Infrared

[Kentucky Kache]

Does anyone know if they make a simple infrared lens? Nothing computerized, just a carry item.
I guess the closest thing would be the scope used by deer hunters.

Actually... I just read the other day ... that you create a homemade IR lens for your digital camera with film negatives...

I'll dig up the weblink if you are interested...

I dont think that it works for anything else, except digital cameras... (using a CCD)

Take a cheap digital camera off ebay for 25 bucks and make it a digital IR camera!

... there's one solution... but sorta computerized... eh?
(portable all the same!)

I already have the cheap digital cam. Looking forward to your post. Thanks.

Link to Website... It uses a webcam but digital cameras are the same...

Slashdot article...http://hardware.slashdot.org/article...tid=159&tid=14
This is where I saw the link .... there are some people that comment on other similar projects... with links...

If you build one... post a pic...

This seems to be for night vision only (near IR). What I am interested in is seeing the color coded temp. differentials, for locating old foundations/roads, etc. (far IR). I guess what i want is way too expensive.
Still, nice site. Thanks.

Kodaks New IR Film, the b/w, and a # 25 filter, will do what you are asking!
Like anything else, It does take reading the Kodak IR Book(s) and lots of practice !
The new IR Film is a lot easier to use then the old IR Film was!
ONLY! One problem...You have to find some one who knows how to develope the IR Film!
Your local Wal Mart can't!

Jbot:
It all depends on what you're looking for!
I use an airplane, to fly over and to photgraph the mnts & desert for any area, that may have the sites that I am looking for!
You can rent a plane, w/a pilot depending on your locale, for about, $100.(?) an hour or so!
ME!
I just "Badger or Entice" my Younger Bother, into flying me around!
BUT!
Even then, you MUST learn how to take photos from an airplane!
There's no such thing as, "Plug & Play" about it !

jbot...sorry for the late reply on this thread. I purchased my aerial infrared microfiche from a government agency, located in South Dakota. The IR taken from 20,000 foot worked the best, for my application. You could plainly see stagecoach and buggy ruts, as well as foundation impressions. I was looking for early bridge crossings, and had great success, thanks to the aerial infrared.

A) Excellent post SWr, I am in total agreement.

I have used it to locate old mission sites due to the different compactness of the ground.

I would like to add somethng,

IR is effectively heat so you have to protect the flm fro any source of heat.

It cannot be handled or developed just like any ordinary film. Cool is the word.

Great thread guys on IR and Thermal photography... I would like to know your opinion on Aura flashes off of gold caches.. First do you believe in that technology and if yes! .. is that considered IR technology or thermal or something else... I have an Ex partner who has that technology and I have seen his pictures. but he would not divuldge much information on the subject.

SWR - Any more info. on that gov. agency in South Dakota?

Dawgvader:
What you are referring to is, The "Aura"! is done with an "SX" Polaroid Camera
I have a book (around somewhere) on it and a couple of really weird pictures, showing an "AURA", that I took !
If you want more info, drop me a line!
