I converted my raw files to dng with preview set to medium instead of set to full.
On the other hand in Lightroom, there are several preview option (minimum, 1:1, etc.); I always use minimum because Lightroom build a larger preview size on the fly when needed and keeps in the cache for 30 days.
I am wondering if I really do not need to convert raw files with the full preview because Lightroom will build a larger preview within Lightroom. This would save 10-15% smaller DNG file size.
I saw photographers converting to compressed DNG with super small file size and it seems not to make any real difference in Develop's visible large preview.
Thoughts? I appreciate your feedback. Thank you.
