The Gemini kit is composed of two flash heads (monoblocs) and a Gemini Battery
set, as well as a strong duffle-bag like carrying case and stands for the heads.
We worked with the 500WS heads, although the kit comes in both 250WS and 750WS
units as well. The supplied stands come with an "L" bracket that

There are times when you want your color to exactly match what's in the
scene, but for the most part color is a fairly subjective matter that can be
tweaked with ease in just about any image-editing program. Color has a hue--like
yellow, green or blue--as well as a vividness, which in photography is
often called its saturation. In addition, color can have a cast, which is influenced
by the prevailing lighting conditions when we make the photograph. That cast
can be influenced by the light source itself, such as photographing under direct
sun versus what we'd get when photographing under tungsten lights, and
by the position of the subject in relation to that light source, such as the
difference between photographing in the shade or open light. In addition, color
can also be influenced by the recording medium itself, be it film or digital,
and how the film is made or the digital image processor is programmed to change
the color during the recording processing.

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.

The New Pigment Ink Printers: How They Change Desktop Printing

by George Schaub

You wouldn't think that a small thing like changing the type of ink a
printer uses would have a profound effect on desktop photo printing, but that's
what the new products from Canon and HP might do. That change is offering pigment...

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.
