Infrared R72 82Mm Filter

Hoya Infrared R72 82mm Filter Review
Infrared photography is based on a simple law of physics: different wavelengths in the distribution of light. The human eye detects light between 400 nm and 700 nm
can see the spectrum between wavelengths. Infrared filters filter 700 nm to 1200 nm, which are outside the visible spectrum of light.
These are special filters designed to pass wavelengths between 700 nm and 1200 nm wavelength range as the near-infrared region.
It is within the so-called region and does not contain the far-infrared area (around 3000 nm) called "thermal emission". Thermal imaging
It is a much more complex imaging method and Infrared photography does not cover this imaging method.
PRODUCT FEATURES Trees and greenery will take on a color close to white. The contrast between the sky and clouds will increase significantly. The sky will turn a color close to black> The water surface will turn a dark color close to black>Human skin will take on a very smooth, soft appearance>The human eye retina will become clear>Reflections in buildings with glass on the outside, such as skyscrapers, will have a different and interesting appearance than what is seen with the naked eye.
