[QUOTE="WayneF, post: 544818, member: 12496"] The Exif have different settings, but I have no explanation for the flash failure in one. The white one says Portrait scene mode, Picture control Portrait, Saturation Normal, and -0.9 EV exposure difference. The "normal" one says Standard scene, Picture control Standard, Saturation Auto, and 0.0 EV exposure difference. So the scene mode setting changed between the pictures, but the flash difference surprises me. Both say Flash Compensation - 393472. That seems a bad garbage number, it should say 0.0 EV, or 1.0 EV or something, but it should not be a nonsense number like this. That is probably just a problem in the Exif Viewer incompatibility... Which Exif Viewer was it? The flash mode was auto TTL BL. Both exposures are 1/60 second f/3.5 ISO 800. Yet the white one thought that was nearly a stop insufficient ambient exposure, and really hit the flash exposure hard. Seemingly a lot more than one stop more. We don't actually know if it was due to the setting change, but either way, it would seem to be a defect to me. You would want to learn more by seeing how the specifics repeat, can it be duplicated? I would not expect scene mode change to cause this. I don't have any experience with flash in Auto mode, that seems the hard way (no user control at all). I know you want it to work in Auto mode, but I'd try camera A mode to see what happens. In camera A mode, you have to check that menu E1 says flash is in TTL mode. And in camera A mode, you must open the flash door if you want to use flash. It probably does not default to Auto ISO either (often a good thing with flash, certainly for this picture). What Auto mode will do in indoor situations is to raise ISO and slow the shutter and open the aperture trying to make the ambient exposure sufficient, without flash, if possible. I don't know if ISO 800 is a limit, but 1/60 and f/3.5 probably are at limits, of the lens and for the flash. Then the flash would be at minimum fill level (instead of the main light). This can leave the incandescent ambient orange, and the flash is white. Note in the "normal" picture, there is a flash shadow under the desk lamp, the flash fired, but even the laptop screen is correctly exposed by the ambient exposure. It has a lot of ambient exposure, even though flash is used. [/QUOTE]
