Lightroom: Relative noise reduction - possible?

I don't even know if this is possible, but it seems like it should be and it would be FANTASTIC to have.

Basically when I shoot a large event I'm often using auto-iso. That makes it difficult to bulk-edit the noise reduction. Some images (say iso 400 to 800) need little reduction - perhaps 5 or 10. Others need 20 or even 25. (I rarely go above that level because it starts to look ridiculous.)

I would love the ability to do a sliding scale for noise reduction. If the iso is 400 then apply level 5. If it's iso 6400 then go to 20. From there the sliding scale should be easy to generate.

It would be even better if it can handle adjusting according to exposure or shadows adjustments. If I give it +1EV adjustment then that's the same as one stop higher iso. Something like that. (Not sure that's the exact amount that would be appropriate; just getting the idea out there.)

Who's with me? :)

Well, the ISO is in the metadata, so theoretically it should be possible for PS to read that and then apply a predefined value. I think it should somehow already be possible, but you would probably need a script.

I support your idea, it would be a pretty handy feature!

Crap, did I post this in Photoshop? It was supposed to be in Lightroom. I was writing it in a hurry while someone was waiting for me. :)

Oh no you did write it in Lightroom, sorry my bad. But nevertheless, the same goes for Lightroom ;)

I'm pretty sure that there is already some NR applied upon import based on ISO and camera metadata.

Follow the link to Jeffrey Friedl's bulk develop plug in it sounds like it would meet your needs

Another option for initial detail settings based on ISO:

ISO Detailer ( written by yours-truly / me )

PS - For relative noise reduction in bulk, I recommend Gazoo.
