I've made the upgrade to NC4.3 on my desktop, having waited through the NC4.2x series. Contrary to what I'd heard, it seems to run pretty snappily, but then, I'm running a dual-Xeon with lots of RAM. Multiple photos seem to run reasonably well, too. But... ... I'm not quite so sure about the D-Light function. It runs quickly enough (thanks be!), but it's obviously quite different than the old Digital DEE. There, I'd use settings like 16-1-64 (Shadow Ad.-Highlight Ad.-Threshold) or 16-1-90 to touch up a photo. However, I'm not quite seeing a direct tie between D-Light and Digital DEE. Any suggestions on how these correspond and on settings ? TIA. John P.
