I had a friend that flew RF-4 in Nam. The unit unofficial motto was
"Kill'em with Filum". I think the official one was "Alone, Unarmed,
Un-afraid".
By the way I was US Army Artillery during the war and Medical Corps
after college on the GI Bill and an Army Scholarship to med school. We
call Army GIs or doggies, all infantry are grunts and artillerymen are
redlegs whatever the service. Marines are Jarheads or Gyrenes, Navy are
Swabs for the surface fleet or Squids for submariners and Airforce are
Flyboys or Zoomies. What is a zipperhead?
BACK TO PHOTOGRAPHY:
I've been checking on the web for infrared sources. Kodak
(www.kodak.com) has an excellent site with all the information on their
films. There are a few sites covering use of infrared, mostly from an
artsy viewpoint but a few had some good information
(www.mat.uc.pt/~rps/photos/FAQ_IR.html). One of the most interesting
included a section on editing digital images with Adobe Photoshop
(http://photo.net/photo/edscott). It seems this program can do a
considerable amount of image analysis including "spectral selectivity"
where each pixel is examined for intensity, color, etc and can be
isolated and or reassigned color, etc. This would serve to identify and
isolate parts of an image. I think this might serve to analyze an IR
image very nicely.
Apparently plants will vary dramatically in infrared images depending on
species and state of health or time of year so IR imaging should be a
very good biological survey tool. The real problem is going to be
getting good IR images with uniform exposures. I think I'll need to fix
the camera to the wing strut in a protective pod with the lense
prefocused at infinity for IR and trip the exposure with a release to
the winder. If I do a pod on each wing I could use the 2s for
extachrome and the OM-1 for IR and get replicate images for comparison.
I may have to land to change the shutter speed on the OM-1 but any
country road will serve for Tootie Mae. Determining correct exposure
seems to be the major problem for IR. Any suggestions will be
appreciated.
