I don't know what you are doing and what you want to achieve. 

In grayscale mode the colors have to be in the range from 0 to 255 and
it's your responsibility to assure this is the case before you convert
your matrix to the image. You can do your matrix operations on matrices
of higher bitness and re-normalize them before you convert to uint8
using NumPy to feed into PIL.
