For the purpose of getting some 'grab shots' while driving taxi, I
finally settled on a point-and-shoot Pentax Optio A30. The shake
reduction was the primary consideration. OFten the pictures I want to
take are night scenes with lots of radiant lights, which quickly show up
blur from pressing the shutter. Here are a few test shots, in the wild,
after having read just enough of the manual to know how to load the
battery, and using all automatic settings. I was quite encouraged by
the results.

Looking forward to seeing these pics - looks like you've exceeded your
daily bandwidth from the hosting provider, though - popular shots, no
doubt. :-)

Well it does seem to keep it stable, I have to use the burst for such
things and hope at least one comes out okay. Is it me though or do they
seem a bit noisy close-up? Only a problem if you decide to do some close
cropping, but have you got any stable shots with the IS system turned off?
Good photos though, you need to create a dashboard swivel mount :-)

I like the urban feeling in the photos.
Maybe you could do an entire urban photo series, using the same kind
of urban ambience as in the second photo.

Yes there are far too many variables for this to be a useful test. It
was more a matter of basic proof of concept, can I snap a shot from a
moving car or in low light and get something even remotely useful?
Previously, this was not possible. And yes, next I will try some shots
'in the field' with side by side comparisons of SR turned on and off.
Understaning the noise and jpeg artifacting will require me to boost my
understanding of how digital imaging and how these digital cameras work
by a factor of 1000 at least! But it seems to me that focus, exposure,
and what is probably some sort of automatic digital filtering applied by
the camera's various exposure 'modes' are all factors in this. Further,
these shots were cropped, resized, and saved from Photoshop at different
jpeg 'quality levels' in order to get a file < 1 Mb each time. In
general the texture in the the foreground pavement seemed to be the most
sensitive to artifacting and is what I kept my eye on when resaving the
images.
Since I used fully automatic settings, how the camera acquires a focus
automatically a factor I think.

Still getting the message:
The daily bandwidth limit for this customer has been exceeded. Try again
after midnight, EST.
Click here for more information.
When going to that URL. "Here" is a link, and it says nothing
particularly useful (just links to the site's main page)

Thanks Warp. Yes, I find a fascination in the second photo with the
density of information and simultaneity of events. That sense, perhaps
the 'ambience' of urban life to which you refer, is what I find so
captivating about the city and is something that I can remember excited
me from the very first time I got off the bus exactly 30 years ago. I
can remember how, in those days, I used to write letters to friends
describing my experiences here, and would dwell on the activity, on a
single street corner, in a single moment.
Interesting to me about that second photo is the car's rearview mirror.
It is both tiresome and unavoidably cliche, but also very difficult to
avoid including when framing shots from inside the window of the car. I
wonder if it could add a 'dimension' to be exploited with this kind of
image.
A further dimension that is not communicated in the shot is how I am
taking it while simultaneously turning to deal with the instructions
from a customer, who is himself barking at me as he is in the process of
climbing into the car.

So that would be a yes.

Reading from Jim H and below why not get a Flickr or Picasa account and
stick them all up their?

Heh I would suggest reading the manual, but having read about five or six
for various models I won't say that'll be any help. They barely tell you
what the camera does let alone how it actually works :-)

Well yeah that'll do it :-)

Had a quick Google and it seems a standard multi-point focus with face
recognition. So it should spot faces and try to focus on and expose them
all automatically. I'd have thought that might cause a problem with delay
if you're moving, but your test photos look fine
