    Above 720nm of wavelength visible light enters into the realm of the invisible infrared. Though undetected by the human eye it can still be recorded by film that is sensitised to these wavelengths. The other worldly quality revealed in these images can hold a special beauty. The images in this series are taken by placing a filter over the lens that is opaque to visible light and only allows the infrared through to the film. the two films I am currently using are ADOX IR820, which is sensitised up to 820nm and Rollei IR820C, also sensitised up to 820nm. The Rollei film also states that it has a reduced anti-halation backing backing which can produce aura effects with long exposures (anti-halation backing is normally included in films to prevent light reflecting back from the rear of the film [...]
