Extensis Inc. has announced an update
to its Pro Photo Raw Image Filter for Portfolio 7. The updated filter will be
a free upgrade for registered owners of Extensis' digital asset management (DAM)
solution for organizing digital photos, illustrations, page layouts and presentations.



With the Pro Photo Raw Image Filter, Portfolio generates high-quality thumbnails
and previews from the unprocessed raw image files created by professional digital
cameras from Nikon, Olympus, Kodak, Canon, Fuji, Konica-Minolta, Pentax and Imacon.
With the Pro Photo Raw Image Filter, Portfolio 7 can extract EXIF metadata and
IPTC from the Raw files, create thumbnails for displaying the images in catalogs,
and generate high-resolution JPEG previews on the fly for detailed viewing, printing,
slideshows and QuickTime movies.



The Pro Photo Raw Image filter for Portfolio is powered by technology from Bibble
Labs.



The following cameras and file formats are supported by the updated Pro Photo
Raw Image Filter for Portfolio 7:



Nikon - D1/D1x/D1h/D100, D70/D2h

Fuji S2 Pro/S7000Z

Westcott has recently made a new addition to its line of Soft Box Light Modifiers
by introducing the New Masters Brush. The New Masters allows users to create more
defined shadowing, which enhances depth and adds contour.



Westcott worked directly on the design with Master Photographer Ken Cook, a third
generation family studio owner with over 50 years of experience. The specially
designed multi layer front panel along with the Barn Door and internal baffle
creates a 2 f-Stop differential between the center or the heart of the light and
the outer edges. This allows users to achieve the lighting patterns created by
the old Masters of Photography using split, broad and short lighting, including
all the variations of Rembrandt and Butterfly Lighting.

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.

For those who have been working with the latest digital cameras--both
integral and interchangeable lens types--you've probably seen an
option called Raw among your file formats. Unlike JPEG and TIFF, Raw is not
an acronym and therefore we don't capitalize it, and is just what it states--the
"raw" image date received by the sensor and digitized within the
microprocessor of the camera. It is not "raw" in the sense that
it is unfettered or unrecognizable, but it does take image processing software
other than what's in the plain version of some image processing programs
to see it. That Raw software converts the Raw image file format to an image
on the screen and allows you to save it to a format other than Raw--such
as TIFF or JPEG.

High scene contrast always creates difficulties for photographers, whether
shooting film or digital. The difficulty stems from the difference between the
ways the film or sensor "sees" and how the human eye sees. Our eyes
are adaptive, and can resolve large variations in brightness by the way it scans
throughout the scene and the amazing reflex of automatically restricting and
dilating the pupil to adjust to bright and dark areas before us. While light
metering systems in cameras are impressive in the way they can read light, the
fact remains that at the moment of exposure the lens on a camera records a scene
at one fixed aperture, or opening. In most situations this is no problem, as
the meter averages light values and the bright and dark areas are distributed
through the recording medium properly. But high contrast presents a problem.

A
better solution is to use the --1 contrast setting. This
allows for smoother tonal gradations and addresses the need to
control the divergent light values in this backlit scene.

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.

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" DSLR offerings, with the Rebel setting the bar.
As is their wont, Canon followed up on the Rebel with other generations of this
successful product, each one a modification that incorporated technology gotten
from more current cameras and lessons learned from past Rebel products. The
latest of these is the Canon Rebel XTi, a 10+ megapixel DSLR with a dust reduction
system and simplified operating system.

The Panasonic DMC-L1 DSLR is Panasonic's first digital single lens reflex
camera. Priced at just under $2000 with a Leica D Vario Elmarit f/2.8-3.5 14-50mm
zoom lens (equivalent to 28-100mm in 35mm format) and 7+ megapixel sensor, it
is a member of the Four/Thirds family. That allows you to use any lens from
the Olympus and Sigma 4/3 mount offerings on the camera as well. It uses SD
cards, and takes the newest SDHC cards with greater storage capacity. And the
Leica lens uses Panasonic's OIS (optical image stabilization) that helps
you get steady shots in two to three less stops of light than usual when shooting
handheld. The body also has a Live View mode similar to the feature found in
Olympus' recent DSLRs.

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.

There was time when those seeking super-wide lenses for APS-C size sensor cameras didn’t have much choice, but new light gathering systems that distribute light evenly from lens to sensor, as well as new optical formulas from camera makers and independent lens manufacturers, have changed that point of view. The latest in this welcome new class of glass is from Tamron, with their 10-24mm f/3.5-4.5 offering. Priced at around $500 (street) and weighing in at about 14 oz., the Tamron 10-24mm is useable for cameras that require “motor in the lens” operation, such as the Nikon D40X, on which this lens was tested.  The DiII designation tells you that this lens is for digital SLRs with APS-C sensors.
