Overall Image Quality
A tiny camera with big camera performance. Ok, it's not
as sharp as its Carl Zeiss clad brothers the S70 & F505V but for its
size the P1 packs an image quality punch to put many bigger cameras to
shame.
Metering was impeccable, exposing the scene perfectly without
loosing any detail in shadows or blowing out light areas... That 12-bit
DAC provided a large dynamic range time after time, although the LCD is
a little deceiving, while out shooting it appeared as though many shots
were over exposed, on return to "base" checking the images on
a computer monitor it was apparent that the P1 had captured much more
than we'd expected. Indeed the P1's images reminded me of the "compressed
dynamic range" you'd expect from a Pro SLR.. Looks like Sony have
been tweaking their image processing algorithms.
Colours were excellent, "pleasing" but not fake
or over saturated. Metering was on the whole very good and with the choice
of spot metering and twilight exposures if you need them you should be
able to shoot in pretty much any situation. That's not to say the camera
is completely flawless, read on...

Purple Fringing (Chromatic Aberrations)
A consequence of packing a 3 x lens into such a small space,
something had to give. The P1 suffered from fairly pronounced chromatic
aberrations (purple fringes) on wide angle shots. This, confirmation that
the problem is simply the interaction of the lens (not Carl Zeiss this
time, but a Sony lens) with the microlenses on the CCD made worse by the
effects of blooming (overflow of charge from one pixel to the next). Zoom
in a little at these aberrations disappear.
There are several techniques to avoid / remove this: (a)
use a negative exposure compensation to reduce the effect, (b) zoom in
slightly where possible, (c) use a third party application to remove the
chromatic aberrations.

| It's a shame because I
quite like this shot, of course I never saw the aberrations reviewing
the image on the LCD screen, if I had I may have retaken with a -0.7EV
compensation which would reduce if not totally remove them. |

| A perfect example of chromatic aberrations,
and fairly extreme. Last time I saw aberrations like this the camera
had C-3030Z written on the side. |

Barrel and Pincushion Distortion
The P1 has the "normal" (it's a shame we're even
aware of a normal) amount of barrel distortion and very little pincushion
distortion. On the whole it's a pretty amazing feat for such a small lens
system. Distortion calculated as the amount of distortion to the horizontal
line (from left or right to its center) as a percentage of image height.

White Balance
Just as with the S70 I find the P1 White Balance control
leaves a lot to be desired. Offering only four options: Auto, Hold (freeze
auto white balance at current reading), Indoor and Outdoor. This makes
getting the right white balance a bit of a point and hope affair, I personally
would have preferred the standard Incandescent, Cloudy, Sunny, Fluorescent
(1, 2 & 3) and (now that we've seen it on the Coolpix 990) fine tuning
of white balance. (Sample images below recorded at 1280 x 960)
