with Shutter Speeds
There are two ways to control light in photography—aperture and shutter speed. Put most cameras on Program, set a reasonable ISO to match the lighting conditions at hand and shoot, and you’ll get a reasonable picture. But as you know there’s more to both controls than controlling exposure—they have a profound influence on what could be called image effects. And those image effects are what can turn a recording into an interpretation.
is one part of the equation that determines depth of field, with focal
length and camera-to-subject distance being the others. Shutter speed
is a slice in the arc of time, with faster speeds creating thinner slices
and slower ones “fatter” slices. But in those larger chunks
of time something else happens—time is recorded in ways the unaided
eye never sees. It’s as if the camera can bring our perceptions
to another dimension, where time, space and motion begin to work in concert
and the “scan rate” of our eye is altered. Indeed, it’s
as if we had put a damper on our optic nerve, one that creates a delay
in the synapses but nevertheless keeps recording throughout the delay.
Truth in Journalism
an unsettling report on the radio last night regarding an awarding-winning
Toledo Blade photographer who recently resigned after admitting that he
digitally altered the content of a photograph that was published on the
newspaper’s front page. The image by Allan Detrich showed members
of a basketball team kneeling in prayer before playing their first game
since one of their teammates died in a bush crash last month. Detrich
used Photoshop to remove the legs of a person standing in the background
behind a banner.
Black and White “Conversions”
There are numerous ways to convert an RGB image to black and white in software. Depending on the program, its version and the level of your experience with it, you can make a simple color to grayscale conversion, make a simple “desaturation” click (which retains the RGB character of the image) or get involved with fairly complex, demanding and quite rewarding workflows. My interest here is with shooting raw and working with converters to get a good foundation for further work in black and white, or as a convert and print workflow without the intercession of further software tools.
This, the first in an exploration of these workflows, deals with some
of the tools in Apple’s Aperture. Like many programs Aperture
offers sixteen ways to get to the same place, and it’s a matter
of where you first saw it and how easy it was that makes you follow
one path or another. Here I’ll get into some of the controls
and tools; undoubtedly you will discover or have discovered others.
Today’s DSLRs allow for very high ISO ratings, with the newest featuring ISO 3200, and beyond. When shooting at these high speeds many manufacturers recommend, and offer Noise Reduction (NR) filters to help suppress noise. If you have worked at these high speeds, at what level of ISO do you find that NR filtration is important to retain image quality?
Briefly comment on your experience with high ISO settings and how you handle noise; mention your camera model in your comments.
