Python: Adjust the scale of the 3d map

import rasterio
import numpy as np
from PIL import Image

names = ['Q4121F.tif', 'Q4122E.tif']

imgs = []
for n in names:
    imgs.append(rasterio.open(n))

image = imgs[0].read(1)   
print( np.shape(image) )
for img in imgs[1:]:
    tmp = img.read(1)     
    image = np.concatenate( (tmp, image  ), 0)

print( np.shape(image) )
print( image.max() )
print( image.min() )
image = 256*(image-image.min())/(image.max()-image.min())
im = Image.fromarray( image )
im = im.convert("L")
im.save( "heightModel1.png" )

Easy, fast.
