1. A method of sample analysis, comprising: directing a charged particle beam toward a work piece; detecting emissions from the work piece at multiple points impacted by the charged particle beam; using the emissions to determine the base layer mineralogy image and the top layer mineralogy image. receiving a base layer mineralogy image and a top layer mineralogy image; sequentially, via a computer processor and for each pixel in the base or top layer mineralogy images: determining a base layer value from the pixel in the base layer mineralogy image; determining a top layer value from the pixel in the top layer mineralogy image; determining a luminosity value from one of the base layer or top layer values; and determining a blended image value for each pixel of a blended image using one of multiple blending methods, the blending method used being determined on a per pixel basis as a function of the luminosity; and generating a blended mineralogy image using the blended image values; and displaying the blended image.
