Digital Image Sensor Update



The Promise of Even Better Image Quality Ahead



by George Schaub

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
MP cameras deliver such good quality at such low price points that themegapixe...

The
Sprint PCS Samsung Multimedia Phone MM-A800



Much ado has been made of late of how camera phones will gut the lower-end digicam
market and how everyone will dump their 1-3MP digicams for these amazing multimedia
products. Having shot with a sub 1-megapixel phone a year back I shrugged and
moved on, deciding it was a fun toy that some might find useful but that image
quality was poor, even when compared with the lowliest of blister-pack dedicated
cameras. Word has gotten around that new, higher-megapixel phonecams are coming,
with 7 MP being the figure touted on one model available now overseas. In addition,
we just got word that Kodak is finally going to release their EasyShare One,
subject of a press conference last January, which is said to be a camera first
and then a web or phone connecting pictuire sender second. With all that in
mind I was intrigued by the new Samsung 2MP camphone sent to us by the folks
at Sprint, one that links up with Sprint's PCS Picture mail service.

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.
