the trial version is just limited to how many photos you can take, allowing for you to test out all the feature unrestricted. Once the limit is reached the trial comes to an end. I always recommend the HDR 2xp with the High options, really shows the capabilities of fhotolens, just one thing in landscape layout there is a bug with the tap to focus. The fix is already on it's way and awaiting approval. So for a landscape shot just don't tap to focus and auto focus will kick instead which does work. Portrait layout has no tap to focus issues.
