Backlit exposures

Neither of the cameras handle backlit scenes very well. (Technically, this isn't backlit but it poses a similar exposure problem). I think the iPhone relies on your using HDR mode for photos like this, rather than providing an option for metering off the subject. You can also tell the iPhone's autoexposure settings choices are a little strange.

(iPhone: 1/2900 sec, f2.4, ISO 64, pattern metering, AWB; 100 HS: 1/400 sec, f8, ISO 125, evaluative metering, AWB)
