title: tifffile in Python not writing 16bit tiff
body: <p>I had a look for duplicates but I'm not sure similar questions had the answer...</p>
  
  <p>I'm using tifffile in Python to read a multipage tiff (16 bit), take the first channel page/channel, blur it and save it as a 16 bit tiff.</p>
  
  <pre><code>import os
  import matplotlib.pyplot as plt
  import tifffile as tiff
  from scipy import misc
  
  tiff_list = []
  
  for i in files_list[0]:
      tiff_list.append(tiff.imread('/filepath_to_tiff_folder/'+i))
  
  blurred_list = []
  
  for i in tiff_list:
      blurred_list.append(ndimage.gaussian_filter(i[0], sigma=3))
  
  for i,v in enumerate(blurred_list):
      misc.imsave('/filepath/testblur2/'+str(files_list[0][i])+'_Brightfield_Blur.tif', v)
  </code></pre>
  
  <p>Here, <code>files_list</code> is just a list of the file names of the tiffs.</p>
  
  <p>The above code works absolutely fine for blurring and saving the tiff, but it saves it as 8 bit instead. </p>
  
  <p>Is there something in the above I can add to keep it 16 bit or do I have to use another method?</p>
