The thing is though, I wouldn't call a simple sunlit
landscape a "lighting problem". After portraits, sunlit
landscapes would probably be the next most commonly shot
thing - by pros, keen photographers, and mum & dad snapshooters.
I've taken countless landscapes myself, on equipment ranging
from 35mm rangefinders with no light meter, through to
mid-range DSLRs. Yet, I never had a single problem metering
this type of shot, until I got a DSLR. Getting these shots
nailed ain't rocket science. If you have no meter, sunny 16
and open up a bit if it's hazy/cloudy. On my old cameras
that had meters, I could always trust it - even using slide
film. Your gut feel would tell you if a shot warranted
adjustement of the exposure (snowfields, beach etc), but a
simple sunlit landscape wasn't one of those situations.
Manual mode and sunny 16 tends to go ok with my digitals,
but you should still be able to trust the meter, and IME,
you can't. Trust the meter and you'll get a white sky pretty
much every time. This is what I've found with my Canon and
Samsung/Pentax gear, and from what I've seen from others
with the 2-digit Nikon bodies, they handle it even worse
than Canon & Samsung/Pentax.
When I was selling cameras, it would be a fairly regular
occurrence that people would bring Nikon DSLRs in claiming
they were faulty because of this very fault. I'm not talking
about the mum & dad snapshooter with their first DSLR camera
- they probably don't know enough to recognise that they are
getting overexposure. I'm talking about people who are
seasoned photographers, professionals etc.
Yes there are workarounds, and someone with a bit of
experience knows that if they go manual, put negative EC on,
bracket, or use the histogram they can get a correct
exposure. But the fact remains that auto exposure,
especially in a matrix mode that supposedly analyses the
photograph and adjusts for the type of photo, should not get
something as common as a sunlit landscape fundamentally wrong.
