You can achieve Foveon-like images with deep colors and crisp individual pixels with your conventional (Bayer) camera. However, this comes at the price of losing 75% of your megapixels and having to work experimentally and outside the comfort zone of your camera manufacturer’s color science.
Owners of Foveon and 3-chip video cameras swear by their camera’s color reproduction, and for good reason. Other, conventional digital camera sensors can’t see true colors, but only record monochrome red, blue, and green pixels. In other words, a 24-megapixel camera with a conventional (Bayer) sensor doesn’t really record 24 million color pixels, but 6 million monochrome red, 6 million monochrome blue and 12 million monochrome green pixels.
