Abstract

Početak razvoja IR tehnike kreće od istraživanja zvijezda, zdravlja lišća te u medicini i kriminalistici.

Infracrvena tehnika u području fotografije se razvija od 1910. god. te je usko povezana sa poznavanjem zakona fizike. Početak razvoja nalazimo u analognoj fotografiji gdje su se koristili C/B filmovi i filmovi u boji. U analognoj je svjetlost padala na film, dok u digitalnoj film zamjenjuje senzor, što omogućava veću pohranu informacija i bolju obradu fotografija. U IR digitalnoj fotografiji se uspijeva raznim programima imitirati IR fotografija. Za postizanje IR fotografije osim poznavanja zakona fizike potrebno je poznavati i fotografsku opremu te razne načine fotografiranja. S obzirom na efekt koji želimo postići koristi se određeni fotoaparat, koji može biti ili IR modificiran ili klasični fotoaparat samo sa IR filterom. Filter, fotoaparati te ostala pomagala se razlikuju po proizvođaču i karakteristikama.

Pravila koja se koriste u klasičnoj fotografiji razlikuju se od pravila u IR fotografiji. U IR tehnici od boje je važnija kontura te razni kontrasti i kompozicija, tako da će isti motiv drugačije biti naglašen u klasičnoj fotografiji odnosno u IR. Osim toga tu je jako bitna rasvjeta, tj. Sunčeva oscilacija. Ako je zračenje Sunca veće ili manje morat će se s obzirom na to koristiti modificirani IR fotoaparat ili klasični sa filterom.

Jedna stvar ostaje upitna, koliko je zapravo IR fotografija umijeće,a koliko tehnika?

Abstract (english)

Research the health of foliage, astronomy and forensic criminology are beginning of developing IR technique. IR technique in photography is development since 1910. and is closely related with laws of physics. Developed IR photography was begun in analog photography where it use C/B films and color films. In analog photography light is falling on film but in digital photography it is falling on sensor. That is better because in digital photography is big storage information and better manipulation with pictures in many programs as imitations of IR photography. For getting IR picture except law of physics we need to know how to use photography equipment and way of photographing. We can use different camera like IR modified camera or classic camera with IR filter considering which effect we want to accomplish. Filter, cameras and other devices are different which depends of manufacturer and properties we want. Rules in IR photography are different then rules in classic photography. In IR technique contours, contrast and compositions are more important than colors, because of that same motive are different in IR and in classic photography. To decide which type of camera is better to use, classic or modified camera, depend on oscillation of the sun. There is always one question, is IR photography art or technique?
