Even the least compression means you actually lose some data, but I'm not sure we'd see it under normal circumstances. As you tell the camera to reduce the image size, you lose more and more. And that is before you start fooling around with it! Thanks for reminding me of that. keith -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
