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.

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.

The Samsung NX100 is the compact version of Samsung’s new NX-CSC-system. The camera has a retro design that looks like a classical view finder camera but is a modern digital system with a large LCD screen on the back. The superb AMOLED screen uses 614,000 RGB dots and displays a very brilliant image. The camera offers a standard accessory shoe on the top and a special digital interface right below the shoe. Samsung offers a lot of accessories for the N100: The most important attachment are the optional electronic view finder ED-EVF10, the GPS-tracker ED-GPS10 and two flash systems.

First Look: Canon Digital Rebel XTi

by George Schaub

The Canon Digital Rebel line accomplished a number of things. It broke the
$1000 DSLR price barrier, with room to spare, and as a result brought DSLR photography
into the mainstream. What followed is history, with other makers bringing forth
their "bargain"...

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 Leica X1 looks like an analog camera. It has a compact body with a high quality finish and offers two setup dials on the top. If both dials are set to A-mode the camera will set aperture and shutter speed value automatically. If the photographer changes the aperture setting manually to a value between f2,8 and f16 the camera will work in aperture priority mode and set up shutter speed automatically. Similarly, a change of the shutter speed dial and setting the aperture-dial to A will switch the Leica X1 into “shutter speed priority mode. It’s a very efficient and easy system. The camera doesn’t offer any scene modes.

The X1 is Leica’s newest compact camera. It is based on an APS-C-sized image sensor and a lens system with fixed focal length with 36mm (35mm film equivalent). The camera has a small and compact body, offers easy handling and creates very crisp images.
