Flash - You've got six shots. Take one with a flash,
then take the exact same thing without using the flash. Exercise
your ability to show the strengths and weaknesses of creating mages
by using (or not using) a flash, using all the lessons we've learned
in photographic composition and technique.
CAUG Digicam SIG
November 12, 2002
Program notes by Dauris Granberry
The Digicam SIG met Tuesday, November 12, at Parkdale Library
with fourteen photographers attending. Our assignment
was to take photos of three subjects, both with and without
flash. Bruce Switala's photos were taken in his yard,
beginning with the seedpods of Golden Raintrees. From
his photos, we learned that colors are changed by flash and
that flash photos are often sharper, particularly in low light
situations. In one photo where part of the overcast sky
was in view, we could see how the light from the sky had cut
back the exposure leaving the plant in the dark. In his
second shot, the flash illuminated the plant and corrected
the exposure. These photos illustrated the joy of digital
cameras in that one can see each photo and make corrections
until the desired effect is achieved.
Joan Stephens brought photos of items from her Mexican
collection taken indoors with tunsten lighting and with flash.
From her pictures we learned that indoor lighting produces a
warm orange light and using flash made for truer colors.
Flash, however, tends to create glare or bright spots on many
reflective surfaces found inside our homes. By taking
photos from an angle one can sometimes avoid the reflections.
Again, the flash made for sharper photos than the hand- held
camera in the lower light indoors. Joan's delightful
solution was a lovely picture of objects illuminated with
candles. Again, with digital cameras we can experiment until
we find the answers.
John Hoffman and Patty Beasley repeated their photos from
October as many of us had not seen them. Patty also
showed us beautiful pictures taken in Carlsbad Caverns, some
with an infrared option on her Sony camera. She also
shared some beautiful landscapes from her trip to Colorado.
Stitching photos to create panoramas was demonstrated, first
by Bruce who used pictures of the local toronado
destruction near his home. Stitching photos together gave the
viewers dramatic closeup views of broken trees and damaged oil
storage tanks. Bruce used Encore Stitch and HP Arksoft.
Patty Beasley then gave a demonstration
of the Jasc Aftershop stitching program. First, she
showed five photos of a long Native American ceremonial pipe
that she took by beginning at one end of the pipe
and overlapping each additional photo by 1/3 without changing
her position or the zoom or focus ( locking the exposure
if possible). Within the program format, she arranged
the photos in order and with what seemed simple steps, the
software stitched them together one at a time. Quite
