I have found that the bandpass correction (under FFT) can be very helpful in
removing the sort of background that is in your image. The idea is to
consider the overall pattern of illumination to be a long wave pattern, and
to filter it out. Go to FFT>Bandpass correction, and set the short
wavelength to zero, and the long wavelengths to something like 50 or 100,
depending on your resolution, I uncheck anything about adjusting contrast,
etc.
Best of luck,
Joel
