Just nine seconds separate these two pics. They are almost identical
shots. Both were made with the istDs, both at a rating of 3200 ISO, both @
70mm, both at an aperture of 5.6, both using multi-segment metering, both
using auto focus (more on that later!), both on one of the automatic modes,
yet they are a stop apart, with the top pic made @ 1/30 sec and the bottom
@ 1/15.
What crummy results these are. The pics, imo, should have an identical
exposure. They would were a funky old manual camera body being used. Is
this the kind of erratic results one can expect from high-tech cameras, or
is there some sort of failure to communicate or understand on my part? Why
would these pics be so far apart in their results?
Wrong metering mode?
The picture appears backlit. The man in the background right and the
additional highlights just left of the door jamb could be enough to cause
the camera to adjust a stop. Multi segment metering would be much more
inclined to this then center weighted or spot. I'm not a great fan of multi
segment metering for most situations, preferring old center weighting for
most every day shots and spot when needed.
I'm catching up on the digest so if this has already been suggested, sorry.
