I assume you want a high-contrast result. Kodak IR film, with your subject lit properly with tungsten bulbs, gives you little skin detail and some halation on very bright reflected surfaces. Grain is big. You'll have to bracket your shots.(posted 9087 days ago)For less grain and no halation, try Tech Pan and a high-contrast developer. I've only used this combination for cityscapes, but it might give you what you want.
What have you been using that's given you poor results?
