It looks like I am getting a very reasonable exposure with my DS in a daylight setting. In lower (not incandescent) light it tends to be underexposed by ~0.3-0.7 EV, as you said. I wonder if this was somehow "by design". I remember that they did it in Nikon D100, so that the photos were underexposed by 0.5 or 1 EV, to avoid burning the highlights.
I tend to agree with you on the hypothesis how the WB is related to metering with incandescent light.

In bright circumstances, and low ISO settings, I nearly always needed to add .3EV ... at ISO 400-800 and low light, tungsten illumination, I needed to set .7EV. The K10D does much better in this regard, I'm much more of the time at 0 to +.3EV. White balance should be of no consequence, although it's possible that changing the white balance somehow affects the metering calibration ... dunno. Although it is true that imaging and metering sensors are more sensitive to light in the red/IR range than in the green/blue range, and incandescent light is shifted way into the red range, so maybe the adjustment to WB could affect it in that way somehow... -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
