A commercial package called DxO Optics Pro v5 has an interesting twist
on de-noising: it does de-noise of raw images before de-mosaic.
An elegant idea really, as de-mosaic can't help but diffuse the noise
across more pixels and thus make de-noising harder / less accurate.
This approach would certainly suggest separating de-noise and sharpen.
Though I believe there are some other tools which deliberately integrate
the two in order to better coordinate their processing. But I don't
know
what the nature or benefit of that coupling is.
I think I agree with you. Sharpening and denoising should be kept apart.
But i don't know if denosing should be done before or after demosaic.
Anyone else has a opinion on this?
