1. A method, comprising: copying each green intensity value in a raw color digital image from an area sensor array into a corresponding pixel location of a grayscale digital image where each pixel in the color digital image has only one color intensity value, either a blue intensity value, a green intensity value or a red intensity value; for each red intensity value in the color digital image: adjusting the red intensity value to match a local dynamic range of green intensity values; inserting the adjusted red intensity value as the grayscale intensity value of the corresponding pixel location of the grayscale digital image: for each blue intensity value in the raw color image: adjusting the blue intensity value to match a local dynamic range of green intensity values; inserting the adjusted blue intensity value as the grayscale intensity value of the corresponding pixel location of the grayscale digital image.
