Originally posted by aleonx3 I believe if you set the AW to FLASH, the information is recorded in the EXIF and will only be applied to either in-camera JPEG or when you process the RAW file (with default WB set to FLASH).
This is what I expected the camera to do. The problem is that it's not what it does. No matter how the camera is set, with or without flash, WB is always saved as "Auto" in the Exif for the DNG. Or, in other words, the K-500 doesn't do what you think it should do by not correctly saving the selected WB in the exif.
So, when you look at the previews, you think they all have the same WB (because you fixed on the camera) and start wondering what's the problem with your setup because it shouldn't be so cold, warm, or just changing from cold to warm between succesive shots... This was what I thought when I write the original message: something was wrong with my flash or setup. I didn't thought that it was my camera saved the wrong WB data in the exif.
Thus, I'm wondering if this behavior is common to all Pentax DSLR or only with the K-500. Do they all saved WB data as "Auto" in the exif, or do they saved what was set on the body like they should do ?
EDIT
Okay, I was looking at the wrong line in the exif. The problem is only present when a flash is used. Without flash, the WB data is correctly saved in the Exif. With flash, the WB is always saved as "auto", no matter what is set on the body. The problem is present regardless how the flash is used (onboard, external on hotshoe, wireless).

I've found the problem!
In the C2 menu, item 9 "WB with flash", the default is that the camera forced back in Auto mode when flash is used. Setting it to 2 tells it to use WB as set by the user. This solved the problem.
Thanks again guys for your help!
