My friend just acquired a Canon SD850 (digital camera). You can set the ISO setting to 1600, which I presume, somehow increases the sensitivity of the sensor. He is wondering why he can't get a good picture without a tripod or a flash inside this office at this ISO setting. I measured the EV with an incident light meter (Sekonic L-308) and at 1600 ISO, I get an EV reading of 11.4. Just wondering if anyone has any comments on why he cannot seem to get a good photo in these (not so low) light conditions.
