Challenge has finished
Photographs of any kind of subject taken with the aid of an infrared filter. You MUST have used an infrared filter to achieve your result, and you MUST give details of the filter in the notes to your entry (eg: Hoya R72, B+W 093, Link Delight IR720). An infrared filter typically screws or slots onto the end of a primary lens. It aims to filter out most or all of the visible light spectrum, resulting in an unnatural image. Infrared filters are usually labelled with a number that describes the cut-off point in the light spectrum that they seek to eliminate. This is typically around 720nm. If your filter has a number lower than this, then it is letting through light in the red spectrum and is not really infrared. For the purposes of this challenge, the filter strength cut-off point will be 700nm (as stated on the filter - it is acknowledged that these ratings are not always accurate).
