Ib qho ntawm zaj duab xis stunt photography txoj kev siv duab xoo duab ci raws li lub teeb ci, thiab cov yeeb yaj kiab photosensitive siv yog rhiab los ntawm cyanine zas xim uas nqus cov duab infrared wavelengths. Infrared spectrum siv rau kev yees duab yog nyob hauv thaj tsam ntawm 700 txog 1300 nm. Thaum tua, ntxiv cov xim liab tsaus nti rau sab xub ntiag ntawm lub lens.
Cov xim lim xim dub lim tawm ntawm ultraviolet rays thiab pom lub teeb nyob rau hauv tshav ntuj, lossis irradiates cov kev kawm nrog lub ntsej muag infrared. Cov duab yeeb yaj kiab tsuas yog nthuav tawm rau tsuas yog infrared rays thiab ib qho me me ntawm lub teeb liab, thiab tom qab ntawd raug rau kev txhim kho dav dav kom tau txais cov yeeb yaj kiab zoo. Vim tias infrared rays tuaj yeem nkag mus rau hauv soot thiab pos huab, koj tuaj yeem tau txais cov duab meej hauv cov duab nyob deb thiab ua kom siab. TV siv los sim ua kev hmo ntuj hauv nruab hnub nrig.
Raws li kev ntsuam xyuas, duab ci ci tuaj yeem ncav cuag ntau dua 40% hauv lub teeb hluav taws xob ntuj. Hauv kev yees duab dub thiab dawb, lub teeb pom kev tuaj yeem thaiv los ntawm liab mus rau xim liab rau tsaus liab los ntawm kev siv cov ntxaij lim dej tshwj xeeb, kom cov duab infrared yog rhiab ntawm zaj duab xis. Piv txwv li, "Ryden 87C" lim tuaj yeem thaiv tag nrho cov pom kom pom los ua cov duab thaij duab infrared coj los ua teeb meem. Qhov kev lim no yuav luag tsis pom rau qhov muag liab qab. Hauv kev ua haujlwm tshwj xeeb, kev ua kom pom tseeb yuav tsum tau kho ua ntej ntxiv cov lim. Coj mus txhaj tshuaj kom pw raws li qub. Hauv kev hais txog duab, duab infrared tuaj yeem siv nrog "Ryden 25" liab iav, uas tuaj yeem ua cov duab infrared pom tseeb dua. Yog li vim li cas yog vim li cas rau infrared photography? Kev tsom xam ntawm cov khoom pom tau zoo tshaj plaws pom los ntawm tib neeg lub qhov muag, xws li xiav dej saum npoo thiab ntuj, lawv tsis tuaj yeem cuam tshuam ntau lub teeb duab infrared, yog li txawm hais tias cov duab ntawm cov yeeb yaj kiab dub thiab dawb yog qhov qub, cov duab infrared qhia tau xim tsaus nti.

Infrared tsis tsuas yog muab cov txuj ci tsim tshwj xeeb rau kev yees duab, tab sis kuj vim tias nws qhov kev sib hloov siab, nws kuj tuaj yeem thaij duab ntsej muag nrog huab thiab pa taws, thiab feem ntau yog siv rau kev tshawb nrhiav thiab kev tub rog kev soj ntsuam hauv kev tshawb fawb. Kev siv duab ci ci sab nrauv muaj cov yam ntxwv ntawm kev nkag mus rau sab hauv daim duab mus rau sab hauv xim, thiab nws tseem tuaj yeem txiav txim siab qhov tseeb ntawm cov xim nto moo ntawm cov masters.
