Regular camera lenses produce chromatic aberration: Red, Yellow Blue do not

focus equally on the CCD sensor plane.Apochromatic lenses, like BRG might use, focus the many varied color rays oflight together on the CCD sensor plane. Regular lenses do not and therefore produce color image distortion.It would then seem beneficial for accurate coin color rendition to use an APOlens.This would include types of copy camera lenses as well as film enlarginglenses and specialized apochromats made for cameras.The lower curls on this Morgan Dollar have a magenta tint which is the earmark of chromatic aberration. Out of doors photos would also have an accompanying yellow-green tint.To see old comments for this Journal entry, click here. New comments can be added below.
