You'r very lucky to have never seen it. Google has heard of it. You'll find plenty of references there. Frank Theriault pointed it out in one of his pictures a year or two back. Here's a photograph with some serious shadow banding: https://picasaweb.google.com/lh/photo/UZHmptXW4qsffklRS3lX_aAuqTB9pnndhHCi9-Fvgfs?feat=directlink Here's my repair: https://picasaweb.google.com/lh/photo/a75LaelivUllMwgs9RCR56AuqTB9pnndhHCi9-Fvgfs?feat=directlink That's about as bad as it gets. The histogram doesn''t show any shadow clipping, although most of the tonal distribution is towards the left. Even so, there isn't much room at the right to raise the exposure. Another stop more would have seen clipped highlights. The grain/noise isn't as bad as this suggests, but the resizing seems to have worsened it. You can get a picture to display bigger in Picasa by closing the information panel on the right. Click on the >> near the top right corner of the picture. regards, Anthony "Of what use is lens and light to those who lack in mind and sight" (Anon) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
