Yesterday I was given three rolls of SFX 200 (120) and would like to shoot them. However, I don't have any experience with infrared, have no filters, and am not interested in buying any I'd like to shoot this film as just plain B&W.

It expires this month, so what ASA should I rate it at? Also, I read a long time ago that IR film requires careful handling: load in complete darkness, tape over the film door window, be careful when loading into reels, etc, etc. Is this the case, or can I "cut corners" as with regular B&W film?

Thanks in advance
