Anyone experimented with infrared cameras?

I doubt a mere filter will produce all the results wished for, you wanna send out some IR light as well.

Man but I dig that music! Bipdipdeep, dapbabdap. Chihichikichun...

By the way, many cameras with built in IR vision may send out light, but have the frequencies that those special bikinis become transparent with stripped out. Too bad huh? But wait a second.. is it really naked skin they want to keep from us?

I like that video. Thinking about giving it a shot, though I'm not sure how well that filter will actually work.

Infrared is a spectrum of light beyond that which we normally see.
Despite having an IR blocking filter installed between the lens and the CCD, most digital cameras still react to some near infrared energy, though at levels far lower than visible light.
To take “infrared” pictures—i.e., photos primarily made up of near infrared energy—you need to filter out the visible light and only allow the near infrared and infrared spectrum through to the film or sensor.
You don't need to send any IR light out. You only need an infrared filter. (or a expensive IR camera)

Hints:

- There is more infrared light around when there is bright sunlight. This doesn't mean you should avoid using IR in other conditions but that the effects are stronger when the sun is out.
- Largest amount of IR: the hours just after sunrise and before sunset (due to the angle of the sunlight through the atmosphere), the effect is most dramatic (i.e deep black sky) when photographing with the sun behind the camera.
-An electronic or bulb flash will increase the amount of IR as well as visible light.


Infrared do not records heat.

This is a common myth - that since heat output is a kind of infrared radiation, then infrared film or CCD must detect heat, such as human body heat. This is essentially incorrect. Thermal radiation will not be recorded by infrared film or sensors; they are not sensitive to a long enough wavelength to show such things as heat patterns.

Sorry, I was thinking you're interested in nightvision, but of course that's another story.
For the stuff that Ed Grimsley does, do you think a simple IR filter would do? Do you know which frequencies are usually stripped out of conventional night vision.

The difference is I'm used to video cameras, you're talking about taking stills.

Night vision can work in two very different ways:

* Image enhancement - This works by collecting the tiny amounts of light, including the lower portion of the infrared light spectrum, that are present but may be imperceptible to our eyes, and amplifying it to the point that we can easily observe the image.

* Thermal imaging - This technology operates by capturing the upper portion of the infrared light spectrum, which is emitted as heat by objects instead of simply reflected as light. Hotter objects, such as warm bodies, emit more of this light than cooler objects like trees or buildings.

Well, most camcorders have Image Enhancement if anything, and some of them add an IR light 'beam'... now can I capture ufos with only that?

Grimsley is on Therman Imaging is he not?

Tried the remote control thing with my camera and it can detect it. I just don't think that it has a black and white mode. Can't find the manual to check and see.

video cameras = look for 'nightshot' or '0 lux' option (or something similar)

the IR beam that cameras send out is used for autofocus only...

in order to capture ufos you'll need three things:

1- a camera with a CCD capable of seeing the infrared light spectrum

2- a filter for stopping the visible light and only allow the near infrared and infrared spectrum to pass thru (some cameras has it build-in)

3- a lot of luck

[nagual]

ummm... ok..., if you are talking about regular CCTV cameras -infrared security cameras- that send out infrared light, I don't think you can see ufos with it, because the subject must be within the range of the LEDs lights.

The camera has infrared LEDs installed around the outside of the lens. This lighting allows the camera to capture a good image in no light at all, but the range of these LEDs is about 1,5 to 3 mt. ( very expensive ones 10 mt. )

For ufos, a regular home video camera will do (with manual focus option is better), and the best way is shooting in broad daylight, filtering out the visible light and only allowing the near infrared and infrared spectrum through to the film or sensor.

Thank you for your responses, nagual - I clearly have my work cut out for me...
