I have a Nikon N80 and to my dismay I found out I can't use infrared film with it due to some annoying innovation inside that aids with ensuring the correct # of exposures per roll, but fogs up any IR film... anyway, I just came across Infrared filters online but have never heard of them. Ok, so they block visible light and let IR waves pass, but does it just produce BLANK photos with reg. film? Basically, I want to know if an IR filter would allow me to still take IR photos.. I think the answer is no. In that case, are the filters just for enhancing the quality of photos taken with IR Film..?
