title: Image.open gives error Cannot identify image file
body: <p>I am trying to open a geotiff file with PIL's Image function. It raises the error: </p>
  
  <pre><code>OSError: cannot identify image file 'Whatever\\image\\I\\use.tiff'
  </code></pre>
  
  <p>I saw the question asked <a href="https://stackoverflow.com/questions/19230991/image-open-cannot-identify-image-file-python">here</a> for example, the sollutions are to either use </p>
  
  <pre><code>Import Image 
  </code></pre>
  
  <p>instead of </p>
  
  <pre><code>From PIL import Image
  </code></pre>
  
  <p>Which is I think an outdated sollution; I can't import Image. An other sollution is to update pillow to 2.9, but 5 years later we are on 5.0.0. I tried 4.0.0 as well where I receive the same error. 
  Is there an up to date sollution for this? </p>
  
  <p>here is my code and <a href="https://www.dropbox.com/s/uoz8bzgge5nvdec/rgb_CGI.tiff?dl=0" rel="nofollow noreferrer">here</a> is a link to a file:</p>
  
  <pre><code>image_path = 'each\\image\\I\\use.tiff'
  
  from PIL import Image
  Image.open(image_path)
  </code></pre>
