also i like to have a big distance from each bump 
everything i try is to close

>>You can probably do it in Blender too, using clouds texture, custom

>>
>>- new white image.

>>- rgb noise filter, move sliders to max so you get lots of dots.
>>
>>- desaturate (lightness one is fine, try others if you want).
>>
>>- blur (normal one will do here).
>>
>>- curves, make a _/ curve , the histogram should show a sharp spike on

>>
>>- guassian blur, 1-2 pixels to smooth.
>>
>>- invert if you need the bump map that way.

>>As last note, I decided the dot density was too low, so before invert
