If some image (.psd in my case) of sufficiently big size (to have Gaussian blur on by default) contains zero (in my case magnitudes of the Fourier transformation), and you turn the Gaussian blur off, you will get NaN on the whole image.
This is probably caused by the 'log' used while reading the image.
