  • The November 2019 Lightroom updates are now available. Lightroom Classic includes the ability to export the same photos as multiple sizes/formats in a single export, content aware fill for panorama edges and more. It does require a catalog format upgrade and there are updated system requirements, so you may want to wait a few days before upgrading.
    Lightroom (cloud-based service) has export options (such as TIFF format, renaming and color space), custom sort order on the desktop, copy/paste to multiple photos on iOS and more.
    The Missing FAQ and Edit Like a Pro eBooks are already updated for the changes.
  • Stop struggling with Lightroom! There's no need to spend hours hunting for the answers to your Lightroom 6 questions. All the information you need is in Adobe Lightroom 6 - The Missing FAQ!

    To help you get started, there's a series of easy tutorials to guide you through a simple workflow.

When you upgrade to subscription, there's also a Lightroom Classic version available.

I am helping a friend who uses Lightroom 6 (I use CC). He has just got a new computer and has all his photo files as before but of course when he opens Lighroom there is nothing in the catalogue. We tried opening from the last backup catalogue which is stored on his external drive but get the message Lightroom cannot use the catalog named 'Lightroom Catalog' because it is not writeable and cannot be opened.

Any help would be gratefully received.

Then the drive it is on is not writeable for Lightroom. I get the feeling you have two threads going on about the same subject, so maybe we should close this one and only continue with the other one. Cannot open from backup
