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.

Remember the shoebox, the place where all those snapshots were stored? It was
a great tradition to take a roll of film, share it with family and friends and
then dutifully deposit the pictures and negatives into a cardboard container that
would be stocked away on some closet shelf. Well, digital photography hasn't
changed that great tradition, but nowadays the "shoebox" is more likely
filled with CDs or DVDs that hold the pictures--only to be stacked away in that
same closet next to that snapshot shoebox.

The Case for Center Weighted Metering

by George Schaub

While today's multi-pattern metering system found in most DSLRs are marvels
of technology, you'll notice that almost every DSLR also has other metering
pattern options. The two main options, with variants available on some cameras,
are center-weightedaver...

The pixels that make up a digital image each have an "address",
a code that defines color, brightness and shades. When we make images with a
digital camera or from film with a scanner we are creating a matrix of pixels
that altogether create the illusion of a continuous tone image. These codes
are not dyes or even densities, but specific information as to how the computer
will interpret the colors and tonal values on the screen. It is only when we
make a print that we leave the "digital" world and enter the world
of dyes and pigments. Because each pixel has a code, basically a bunch of information
that is composed of bits and bytes, we can alter that code to change the "address",
or color and tonal look of every pixel. In this lesson we'll use the Replace
Color dialog box, found in most versions of Photoshop, or under other names
in other programs, to illustrate the point and give you an easy, fun way to
play with your pictures.

If you have Photoshop Elements or the full version of Photoshop
you can also use a tool called "Save for Web" to resize your images.
(Note that other programs might also have this feature under a different name.)
This is an automated way to get your images the right size for sharing. To get
to this toolbox just go to File>Save for Web, with the image already open
on your desktop.
