May Workshop Meeting On DOF
Members practiced their control of image focus
Warren Bailey conducted a hands-on workshop for members.
They had the opportunity to shoot several setups including flowers and
still life arrangements. Some members shot hand held and others used
tripods. The exercise was to take the same shot with varying f stops
(from f 2.8 to f 32) and view the results either in camera or projected
to the screen. The workshop provided a useful learning experience for
the participants.
Before the meeting members enjoyed refreshments and
conversation. Munchies and drinks were provided by Doreen O'Connor,
Erin Lamb, and Jackie Greene. Thank you!
Other Meeting Details
Wayne Hall reminded members that the Sudbury
Valley Trustees Annual Riverfest Photography Contest will
accept framed print entries through June 5 at the SVT headquarters
in Sudbury. Details about the competition may be found at the SVT website.
Henry Weisenberger encouraged
photographers to atted the NECCC (New England Camera Club
Council) Conference, to be held on the campus of U/MA Amherst
on the weekend of July 10 - 12. He passed around a conference
flyer and directed members to full information at the web site, where you can
register for the many programs, photo ops, and competition
opportunities. Vendors will have a roomful of bargains for
purchase. As many as 25,000 have attended the NECCC conference in
the past, and around 12,000 are expected this year.

Report:
Field Trip to Newburyport Saturday, May 2
Carol Walsh led an all-day field trip to Plum Island and
Newburyport, which included a morning stroll on the beach and a sunset
supper at Bob Loster. She and the other photographers, Sue
Abrahamson, Betsy Moyer, and Marilyn Tromer, will give a full program
at the SVNP meeting on July 9.
If you have an idea for future field trips please
email Carol Walsh at
clesliewalsh@hotmail.com. She
is keeping a "running list" to see which places are
appropriate for the season and how many members are interested.

High Dynamic Range Photography
Have you experimented with High Dynamic Range
(HDR) photography yet? Digital imaging has made it much easier and
Photoshop CS3 and CS4 include support for it. There are also
plug-in/stand alone versions of downloadable software (Photomatix Pro 3, for
example, which offers an indefinite trial but places a small watermark
on images) that provide more extensive support.
Wikipedia includes the following
about HDR--
"In image processing,
computer graphics, and photography, high dynamic range imaging (HDRI or
just HDR) is a set of techniques that allows a greater dynamic range of
luminances between light and dark areas of a scene than normal digital
imaging techniques. The intention of HDRI is to accurately represent
the wide range of intensity levels found in real scenes ranging from
direct sunlight to shadows.
"High
dynamic range imaging was originally developed in the 1930s and 1940s
by Charles Wyckoff. Wyckoff's detailed pictures of nuclear explosions
appeared on the cover of Life magazine in the mid 1940s. The process of
tone mapping together with bracketed exposures of normal digital
images, giving the end result a high, often exaggerated dynamic range,
was first reported in 1993, and resulted in a mathematical theory of
differently exposed pictures of the same subject matter that was
published in 1995 by Steve Mann and Rosalind Picard. In 1997 this
technique of combining several differently exposed images to produce a
single HDR image was presented to the computer graphics community by
Paul Debevec.
"This
method was developed to produce a high dynamic range image from a set
of photographs taken with a range of exposures. With the rising
popularity of digital cameras and easy-to-use desktop software, the
term HDR is now popularly used to refer to this process. This composite
technique is different from (and may be of lesser or greater quality
than) the production of an image from a single exposure of a sensor
that has a native high dynamic range. Tone mapping is also used to
display HDR images on devices with a low native dynamic range, such as
a computer screen." Click for more information at Wikipedia.
If you would like to set up a
local in-the-field experiment to capture some shots to tone map
into an HDR image, please contact Bob Diefenbacher by email or phone
(978) 443-0014.
