I am having a problem with ListContourPlot not correctly shading my plots. I have a data set of approximately 500x500 points. Most of this range has a value near zero, though there is a "spike" near the center of the data. This spike is a Gaussian function that covers (FWHM) roughtly 40x40 of the data set. The problem with ListContourPlot is that it just shows it as a solid white circle with the rest of the plot black. There is no varying shades of gray showing how the data falls off. A good example can be seen with:

Is there any way I can properly "scale" my contour plots?
