Ok, I have been searching the internet high and low today for a good starting point on Rollei IR400 as I have a roll in the post for tomorrow and if the weather is anything like the last couple of days it would be perfect timing.
I know there are many pages and threads about IR film and many specifically for Rollei IR400 but they have all left me in some confusion.
I understand that using an IR filter the film will need to be shot between ISO3-25 with ISO6-12 being popular choices. My question is, do I work out the exposure at ISO6-12 with or without the IR filter on the camera as they will give dramatically different shutter speeds.
I may be missing something really simple but it's got me a bit confused today.
Regards
Jim
