D800 pictures from outer (infrared) space

On hi-radiation days we use to meet here on the pier, if the black tide did not cover everything.

The older ones prefer to hide in the black shadows of the wide reflecting trees.

We know that one day we will go back where we belong to. When we will understand the meaning of this mechanical giant, we will finally go home.

The lake of Zurich as the human, no-infrared eye cannot see

Enjoy full size view by clicking on each panorama.

Slightly more than half of the energy from the Sun arrives on Earth in the form of infrared radiation. Water absorbs the infra-red radiation, that explains the black lake and forests under the clouds.

The different pigments in plants reflect, transmit, and absorb different portions of the near-infrared radiation that we cannot see. Some plants can reflect more than others.

The clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to the atmosphere. Enjoy the reflecting trees and clouds: can you find the snow reflecting infra-red in the background?

The artistic side of infrared photography with a 850 nm filter and the Nikon 50 mm f/1.4 G

Enjoy some views of the Botanical Garden of Zurich through the 850 nm infrared filter I recently got.

These pictures were shot without focusing through the IR filter but removing it, focusing and remounting it.

They are quite soft because of the AF system calibrated not for IR light but for visible light…

… nevertheless, these pictures are still giving some thrills, don’t you think?

Click pictures to magnify. Btw, plants reflect IR light, that’s why they are so white…
