Help exposing Infrared b/w film, please.

Thanks, Roger.

Another good reason for a cheap filter...in case you buy the wrong one :O).

I think it'll work with the partial box of HIE I have. The other films I guess not.

Or maybe it would with the other films and LONG exposures. Or REALLY LONG exposures.

Another project I had was taking the IR-block filter out of an old video camera, illuminating a changing bag or box with an IR LED and putting the IR-enlightened camera inside the dark enclosure. I was considering how to be sure the LED's had no visible component...my filter could do that.

I wanted to cut 5" rollfilm down to other sizes & have found working with that roll (1000') kind of traumatic in the dark. If I could 'see' it would be less stressful.

OK, this is a follow up post to my post stating that I received the free trials of the new Maco Infrared film.

By the way, I got good results with the maco prototype at ~EV+9 with a #87 and ~EV+7 with an rm72. Look for roughly sunny 16 light and compensate in this way and you're good to go. Enjoy.

Pardon me if I am dense. Are you saying "EV+9" meaning take the exposure value as read by a conventional meter and add nine more stops?
What ISO are you setting the meter for?

Yes, that's what I mean, assuming that we are speaking of the same prototype film. I meter as if it were ISO 200 film, add about nine stops however I please, and that's it. Actually, you know what, meter schmeter! You won't want to shoot the film unless you have pretty hard, sunny 16 light

N.b. compared to the current Rollei IR film, this is considerably more IR sensitive- two stops or so. It is not unusual for me to shoot the current Rollei film at EV+12 (!) with a #87.
