No. 34. Backyard Infrared

  • Backyard

  • Dogwood and South Tree Line

  • Tall Grass in Rock Garden

I recently acquired a new “full Spectrum” camera for shooting infrared photos. My old converted Pentax K10 gave up the ghost some time ago. The K10 had been modified to capture infrared wavelengths at 720nm and above. I had it converted to IR after it had spent several years on the shelf.
This new camera is a virginal Canon point-and-shoot modified by Kolari Vision. I captured the above images in my backyard with a 590nm filter and processed them using Kolari’s channel switching software. This little bit of code swaps the red and blue channels resulting in a deep blue sky (and shadows), rather than a yellow-red sky.
This little camera came with 590nm and 720nm filters as well as a Hot Mirror filter that blocks IR and allows shorter wavelengths to impinge on the sensor, thus allowing color capture. (Other IR filters are available.)

No. 4. Blue Sky, Blue Snow Infrared

There is no color in the infrared spectrum. However, some color artifacts may be captured by infrared cameras depending on the light-blocking filter installed on the camera’s sensor. My camera blocks visible light below 720 nm. This allows me to capture just enough of the red spectrum to switch RGB channels to achieve the “Blue Sky Effect.”
