I just got a macro lens today and want to do some exposure testing with the istDS flash. I need a gray card but dont have one.
anybody know of a common household item that emulates 18% gray or an easy way to make one with the pc? I have an accurate incident/reflectance meter so I guess I could just do a bunch of gray shade printouts till i find the right shade but that sounds like too much work. jco -- 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.
