We can't know. You have left out the most important part: What product are you actually talking about?
I thought I was in the Adobe Create Cloud for Lightroom 6 CC
I did not realize that it is a generic discussion.
Aperture and Capture One Pro 8 are alternatives to Lightroom.
Again, my apologies as I just signed up for this forum
The trial is fully functional, and has no limitations whatsoever.
If you decide to subscribe after 30 days, you just keep on working - the catalog will be same as during the trial.
Lightroom 6 and Lightroom CC are basically the same program, but licensed differently. Lightroom CC is what you install if you subscribe to the creative cloud. There is a photography package that is $9.99/month in the US. If you download the trial version, this is what you will install. There are no limitations on the trial version. Everything works. If you subsequently decide that you want to purchase Lightroom 6 as a standalone version then you will no longer have Lightroom Mobile, you will not have the Dehaze filter, and you will receive no feature updates. Lightroom 6 will, however, receive updates to accommodate new cameras. If you decide to purchase the standalone version then the only way you will get new features is when/if Lightroom 7 is eventually released. It will be a paid upgrade to Lightroom 6.
