Hot Spot
Lenti compatibili per la fotografia infrarosso
Generalmente viene chiamato hot spot in punto caldo che viene a formarsi nel centro del fotogramma con diaframmi chiusi .Di solito si manifesta nella forma di un cerchio luminoso, talvolta a forma dell'apertura del diaframma piu o meno evidente nel centro dell'immagine.Il problema , se presente in un ottica , e' piu evidente con l'aumentare del numero f stop "diaframmi " , quindi piu si chiude il diaframma e piu e' piu evidente l Hotspot.
