  • Are you ever disappointed with your photos? Do you get frustrated when you’re editing because you’ve been told to move certain sliders, but never been told WHY? Do you wish you could transform your photos without having to spend hours in front of the computer? In my new book, Adobe Lightroom - Edit Like a Pro, you’ll learn:
    • how to to analyze a photo like a pro, saving you hours of frustration.
    • WHY you might want to move specific sliders, instead of just following recipes.
    • what the sliders are doing behind the scenes.
    • how to use sliders together, instead of in isolation, so you can get the optimal result
    The book is based on the cloud-native Lightroom desktop and mobile apps, but the principles also apply to Lightroom 6 and Lightroom Classic. The sliders are arranged into slightly different panels, but there's an included PDF that shows you where to find them in Lightroom Classic/6.

Corrupt Catalog

My lightroom CC program has been running very very slowly lately. I decided to check my 2012 mac mini system to see exactly what I have for hardware. I also have just run "optimize catalog" as a starting point and have discovered I have a corrupt. It has been a couple of years since I optimized my catalog so now I have many many additional images in my catalog so I don't want to lose all my efforts.

How can I restore my "current" corrupt catalog please?

What you can try is the following. Create a new catalog, then use ‘File - Import from Another Catalog’ and import your old catalog. Check the option to not move the images, but leave them where they are. When the import is finished, you should have a new catalog that is identical to the old one, except for any publishing services you may have.

If this worked fine, then this will be your new catalog from now on. Activate the option to make regular catalog backups, because that will verify the integrity and optimize the catalog in the process.
