Somehow I've lost 500 or so CR2 files. The previews were generated in LR5 and I can see them clearly - I generated 1:1 previews. I tried downloading and running this scriptExtractPreviews.lua.zip to extract jpgs from the previews, but it's not working. The script seems to run, but does not generate a jpg. Is there something else I can do to get jpg files? When I enlarge the preview files, I can see them clearly, so I am hoping there is a way to extract a jpg from it. Any suggestions?
google "Lightroom plugin preview recovery"
Thank you for responding so quickly. I downloaded the preview exporter (Version 4.14.1) and installed the plugin. After I selected the images I that I need, I got this message (see below) which is different from the instructions on your website. I just want to make sure that I run the correct script. Can you let me know what to do here? Thank you again for your help! I really appreciate it!
Preview recovery is in the plugin extras branch of the Library menu (not the file menu), or in plugin manager near the bottom.
If you have any other questions/problems with the plugin, please contact me directly, thanks.
