I bought Lightroom 5 a couple of months ago and have been using it without any issues, then out of the blue I ran into export problems. Sometimes the exported images wouldnt have the sharpness adjustments, sometimes it wouldnt have the noise adjustments, sometimes the saturation or vibrancy, and then sometimes a combination of the above. I know theres a known issue that effects noise on export if you export on files sizes less than 1/3 of the original size, but mine have always been exported at full size with image quality 70, exporting as jpeg. I installed the latest update and that didnt help. I uninstalled the software and that didnt help either. I then uninstalled everything completely (including the library) by searching both lightroom and adobe in finder > system files> are included and deleted everything I could find pertaining to adobe lightroom (I didnt delete everything adobe as I have other adobe products). This didnt help either, although Im pretty sure it didnt delete completely from my system as when I reinstalled LR it still had all my preferences such as my watermark. So has anyone any ideas on what my issues are and how to fix them, and also how to completely remove LR and all its other files from my system, without deleting everything else adobe? Ive tried the advice on here too http://helpx.adobe.com/lightroom/kb/manually-remove-lightroom.html but even though it starts as a new bit of software (ie shows you all the tips etc again) there's still some memory somewhere as it doesn't ask for my license key, and when I import an image that I've used in LR before it already has all the changes to it (ie sharpening etc) despite it starting a new library. Whether this is because its somehow reading from Photoshop CC and/or Photoshop essentials or not Ive no idea? I have tried using Aperture instead but find that the noise reduction in aperture isnt a patch on LR, even when using the RAW fine tuning. Also, I think this is the first apple software I have use that I think another similar software has a better interface.
