I'm using the latest LL classic on a MacBook Pro. My main camera is a 40megapixel Sony. When I'm home, I store all my files on a NAS. When I travel I have a local working directory on my SSD that I import/edit files in until I get home, then I move to my NAS (both on same catalogue). I have a question about previews. When I use Lightroom to edit or view, I like to have 1:1 previews so that I can zoom. My previews take about 300GB for ~200k of photos which I'm ok with. I had also created smart previews while importing. I just went on a business trip, and it seems that something wasn't working as expected; When I tried to view the images didn't seem 1:1 previews, and when I tried to export small (1200x1200) files that exist on my NAS (that I'm not connected to) for social media, I was unable to do that either, so I deleted all previews, and am now recreating them in case there was any corruption. Can someone please confirm my understanding: - 1:1 previews allow zooming and load faster than accessing RAW files - Smart previews can be used offline for Lightroom editing and exports up to 2k Based on above, I believe I need both for what I'm trying to do- is that correct? Any ideas on what went wrong?
