Tips for IR shooting

[jpa66]

Hi all.

I'm going to be shooting some I film ( Rollei and Efke Aura ) in 120 format with a Rolleiflex. I've never shot any IR other than HIE ( which I miss dearly ), but I think that I have a handle on which iso to use/experiment with.

My question is how many stops should I compensate for use of the filter? I have a Rollei Infrarot filter ( the Rollei IR filter ), which I've never used. I've only ever used a red filter in 135mm. If anyone has any tips or advice, I'd appreciate it.

Thanks,
Jan

i shot with the ekfe aura and if you go to their website, there is link to a data sheet. it will give you a few options with different filters. different filters, different strengths. they are pretty accurate but make a test with your first roll; 1 stop over, 1 stop under and normal. i shot a grey card with a hand beside it. the efke is really really slow so it is kinda tripod only shooting and the film is very very fragile. careful handling is mandatory. i had a tough time getting it into the scanner tray for the nikon 9000. however the flowers that i shot were beautiful. a little labour intensive but sometimes worth it. good luck.

If you want Efke IR to look like IR you have to use an IR filter. I use Hoya R72 and shoot at one second and f 11, some like f16 but I don't. This of course is in bright sun. I have few other times for different scene types, but I will give them to you if want. I develop in HC-110 at again a time I will be happy supply.

I on an IPad so posting a photo too difficult, but I may do it later.

Edit: here is one at f11 and 1 second:

OK, corrected the filter name - it's a Rollei Infrarot, so it's Rollei's version of an infrared filter. I can't seem to find information on how many stops that I should compensate for it's use. Not sure exactly what filter factor it is.
