I often take photographs in my girls' room, which has big green fabric leaves from Ikea near the ceiling. Bounce flash works great in there, but everything, not surprisingly, ends up with a green tint. Now, I can -- and do -- set the white balance perfectly with a gray card. But since the lighting there is always the same, what I'd _like_ to do is transfer that setting to one of the three custom white balance settings available.
Unfortunately, there's no way in-camera to read what the snapped white balance is (is there)? There's some possible information in the extended EXIF info, but I'm not sure exactly how to interpret it. On the other side, the G-M axis and B-A axis settings in-camera are without units -- who knows what 1 step of GM compensation means? I mean, literally, "who knows"? :) Since the LCD isn't color calibrated (and unlike the K20D isn't even adjustable), it's hard to tell exactly what changes there are going to do. I never seem to be able to really get 'em right dialing them in. My Olympus P&S camera had a feature where one could store three (or was it four? -- I forget) different shutter-set custom WB settings. That was infinitely more useful to me than the custom K settings -- even if I had expensive lighting with documented output, a gray card reading would probably be more accurate anyway. (And yeah, I know that shooting in RAW would relocate the problem to my computer where I could address the issue in various ways. But I should be able to do this in camera, shouldn't I? Thanks in advance.) -- Matthew Miller [email protected] <http://mattdm.org/> The Definitive Pentax P-TTL Flash Model Guide: <http://pttl.mattdm.org/> -- 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.
