Because the chip size of the digital SLR is slightly smaller than the
35mm film format, there is a slight difference in the perception of the
focal lengths. The Tamron 28-105mm f/2.8 becomes the equivalent of a 42-158mm
lens. To determine the focal length in the case of the S-1 the chip size
factor is 1.5, so to determine the focal length one multiples the focal
length by this factor. There is a chart with the conversion on the Tamron
web site (www.tamron.com)
for most digital SLR cameras.
Getting a clear sharp image is so critical because it gives you more options
in postproduction. With tools such as Photoshop, no longer do you have
to make all of your decisions while you are shooting. With a clear crisp
image one has the option to blur, manipulate, and retouch later. Having
a clean file allows you to spend the time on enhancing your image rather
then trying to compensate for exposure or sharpness.
Nik Color Efx Pro! is a digital filter system that plugs right into Photoshop
and gives you the option to add color gradients and grain, soften and
shift colors. The interface is designed from the perspective of a photographer
adding filters to their lens, making it extremely simple to use. Because
all of the filtration is digitally done in postproduction, there is the
advantage of practically limitless options. One of my favorite filters
is called Monday Morning (sepia). It increases grain and allows for blurring
without making your image look out of focus. It also removes the majority
of color. The amounts of blur, contrast, and color are all separate so
you can fine-tune the effects to your taste and create your own style.
Many of my images wind up looking like paintings. The texture that they
transmit is due in part to the addition of filters, but it's largely
a function of the lighting and grain, and not because I applied a "painting
filter." They are unique images that transcend just photographs
of people dancing, but their warmth and treatment help emote the tone
of the piece. No photograph of dance can tell the whole story. Years ago
when Martha Graham was asked to describe her dance, she responded by saying
that if she could put it into words then she wouldn't have to dance
Dance photography is a dialog that references dance but also focuses on
form and frozen moments that never quite do justice to a medium based
on time and visceral experience. Additional effects can also enhance the
painterly quality with the use of digital filters. With all of the latest
and greatest technologies there is a great potential to expand your creative
