a name like "All Edited Images"
In the Match selection box choose "All"
Below that box, select Develop >"Has Adjustments" and "is true".
Export the entire collection to appropriate drives or folders.

Last, abandon Adobe and move on to whatever you like.

Be Happy! You're not a slave or hostage to Adobe!
