Hi Studio Photography,
If you chose to remove those images, then they should be there in some backup catalog if you did backup prior to removing them.
But, if you chose to delete those images from Lightroom, then I believe originals must have also been deleted from the hard drive.
Check in the trash if those images are present and can be restored from there.
Thank you for the reply... I moved them to the trash, and I don't see them on the hard drive or the trash folder. Thankfully I still have them on the SD card. I was just hoping to restore all the edits I did.
Thanks for the update.
You can copy the original images from your SD card to the hard drive or the location where they were stored originally and the edits can be restored only if you have a backup catalog that contains the edited version for those images.
Look for the backup catalog on your machine that contains those edits.
Thank you Chetna, unfortunately I lost the photos before I could make a back up... Thankfully I still had them on the SD card. So this will just be a lesson learned.
