New XTI cameras: underexposure problems?

Because the house, not the foliage, appears to be the subject, I prefer the first image. In the first image, there is more detail in the house and I find its tones (as well as those of sky and sidewalk) richer and more pleasing to the eye.

The blocking up of shadows in the foliage doesn't disturb me, because the size and location of the foliage relative to the image make it clear to me that the foliage is more or less incidental to the subject matter.
 
For me, the brighter picture is overexposed on the house and sky; the
darker one is underexposed in the shadow detail. Is this a question
of the limited dynamic range of the camera?
This comment is interesting to me. Maybe I'm wrong about this, but I don't think I've ever used a DSLR that couldn't deliver greater dynamic range than Velvia, or even Provia. It seems to me that with the advent of digital manipulation -- or, more specifically, the shadow/highlight tool in Photoshop and then HDR -- came a bias toward the middle, a sense that every detail of every shadow or highlight must be displayed.

And with the advent of cameras that display histograms, there seems to have come a quest for "the perfect histogram," a gently sloping bell curve with a peak in the middle (or wherever one "favors") and ends that taper off just short of each edge of the rectangle. Never mind looking at the scene in question, deciding what the subject is, and determining how best to emphasize the subject and convey the message... instead, point and shoot, review the histogram, and adjust exposure to push the curve around the rectangle so that "every detail" is captured.

If we place our emphasis on milking every last detail out of a scene, are we losing some of our ability to communicate what is important about the scene?

True that if maximum detail is captured, then one can always decide in post what to emphasize and what to minimize, but shouldn't we have some idea of what we're emphasizing and minimizing when we compose an image in the first place?

It reminds me a bit of when people (self included at one time, with occasional and sometime purposeful relapses) discover the saturation tool and go wild, producing impossibly deep green foliage, poster-blue skies, and vistas of red and yellow that scream, "Look at me, I'm a phony image you'll never see in real life!"

Or when people read that all digital images need sharpening and, determined that every image they process must be sharp enough to make your eyes bleed, whip out the USM tool and oversharpen a picture to the point that hair, eyelashes, or other fine details are a pixellated mess.

Will FDR (fake dynamic resolution) become the next cliche of digital photography?
 
Yes. Exactly. You're correct.
Because the house, not the foliage, appears to be the subject, I
prefer the first image. In the first image, there is more detail in
the house and I find its tones (as well as those of sky and sidewalk)
richer and more pleasing to the eye.

the size and location of the foliage relative to the image make it
clear to me that the foliage is more or less incidental to the
subject matter.
 
That, and I suspect their 'fix' is to up the exposure compensation of
those costumers that don't like the current exposure readings. So the
cameras that are 'fixed' have their internal software adjusted so
they are at a +2/3 exposure compensation when centered at 0.
And you would be wrong.

Fixing the chronic underexposure common to many XTi cameras available from launch until about February/March 2007 could not be accomplished merely by boosting EC or FEC. Why? Because the gravity of the underexposure was inconsistent.

Canon fixed my camera by replacing hardware. It is now spot-on. They did not open it up and rip out its guts for nothing.

Further, I've since upgraded the firmware in the camera to 1.0.5 which had NO effect on exposure -- proving for certain it's not some software adjustment.

I can only speculate as to what is the cause of the problems -- I am guessing that Canon had two or more suppliers for a single components and at least one of those suppliers provided a part that was not quite compatible or up to spec. This would explain why some cameras were OK and many were not, and also how faulty cameras ever got past Canon QA.

Between myself and my acquaintances, out of 4 XTi cameras purchased before march 2007, all 4 suffered from chronic underexposure. Of the 2 XTi cameras I know of purchased by friends in April and May, both are fine.
