Introduction and ? about Digital Infrared Photography

["Brad" <brad@xxxxxxxxxxxx>]

Hi all,

My name is Brad Barden and I have been lurking
for a few weeks, so it's time for an intro.

I have been into photography most of my life,
and graduated from Brooks Institue in 1979.
I have messed around with infrared off and on
over the years, without much satisfactory success.

Currently, I own a small graphics shop and we
do offset printing, vinyl sign graphics and web
page design.  I hardly do any photography at
all professionally any more, it's just a hobby;
and after years of trying to make a living off
of photography, I can finally say I am beginning
to enjoy it again.

I recently bought a used digital still camera, a
Kodak DC120.  I am thrilled with the picture
quality, especially for internet use, and the instant,
feedback, and lack of expense for film and processing.
You can see a some recent pics (not infrared) at:

After getting some spam for the following site:

http://www.kaya-optics.com/

They are selling a filter for cam-corders and 
digital cameras, anything that uses a CCD 
(charged coupled device) for $120+.  This
filter allows the camera to see through tight and
thin clothing.  My thought was that it was an 
infrared filter, and what a scam this was.  I hadn't
looked into the prices of filters lately.

Anyway, the practicality of using such a filter in
every day shooting situations is ridiculous, long
exposures . . .  etc.

But, my thoughts turned to simple hobby
infrared digital photography.  I searched the web
and only found one page, by Eric Cheng.  His 
page offered some good examples, but little technical
info.  I wrote to Eric, and he agreed that their wasn't
much info out there, that I might have to open the 
camera and remove an infrared blocking filter.  I
wasn't too keen on that.

Just in time, Todd Martin offers some 87C filters
for sale on this list, and I received mine on Saturday.
I tried it out on a hazy sunny but windy day.  It worked!
The evergreen trees I pointed at turned out snowy
white, though somewhat blurry due to the wind.  My
exposures were from 1/4 sec to 2 sec at about f2.8.
Normally the camera is rated at 160 ISO.

This camera has it's limitations; although it does allow
manual exposures, you can't select the f-stop and shutter
speed independently.  AND it only does auto-focus, except
in macro mode.

Has anyone else out there had any experience with this
stuff?  My apologies if it is an old topic.
