Finland in infrared
@ 8:23 pm Did you know that most digital cameras can “see” well into the invisible infrared range? Try taking a television remote control and watching it with your camera while pressing one of the buttons. The same is true for video cameras. Most of them have filters to filter out most of the infrared. Some video cameras have a night shot mode, which when activated, removes the infrared filter. These can’t really be used during the daytime without a filter to filter out the visible light because they get saturated. The manufacturers were worried people were using them to see through peoples’ clothing, since at infrared wavelengths some clothing is transparent. Some things that are black in natural light are bright in infrared. In infrared you can see through liquid black ink and camera negatives which look black in natural light. Here is a YouTube video that tells about the effect and how to make your own filter. Don’t confuse this with far infrared, which you can feel with your skin as heat energy if it is intense enough, or see with a thermal imaging camera. Near infrared is more like visible light – you just can’t see it very well or at all depending on how far the wavelength is from visible light. Ansel Adams is a famous photographer who lived in America who stumbled upon this phenomenon. He took black and white photos, many from the Western United States. He often used a dark red filter, because it gave good contrast.
I used the method and took the following pictures of my yard. The near infrared photo is fuzzy because it is filtered through 5 layers of picture negatives.
