I have problems processing red
It's not just you , go to flickr , do a search for scarlet tanager photos , you'll see a whole Bunch of pix with blown out red.
It has to do with the way colors are processed. You want to use adobeRGB RAW color space , not sRGB , in camera and when processing ,, which will help a little.
Underexposing or overexposing to help with the reds , generally won't make a huge difference either since the problem reds are usually of a very narrow value in wavelength.
If you come up with a great fix for digital cameras, I would love to know what it is .
