They are smaller because they are only the preview images that Lightroom uses to display.
I get that, but why would only the ones that I did anything to with be smaller... the rest I can understand..
* The larger previews no longer exist.
* there is a problem with the ExtractPreviews.lua script - it's not finding the larger previews.
Consider trying PreviewExporter's recovery feature to compare - let us know if there is any discrepancy.
Hi. I've been trying to extract previews (after losing ALL my original files when I dropped and damaged my hard drive) but can only fin the process for LR4 onwards. Where did you find the LR3 instructions for this?
As you say- The Extractor by Jeffrey Friedl only works with Lr4 and above.
This site might be worth trying as a last resort-
