The III also sports a new Raw option, dubbed sRAW, which is 2.5 megapixels
in size and half the file size of "regular" Raw images. The advantage,
claims Canon, is that sRAW images can be processed just like any Raw image but
stored in at a smaller size. This is perfect, they say, for wedding candid photographers
who want Raw post-exposurepr...

The promise of digital imaging is that you can get one-touch corrections on
your photographs, making it easy to create the best images you can from every
picture you take. The phrase: "I won't worry about white balance,
exposure or contrast, etc....I'll fix it in Photoshop" is commonly
heard, but it isn't always the best course. If you shoot in Raw mode you
can fix anything, even exposure compensation, later, but not everyone wants
to go through the steps of working with Raw converters and all those sliders
and options. That's where the supposed magic of "auto" fixes
come into play, and yes, there are times when it can do wonders. Today, cameras
even have auto red-eye fix and amazing adjustments for backlighting problems.

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 Originally made for creating "full sky" images when pointed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.

The Promise of Even Better Image Quality Ahead

All the talk in the past was about megapixels, with the horserace of ever-higher
counts grabbing all the headlines. Some folks claim that the latest 6 and 8

Today's cameras are microprocessors with lenses. Most of us know how
to change color, sharpness and contrast, and even ISO settings, for every frame
we shoot, but did you know that you can also change how your camera's
dials and buttons work? By using Custom Function settings you can alter the
function of all those dials and buttons and personalize them to the way you
work, or to each unique shooting situation. When the camera comes out of the
box it has certain "default" settings, those chosen by the camera
manufacturer. While there is a certain wisdom in the defaults, they are not
necessarily the best way for your style or shooting needs.

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.
