Converting image to array, performing FFT of 2D array, and converting array back to image

How does it look if you autoscale z?

Can you run your VI so the intensity graph contains data, then right-click the intensity graph followed by (data operation...make current value default). Now place this intensity graph into a new VI, save, and attach it here.

Here is the VI containing the intensity graph.  I have also autoscaled Z.

Do some logarithmic mapping.

It works!  Thank you so much for your help!
