Python Image.load() returning pixels greater than 250

I am loading my Image file using Image.open("image.tif"). Then i am using Image.load() to generate a pixelMap of the image. Then i am storing each pixel into an array. The following code describes this process. Then I want to create the ascii value of each pixel and store it in a string. So I going through each pixel in my pixel array and then change the pixel value to ascii value. However I am having an error because I am getting some pixel values greater than 250. How is this possible. Also, it is b/w image. What am I doing wrong?

self.filename = filename
self.im = Image.open(filename)
self.pixelmap = self.im.load() #Loads the image as a map of pixels
self.arr = []
for i in range(self.im.size[0]):
    for j in range(self.im.size[1]):
    mypixel = self.pixelmap[i, j]
    self.arr.append(mypixel)


for i in msgFile.arr:
    self.message += str(unichr(int(i)))

something like this?

from PIL import Image
import numpy as np

image = np.asarray(Image.open('image.jpg'))
_y, _x, _z = image.shape
str_array = [str(image[y][x]) for y in range(_y) for x in range(_x)]
