I have been using
Aperture lately for my digital photography post-processing. The work flow and smoothly working tools are addicting, but I have found a fatal flaw in its handling of
RAW files. Aperture has no way of handling
hot pixels. These dead pixels are a fact of life on digital cameras; although some cameras map these out for you from the factory, more will appear in time. Adobe, knowing this fact, built hot pixel removal into Adobe Camera RAW. Apple's algorithm, however, not only doesn't remove them, it enhances them into a bright dot, apparently falsely thinking the bright, out of place single pixel is image detail to be enhanced. This causes the single failed pixel to become a bright blob on your photo.
