Hi folks, Here is a white-wall shot taken with the DA* 50-135 @ 135mm F2.8, where it shows its highest light falloff at corners: www.dariobonazza.com/public/Vignetting.jpg
Do yo have any idea about how to measure that? I mean, how to translate Photoshop values (around 130 for each RGB channel at center, around 80 at corners) into f/stops? Thanks to anybody enlightening me ;-) Dario -- 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.
