No, it isn't. Not directly anyway. You may be able to get some
approximation of this by using Core Image, but even then I believe it
still operates on the loaded bitmap data rather than the RAW data.
If you want to control the generation of the RAW file's bitmap,
you'll likely need to wrap dcraw (the basis for many RAW converters -
http://cybercom.net/~dcoffin/dcraw/) internally and feed it the
parameters you want.

NSImage, when presented with a RAW image file from a camera (a CR2,
CRW or NEF) file for example, will decode the image and present the
NSBitmapImageRep in the NSImage with a great 16 bit converted
file. This is right cool but I have a question.
Is it possible to control any of the parameters in the RAW
conversion? I am concerned with any Chroma or Noise Reduction
applied to the image.
