Scope note
Infrared photography technique commonly applied to a variety of techniques including aerial photography and art examination. False color infrared is preferred for vegetative and hydrologic studies. False color infrared film is sensitive to ultraviolet, visible and infrared radiation to approximately 900 nm. When the film is exposed with a yellow filter, the emulsion layers become sensitive to only green, red and infrared wavelengths. Blue radiation is absorbed by the filter; hence, the greater haze penetration ability of infrared film. In art conservation, the resulting false color images can be used as a noninvasive means of identifying the pigments that have been used in a painting or underdrawing.

Infrapunafotograafia tehnika, mida tavaliselt kasutatakse koos teiste mitmesuguste meetoditega, sealhulgas aerofotograafia ja kunstiteoste uurimine. Taimestiku ning hüdroloogilisteks uuringuteks kasutatakse enamasti valevärvilist infrapunafotograafiat. Valevärviline infrapunafilm on valgustundlik nähtava ning ultraviolett- ja infrapunakiirguse suhtes. Kui filmi säritakse kollase filtriga, muutuvad emulsioonikihid valgustundlikuks ainult roheliste, punaste ning infrapunaste lainepikkuste suhtes. Filtri abil imendub sinine kiirgus – sellest tuleneb ka infrapunafilmi suurem sumedust läbistav omadus. Valevärvilisi fotosid saab kunstiteoste konserveerimisel kasutada mitteinvasiivse vahendina pigmentide tuvastamiseks, mida maalimisel või alusjoonise tegemisel on rakendatud.
