this is a series of photos taken using an Infrared filter
and digitally retouched in Photoshop.

HOW IT'S POSSIBLE?
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengthsused for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red).
"Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.
