Infrared photography is one of the more unique niches of the hobby and can produce some amazing and wild images using light beyond our visible spectrum. In this episode, Alex digs into black-and-white infrared photography specifically. Infrared light is part of the overall electromagnetic spectrum, which includes our human visible light spectrum, which ranges from 380nm to 700nm or violet to red. Most infrared photography uses specialised film and filters to capture light between 700nm and 900nm. Today, we don't have dedicated IR films being newly produced like Kodak HIE, Efke IR820 or Konica Infrared 750, but we do have extended red sensitive films that can get into the near IR range. These films include Rollei Retro 80s, Rollei Superpan 200, Rollei Infrared, Rollei Retro 400s and FPP Black & White Infrared. These films have sensitivities beyond 700nm and between 740 to 750nm. Pairing these films behind a deep red (092/89b) or a true IR filter like a 093, RM90, or R72 filter will produce results typical of a traditional infrared film. You will have to consider the filter factory and over-expose your metering. You can use this website: www.fineart-photography.com to get started. Be prepared to spend a bit extra on the filters as a quality filter, which is an IR filter, will run at least 200 minimum for a quality unit.
