Backlight has been bedeviling photographers for years, particularly in landscape
pictures and those where you want to take a shot but simply showed up at your
location at the wrong time of day. Backlight in and of itself is not the problem;
it's how your meter behaves and how you make the reading that creates
it. Simply put, when the subject falls within its own shadow because the brightest
illumination is behind it the meter can be overwhelmed by the illumination and
"fooled" into thinking it has more light for the exposure than the
main subject dictates.

If you ever want a unique point of view try a "fisheye" lens. Like
looking through a door peephole (which in fact is a "fisheye" type)
this order of lens sacrifices linear correction in favor of a very wide angle
of view. Originally made for creating "full sky" images when pointed
straight up, they had long ago been adopted by photographers for creation of
decidedly different points of view, and, today, even doing QuickTime movies
to display the interior of a condo or vacation home.

All the talk in the past was about megapixels, with the horserace of ever-higher

Now I know how stagecoach drivers felt when they saw those first rail lines
being laid over their routes. The recent announcement that Kodak would be discontinuing
their silver black and white papers didn't come as much as a shock as
an inevitability that one always hopes will not be manifest. With inventories
expected to last a few months, we're now witnessing the disappearance
of venerable brands such as Polycontrast IV, Azo and Polymax Fine Art, Kodabrome
II and Portra, even their "Digital Black and White" paper, which
was used for digital printers. According to a Kodak spokesperson, Kodak has
seen a cumulative drop in black and white paper buying of 25% per year over
the past few years and could no longer justify being in the market. We also
learned, by the way, that Kodak black and white papers had of late been produced
in Brazil, being packaged from rolls in Rochester. The spokesperson did stress,
however, that Kodak black and white film and chemistry was not on the chopping
block and that Kodak sees silver photography as still extremely viable.

One look at the specs of this new Tamron zoom and you'll understand why
it's immediately attractive to anyone carrying around a digital SLR in
their day bag. Weighing in at around 15 oz and measuring just under 3x3.2",
the lens is quite the marvel of size for what it delivers in focal length and
aperture options. Indeed, if someone told me that a constant aperture, 17mm
wide lens would be this size a few years back I'd have thought they had
lost their optical marbles. To be fair, however, that 17mm is not really a 17mm
in 35mm equivalent, thus practical terms, and I wonder why lenses like this
are still labeled that way. This lens is only for APS-C sensors, which means
it has the "35mm equivalent" of a 27mm wide angle view and 80mm
tele.


Tamron's new 17-50mm zoom, available in Canon, Nikon, Konica
Minolta (read Sony), and Pentax (read Samsung) mounts is highly
portable and compact.
