Infrared Photography

Infrared photography captures invisible form of light beyond the visible spectrum (or below the red). Digital cameras are converted to infrared or near infrared cameras by removing the hot mirror or infrared cut off filter that would normally block infrared. A different filter is added in the specific range of infrared light you wish to capture. Some infrared converted cameras can record a small degree of visible light in the red range of the spectrum to produce color or supercolor infrared, such as this image. Red and blue channels are flipped in Photoshop to produce a blue sky. Hues can also be adjusted.

 

 

*I shoot with super color infrared 590 nm with a Sony mirrorless camera- this adds some near infrared - to allow vibrant saturated color to the image mainly yellows and blues. Mirrorless cameras are best for infrared since they can focus on this invisible light better that normal DSLR's. The most common conversions are 720 nm or standard that record the red region of the spectrum which are then processed as a B&W image.

*Anything alive will reflect IR light - green parts of plants will appear bright white in near infrared - due to chlorophyll transparency in infrared light, most pronounced during spring growth.

*Wood's effect - foliage strongly reflects light causing dreamlike white foliage. And water or sky reflects infrared light to produce dark water and sky.

*Surreal effects can be produced which differ from those captured with visible light. Different tones are produced but also many challenges requiring extensive post-processing work!

External filters can also be used to produce an infrared image. However, since they block visible light long exposures, manual mode a tripod are required. Also the image must be prefocused before the filter is placed on the lens.

Infrared Photography is an experimental process of discovery! Hope you enjoy these new images.
