There's also the question of the display. The evening I shot these photos: http://www.flickr.com/photos/ellarsee/sets/72157626084484859/ When I previewed the shots, all the pictures of my very purple hat looked blue. On my display, the purple in Igor's pictures looks pretty purple, and the forks and plates look pretty close. Is it possible that Igor's display just doesn't have the dynamic range to properly display the purple without tweaking the other colors? > > > -- > PDML Pentax-Discuss Mail List > PDML@pdml.net > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
