ho notato del problemi nel modulo sviluppo. in pratica quando applico le impostazioni automatiche alle foto, in alcune, mi spegne a -100 le Luci e la foto risulta nera
The Auto Settings algorithm is very good but not perfect. Your screenshots show really bad results, though, and I haven't seen similarly bad results posted here before. To troubleshoot whether this is a result of the imperfect algorithm or a problem with your LR installation, please upload the original NEF to Dropbox, Google Drive, or similar, and post the sharing link here.
p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
