I'm not entirely sure I understand what you're suggesting here. Do you mean a selective area way to cook an image to grayscale, emphasizing different color-tonal relationships depending on location in the image? You can do this easily in Photoshop using multiple channel-mixer adjustment layers and masks. Lightroom isn't a layered editing environment and this sort of tonal transformation is not implemented as options in a brush action so it's not the right tool for that at present. -- Godfrey godfreydigiorgi.posterous.com -- 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.
