impossible. you cant change image DOF after the fact. you may be able to do some minor fiddling but if the fstop was near wide open and not tilted to match a tilted subject, there is no way to get the suject totally in focus without a tilt used at time of exposure.

If you need to emulate a true scheimpflug effect, you would probably find it easier to do with Helicon Focus, although Tony Kuyper has an ebook tutorial out that includes digital scheimpflug. http://goodlight.us/writing/digitalscheimpflug/digitalscheimpflug-0.html -- 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.
