A simple script designed to process diffraction patterns to reveal weak reflections. The script does this by taking the reciprocal cube root (ie image ^-0.333) of the image. The cube root greatly compresses the range of values, and the use of a negative power inverts the image - it is easier to see weak black spots on a white background. You may want to adjust the histogram to further enhance the spots. If the script it run with ALT key held down, the option to change
the exponent is given.
