Early Infrared

This is an HDR-photo taken in the near-infrared part of the spectrum. By blocking the visible wavelengths with an IR-filter, it is possible to record some infrared light during longer exposures. The limiting factor here is the sensors lack of performance outside it’s intended use, in addition to the factory default IR-cut filter overlaying it. But with six exposures (7.5s,15s,30s,75s,150s and 300s) added together, the result looks nice. Showing reflectivity that differs from the visible spectrum, as the colors actually continue beyond whats see-able by the human eye. For instance, the dark house in the center is actually white.

 

Another Awesome Long Exposure

A Composite of ~1000 individual pictures taken while driving. A photo taken every 2 seconds during a 30minute trip. This is another of those photos that illustrate what it would look like if you constantly had to see a longer time period of the world around you at the same time. I used the same car as my previous car shoot. (a Datsun 260Z 1973)

This photo was shot in 3D, below is the “Cross Eye 3D” version. (Right eye on the left image, left eye on the right, then focus) Click on the image to enhance.
This photo also work grate as a 16:9 monitor background. I might post a high-def version…

These photos are taken looking down the aperture of a 600/100 f/6 refractor, showing the the mounted guide camera at the bottom of the tube assembly. The below one shows a focused image reflected of of the CCD imaging chip, while its taking its own exposure. A picture showing a picture being taken, literally. Used the D700 with 50mm f/1.4G and 70-200mm f2.8G to obtain these shots.
