These are not just photoshoped images, although there is alot of work done in photoshop to get them to were they are. I shoot digital and these images "are" recorded in the Near IR 0.75–1.4 µm wavelength . This is not a adjusted image from the visible light spectrum. They are also not thermal, thermal imaging records the electromagnetic radiation of a wavelength longer than that of visible light. Basically I am recording the same light that your remote control emits, that you cant see.
If you want to see exactly how I make these images you can view my post in the AllNikon forums here: http://allnikon.proboards86.com/index.cg...
In fact, the picture is a visible light image, but corrupted by IR damage.
These types of films are often sensitive to ultra-violet AT THE SAME TIME.
And as I stated above, the artis in this thread WAS NOT USING IR FILM. THESE ARE NOT IR PHOTOGRAPHS.
And no, they aren`t negative.
They are, in the artists words, the result of a color limiting filter, and a channel swap and white balance adjust performed on a digital camera.
INFRARED IMAGERY DOES NOT EXIST IN PHOTOGRAPHY. When you see an infrared image, what you are seeing is an artist`s conception, an ANALOGY.
Basically, they have related different frequencies of IR to the frequencies (frequency=color) that we see. The final image is in visible colors, and therefor, not in IR `colors`. It is an analogy.
IR photography seperates frequencies of IR into ranges of visible light in such a way as to make it medically or commercially useful.
No on tries to make a very houghtful analogy. No one tries to make the colors match of meaningfully.
THIS IS NOT IR PHOTOGRAPHY. This shows a widerange of coloration that macthes natural visible coloration.
THE ARTIST USED A FILTER AND ADJUSTED THE WHITE BALANCE OF NORMAL FILM andnormal color image
I`d like to see what it actually looks like when you photograph faces with infrared film.
It doesn`t have anything to do with heat, it`s infrared light which is slightly above what humans can see.
the photographer could have altered the scale at which the heat "shows up." Its more art than science for this post. The artist did it to make cool pictures not to study what the heat output of certain organisms are.
Ah so it is those pictures where it shows heat. I thought white meant really really hot though. Grass wouldn`t be that hot- maybe you can change what colour is what heat though.....

That`s what i thought o_0....
The trees are white because in life they are green - making the foliage reflect infrared strongly. But in most infrared photography there isn`t any blue (it turns reddish) so I`m not sure if these haven`t been photoshopped.
