I love Konica 750 IR film...I use it at ISO 50 with a 25 red filter and meter thru the lens...works beautifully. Since the film is not as contrasty as the Kodak HIE film, you may find that you'll want a higher contrast in your papers. My personal preference is to use Oriental Seagull Graded papers, either 3 or 4 with a combination of Dektol and Selectol Soft paper developers (2 minutes in Dektol, water rinse, then 1 min in Selectol Soft). You can also use a variable contrast paper and use a higher contrast filter on exposure.
