It's remarkably cumbersome in terms of GUI, but when it comes to raw conversion power (pun intended), it's unbeatable. To use what may be the most mediocre converter as a comparison, I compared my 14 bit D300 RAW file as opened by Leopard in Preview to one opened in NX2. The difference is amazing. Leopard must be throwing away a lot of data, RAW file or not. The NX2 version looked tremendous. The colors pop in a way I've never seen with any other program. Any similar experiences out there with fellow Nikon users?
