discrete fourier transform differences between fft and fft 2 on a image. Which one should i use for discrete fourier transform?

If i use fft of an image(the discrete case) i amgetting an result based on a 1_D sum of vectors

this is the log of fft , but if i use fft 2, il get a different result, and i know, that fft is for discrete case,(from my opinion the result from above is correct) but i found everywhere that people use fft2(this one is for fast fourier transform conform matlab), am i missing something?

and this is the result of fft2.

can somebody explain, pllzzzzz.
