Thanks Bruce something that I forgot to add in my message is that I am seeing it in the RAW file and that it is a bit better in the JPEG file. I am going to play around with the settings and see if perhaps I should tone down those settings when there is a chance of having the blue sky in the shot. I will also keep your tips in mind when I am editing the photos.

Can't say if that could be a problem myself. Where other people view your image is rather out of your control. You could put a perfect image online but someone viewing it on a crappy laptop's TN screen could see banding and figure it's your fault. Either ignore that possibility or use the random luminance noise trick to mask it. -bmw -- 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. -- 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.
