can someone enlighten me as to what IR photography is about? i'm a total noob here.
much appreciated. thanks in advance.
My little knowledge: IR photography is a special branch of photography which uses films / CCD to capture wavelength beyond our eyes can see, which falls from 680nm up to 1000 nm, which we called as Near Infrared spectrum. Beyond 1000 nm is far infrared and heat emmited.
Infrared film / CCD able to capture all visible light and some of the infrared wavelength but in order to produce more "pure" infrared effects, we use IR passing filter ( diff from IR filter which BLOCK IR wavelength ), but we photogs commonly refer IR passing filter as IR FILTER for short. R72, Wratten 89 etc.. are the passing filters which cut blue, green wavelength and only allow some visible light and IR to pass thru.
These films / CCD captures reflected IR waves from subjects and the more wavelength it receives, the whiter the subject appear ( for film ), the lesser the IR wave, the darker it appears. Usually healthy green vegetation will reflects more IR and therefore it apprear white in B&W photos whereas tree trunk, water, blue sky will appear dark due to these subjects absord IR rather than reflect it to the film / CCD.
IR photography produces surreal and out of norm type of photography and usually its whether you'll like it or you hate it!
Try out to see whether which will be you choice. For me, well its like my second life..ha.
