Images with K7 coming out entirely GREEN - WTH?
I wanted to take some pictures of a new wall unit I'd finished installing in the dining room. I decided to light it up with the internal (halogen) lights and do a long exposure on a tripod so everything would come out crisp. Set up the K7 on a tripod, into Av mode with the aperture cranked down to f/11... took a shot and the preview was entirely GREEN (this image is from the processed RAW file - which was obviously no less green). http://charles.robinsontwins.org/photos/2010/IMGP6544.jpg This is just a 4-8 second exposure under tungsten lighting. Shouldn't be green. I took about 7 or 8 images which all came out the same way. Turning the camera off and on between exposures... scratching my head Finally I popped up the BIF, took a quick shot which looked normal. Back onto the tripod, it worked perfectly: http://charles.robinsontwins.org/photos/2010/IMGP6548.jpg So.. what the HECK was going on there? This was a freshly-formatted card with a fully-charged battery. Confusing to say the least. -Charles -- Charles Robinson - charl...@visi.com Minneapolis, MN http://charles.robinsontwins.org http://www.facebook.com/charles.robinson -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: Images with K7 coming out entirely GREEN - WTH?
Did you check your white balance setting? Popping up the flash changes the WB to the flash setting, so it would look fine. Turning off the flash reverts the WB to where it was previously set. So, If for some reason, your WB was off, or Auto WB was giving you strange results, that would be consistent with what you describe. gs George Sinos gsi...@gmail.com www.georgesphotos.net On Fri, Nov 5, 2010 at 8:56 AM, Charles Robinson charl...@visi.com wrote: I wanted to take some pictures of a new wall unit I'd finished installing in the dining room.

Popping up the flash changes the WB to the flash setting, so it would look fine. Actually, the custom menu setting I have says that the white-balance while using flash should be left at Auto - which shouldn't have changed anything. (which is the default setting) Setting it manually (thinking it would affect the preview image, even if not the RAW file) to Tungsten balance made no difference. The shot I posted might even have been with the tungsten setting. -Charles -- Charles Robinson - charl...@visi.com Minneapolis, MN http://charles.robinsontwins.org http://www.facebook.com/charles.robinson -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

I don't know what the color temperature and spectral balance of those halogens coupled with the translucent material of the wall unit might be, but they're sure fooling the camera's AWB setting. Of course, if you're capturing raw format, white balance means almost nothing.

I was actually more than half serious because you can clearly see only the green channel was recorded so it must have been either sensitivity or readout. hope it doesn't come back. but it does fit in nicely with the Vampire Camera theme ]=) -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
