Hi, Sorry for the double posting. I posted this on the Technical Forum, but afterwards thought it might get some more views here. "I have just signed up for Smugmug and uploaded two photos. The originals are of similar nef quality. The first photo ended up as 400kb after resizing and looks o.k. with minor artifacts. The second one has ended up with unpleasant artifacts, even after increasing the jpeg quality and increasing the size to something like 1.6meg. Does anyone know the ideal workflow to arrive at a quality image on Smugmug when starting out with a Nef? Thanks in advance for any help you might be able to offer. " Regards, Steve D.
