pierre rochon Posted July 8, 2014 Share Posted July 8, 2014 I'm working on an image taken yesterday. It's a picture of a circus big top with yellow and blue stripes. Raw file, 16 bits. Depending of the angle of the stripes (spiral pattern), the junction between blue and yellow is pixellized in a staircase pattern at some places, on all of the four frames I took. Those artefacts appear in no other image, in fact I've taken many thousands of pictures with my D700 and 24-70 zoom, and it is the first time I see this. I was using a polarizing filter. The pixels are visible in the raw file without sharpening. Anybody knows why this happens and how to get rid of the artefacts if possible?

DDoug Posted July 8, 2014 Share Posted July 8, 2014 Based on this 2009 thread in DPReview, you might try downloading trials of alternative raw converters: http://www.dpreview.com/forums/thread/2620991#forum-post-32378971 One of the respondents says, "Edges that were jagged in PhaseOne Capture 1 were fine & smooth in Capture NX2."
