Logarithmic value scaling in image-function

I have some files, that contain Fourier-transformed data, that is collected over time. If it weren't already transformed, i would use a spectrogram to visualize it, but since that is not an option i was using image().
I'm looking for a way to get logarithmic color scaling for the values that i feed to the function, but couldn't find it.
Can someone help me out?

Are trying to scale the colors so that changes are exaggerated? Here is an example of what you could do:
C = [1 2 3; 4 5 6; 7 8 9];
figure(1);
image(C);
C10 = 10.^C;
figure(2);
image(C10);
This takes your colors and scales them logrithmically.
