A problem with a film with enhanced red and infra red sensitivity is that exposure meter readings with the red filter are not necessarily going to be very accurate anyway. I've only used this film once, and I ended up by overexposing inadvertently (Leica M + filter factor). So, you probably don't know if you've underexposed or not. You could try a one stop push. Your subject matter probably wouldn't cause excessive contrast which usually is the result of pushing. Incidentally, photographing b+w subjects really negates the purpose of this kind of film. It is most useful where the red sensitivity can give added value to subjects of certain colours, like green foliage in natural light. Good luck.(posted 8416 days ago)
