[QUOTE="aroy, post: 537587, member: 16090"] I use NX-D for RAW processing and then exporting to 1000 pixels on the long side. Never faced this problem, even though I shoot in harsh tropical sun where the DR is quite high. Posterization during jpeg conversion depends on the algorithm used. A good algorithm will rarely posterize. Even if it does, there is no point in compressing to below 80% quality for posting on the NET. I should know, as I have written a lot of software in C++ and had to find a good JPG library (you will be surprised to know how bad some of them are, and they are used by a lot of commercial people). Good algorithms will take cognizance of the DR (at least for 8 bits) and not posterize. It is only when the algorithm is trying to aggressively do a global compress that problems start. [/QUOTE]
