High ISO Noise Reduction on K20D - Does it do anything in RAW?

ksignorini · 07-18-2008, 10:13 PM

Does this setting do anything to RAW images?

Does it do anything at all? (I can't tell if it's making any difference.)

Also, what ISO = "High ISO"? 1600? 3200? What's the bottom end of "high"?

Thanks,
Kent!

Since you have a K20, this might be something you could research for us and post your results?
As an anecdote, I shot some available light pictures at a wedding a couple of weeks ago. ISO 640, noise reduction set to strong. The results were quite noise free.
I wouldn't mind seeing what the various settings do at various ISOs, but have never seen anything published in this regard.

I would also like to know what the bottom end of "high" is. For what I do 400ISO is high!

I asked my dealer to inquire about the high ISO NR, and he came back to me with this answer: High ISO NR works only on JPEG but leaves the RAW pictures unaffected. That's from a Pentax tech.
