I have seen PTLens recommended for perspective correction. It is half the price of DxO ViewPoint, so I downloaded the trial version. It will not work as a Plug-In for Affinity , but the standalone runs OK. However, I cannot see any way to save the corrected image. It shows the corrected image in a preview but there is no option to save this. It does say that you can only use the trial version on 10 images, but there is no suggestion that you cannot save them.
I have googled for an answer, and looked in the Help file, and searched the author's website, but there is no information available.
Has anyone any experience of this? The only 'helpful' suggestion I have seen is to buy the full version. At $25 this is not expensive, but I am reluctant to buy from a source which cannot get the trial right.
