I know, I know, many people have asked for noise reduction in RAW files before. I think sooner or later you'll need to do it as it is a real concern and has lots of potentials for you, as the developer.
Consider this: What is ISO noise in a CCD? Is the noise in adjacent channels in the RAW file (R, G, B or other colors) really that correlated?
When the bayer interpolation is done, basically the noise is now "spread" to the other channels and I can only assume that dealing with it gets more difficult. PS CS2 has good support for import/exporting DNG files. Now, if you could open, process and save back a DNG file in NeatImage, WIHTOUT doing the beyer filter (that is, working on the RAW file's channels separately) I think you could potentially:
- Make the noise reduction independant of the RAW processing method
- Reduce the niose more effectivley
- Make the noise profiles independant of the changes in WB or exposer or other settings in the RAW converter
- Make somthing unique, with no competition for the moment
