My understanding for this film is that's it's only ASA400 when shot unfiltered, and somewhere between 6 and 25 when shot just in the IR range, dependent on the filter used.
Sure - Emulsive and Kash Photo both mention it. I'm on my tablet, so I can't add links irritatingly, but I just googled "shooting rollei infrared film".Do you have a source for that?

Taking exposure info from one meter/sensor/film to another will never work well for IR. The meters used are not designed for IR.Ah. Just read the Emulsive article and the ISO reduction represents the amount of light the filter blocks. I measure the light loss with my digital camera then apply it to film. I still dev as for ISO 400 though, even though (with my filter) it's actually about ISO 0.5
HC for 7:00 at 20°C appears to have done the trick. Negatives look a little thin and underexposed, but the rebates are spot on. I'll scan them when they're dry and post anything that's half way decent.Anyone with any insight for processing Rollei IR shot at EI25 with a 720nm filter..? I've got Ilfotec HC or DD-X on hand...

Anyone shooting with a full spectrum converted mirrorless and using it for ALL your photography, including normal colour?
Would love to go down to a single body, mirrorless seems like the right way to go (no need to worry about not being able to use the viewfinder with filters on) and ideally want to go with a high end camera - a Nikon Z7II ideally, but,.... well it feels like a bit of an experiment at the moment, and that would make it an extremely expensive experiment! Want to understand if there are any downsides that make a single body for everything impractical, or whether it really is the do-it-all-no-downsides option it should be!
Not by any means all, but my A7ii has been full specrtum converted & I use it with a clip in hot mirror most of the time for normal shooting.Anyone shooting with a full spectrum converted mirrorless and using it for ALL your photography, including normal colour?

these are the clip in filters I've heard about!
With someone standing on the footbridge it could make a interesting feature. IMONice pair, shame about the footbridge is it in the first?
That is a cracking first shot,First shot with an IR camera, using a less than ideal cheapo lens...

Would be good to add this into other thread, my mistake when I started this thread.There is another thread here with a similar title that's got quite a bit of useful information in it if anyone is interested: https://www.talkphotography.co.uk/threads/ok-then-lets-see-your-infrared-images-please.493937/
