In the "imshow" function your can specify a viewing range (i.e. tell the 
function that a pixel value of 0 equals to black, and 100 equals white).

The default is to let 0 equal black, and 255 white, but at times you 
want to change this. If "imshow" didn't have default arguments, I would 
have to write
  imshow(im, [0, 255])
a lot of times, which would make me go insane (some might argue, that 
it's too late...). Since imshow supports default arguments I just write
  imshow(im)
which is a lot easier to read (IMHO).
