original imageI have a 16 bit tiff image. I would like to get following information from the image

1. maximum intensity count.

2. even though my bit size is 16 bit, why is my color bar restricted to 256 or 8 bits.

3. histogram I have written a sample code to do the same and I do not know what are the numbers on x and y axis represent. Could you please help me with this

4. import matplotlib.pyplot as plt

   import matplotlib.image as mpimg
   
   
   
    import numpy as np
   
   image = mpimg.imread('r1Ls01N000001.tif')
   
   plt.imshow(image,cmap='gray')
   
   plt.colorbar()
   
   plt.show()
   
   plt.hist(x=image.ravel())
   
   plt.show()
   
   imax=np.max(image)
   
   print(imax)
   

Result Imax value will be displayed as 264, is the 264 intensity count or bit number? Resulting image from my code
